•Prepacked gravity-flow columns provide convenience, save time, and increase the reliability of your results.
•Purification of antibodies in 30 min allows you to quickly obtain and store your target protein in order to avoid the inherent dangers of protein instability and degradation associated with slow and long purification runs.
•High purity and recovery with purity > 95% in one step and recovery typically 70% to 80%.
•High binding capacity such as Protein A/Protein G GraviTrap ~ 35 mg human IgG/column.
rProtein A/Protein G GraviTrap are prepacked gravity-flow columns designed for fast and efficient manual purification of monoclonal and polyclonal antibodies, antibody fragments from cell culture supernatant, and biological fluids. The antibodies are simply captured with high specificity on protein A and protein G ligands in gravity-flow columns. You do not need any other instrument with this protocol because the entire process relies on the flow of gravity. The yield varies from 20 to 50 mg of purified antibodies depending on the ligand you use. The columns are reusable up to five times.
Designed for efficient, small-scale purification and screening of histidine-tagged proteins from different sources.
His Mag Sepharose Ni products are magnetic beads designed for efficient, small-scale purification/screening of histidine-tagged proteins from different sources. Histidine-tagged proteins are captured using immobilized nickel ions followed by collection of the beads using a magnetic device. You can use magnetic beads to simplify sample handling during small-scale purification.
His Mag Sepharose Ni delivers:
High-capacity small-scale purification of histidine-tagged proteins from different sources
High purity and yield
Easy parallel screening of histidine-tagged proteins with high repeatability
Scalability—Simple capture of histidine-tagged proteins from small or large sample volumes (low microliter to milliliter scale)
The beads are available in three pack sizes: 2 × 1 ml 5% medium slurry, 5 × 1 ml 5% medium slurry, and 10 × 1 ml 5% medium slurry—a 1 ml 5% medium slurry is the same as 50 μl sedimented medium. A 1 ml medium slurry is sufficient for 5 purification runs according to the recommended protocol.
Together with MagRack 6, a separation tool for handling the beads in microcentrifuge tubes, up to six samples can be processed in parallel. You can easily screen a larger number of samples in parallel with high throughput on a robotic device.
The magnetic bead format has excellent properties for small-scale experiments. The high density of the beads allows rapid capture by magnetic devices while the visibility of the beads ensures reliable collection of the bound histidine-tagged proteins in the purification procedure. The characteristics of the media are summarized in Table 1. All the products are provided with protocols optimized for purification of histidine-tagged proteins.

To fulfill its responsibility towards the consumer, BIOTECON Diagnostics decided to develop high-quality detection kits for food allergens.
To fulfill its responsibility towards the consumer, BIOTECON Diagnostics decided to develop high-quality detection kits for food allergens. Therewith, the well-known and respected spectrum offoodproof® real-time PCR kits is extended by another interesting product division.
The first allergen kits that will be launched by the company from Potsdam, Germany, are the foodproof® Celery Detection Kit and the foodproof® Gluten Detection Kit. More allergen kits for the detection of soy, peanut and hazelnut will follow soon. In combination with the foodproof® Sample Preparation Kit III for theextraction of plant DNA, this kits allows simple and safe detection of allergens in all kind of foods. Depending on the source of literature the prevalence of food allergies is between 2 – 4 % for adults and 4 -8% for children.
The foodproof® Sample Preparation Kit III allows the extraction of highly purified DNA even from complex foods or processed matrices. To validate the foodproof® Allergen Detection Kits final products, raw materials and swab samples have been successfully tested. The kit cannot be only used for foods, finished products and raw materials, but also for cleaning validations. In addition, BIOTECON Diagnostics has developed a standardized reference material, Allergen RM 800, to create a standard curve for exact quantification.
More allergen kits for the detection of mustard, sesame, lupine and crustacean will be developed next year. Also it is planned to develop multiplex kits, to detect up to three different allergen-parameters within one reaction.
Food allergens became more important, because the frequency in the population has grown in the last decades. The reasons are still not totally clear; often it is credited to changing environmental influences and diets. Even the smallest amounts of allergens can cause severe allergic reactions up to life-threatening symptoms. For the consumer, the only protection is avoidance. According to EU-regulation 2007/68/EG 14, different allergenic ingredients have to be labeled in Europe on the products. Until now there is no threshold value in Europe or elsewhere. Therefore, the zero tolerance rule applies, even foods that only contain traces of allergens have to be labeled accordingly.
Dr. Kornelia Berghof-Jäger, Chief Executive Officer (CEO) of the Germany-based corporation BIOTECON Diagnostics therefore announced that „the expansion of our product portfolio by test kits for the detection of food allergens is a consequent continuation of our strategy to cover all aspects of food safety diagnostics bymolecular methods.“
„The new product line allows the users of our foodproof® system to enter new markets with the existing laboratory equipment without any additional financial investments.” emphasizes Alois Schneiderbauer, Chief Business Officer (CBO) of BIOTECON Diagnostics stated.

A novel ophthalmic solution from R-Tech Ueno (Tokyo, Japan) made using Novozymes Biopharma’s recombinant human albumin has recently obtained FDA approval to undergo Phase I/II clinical trials in the United States.
Novozymes Biopharma, part of Novozymes A/S world leader in bioinnovation, today announced that an ophthalmic solution made using its recombinant human albumin, has been approved for Phase I/II development by the FDA.
Designed by R-Tech Ueno, RU-101 ophthalmic solution is being trialled as a therapy for severe dry eye, for which no effective treatment is currently available. The recombinant human albumin is part of Novozymes Biopharma’s albumin range. Novozymes Biopharma has a strong reputation in the industry for helping customers in the safe and successful commercialization and approval of new products.
The prevalence of severe dry eye, where patients suffer from instability of the tear film, continues to increase. It is the most diagnosed of all ophthalmic disorders and estimates put the market at approximately 1.5 billion USD. The trials for RU-101 ophthalmic solution will move ahead in two stages, the first of which will assess safety using a placebo control, and allow confirmation of the maximum dose. The second stage will then use this maximum dose for 12 weeks to evaluate the safety and effectiveness of RU-101 ophthalmic solution.
Dermot Pearson, Marketing Director at Novozymes Biopharma said, “Novozymes is dedicated to supporting our customers in the drug development and testing stages, and in assisting with the optimisation of their pathways through regulatory approval procedures. We are therefore delighted that RU-101 ophthalmic solution has been approved for clinical testing.”
Novozymes Biopharma’s recombinant albumin is designed to provide quality performance benefits when included in drugs developed by our customers. It was selected as a key component of this novel therapy back in 2011, due to its proven high quality and enhanced safety profile. Animal-free, with an exceptional purity profile and convenient liquid format at room temperature, recombinant albumin delivers consistent levels of quality, leading to reduced lot testing and vendor auditing.
All Novozymes’ recombinant human albumins deliver stable, safe and regulatory compliant ingredients for drug delivery and formulation, and are compliant with the National Formulary (NF) rAlbumin human monograph published by the United States Pharmacopeia (USP).

The GeneArt® CRISPR Nuclease mRNA is wild type Cas9 as mRNA, for genome editing using CRISPR-Cas9 technology.
High-efficiency CRISPR genome-editing tools for multiplex editing
The GeneArt® CRISPR Nuclease mRNA is wild type Cas9 as mRNA, for genome editing using CRISPR-Cas9 technology. Ready-to-transfect Cas9 mRNA circumvents the need for time-consuming cloning steps required when using CRISPR vector systems. Cas9 mRNA can be co-transfected with in vitro transcribed guide RNA (IVT gRNA) or a synthetic gRNA expression cassette containing U6 promoter. The gRNA expressing cassette and IVT gRNA template can be ordered as GeneArt® CRISPR Strings™ DNA, a 500 bp DNA fragment. Following transfection, the Cas9 protein is directed by gRNA to target specific genomic locus. This system allows multiplex genome editing, where multiple target gene sequences can be edited simultaneously in a single transfection reaction with the addition of multiple gRNAs. The system is versatile and simple to use, and changing target specificity only requires a change in the design of the GeneArt® CRISPR Strings™ DNA.
