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.

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.

GATC Biotech, a leading provider of advanced genome analysis and diagnostic services, launched today INVIEW ONCOPANEL, a comprehensive multigene cancer panel for solid tumour profiling.
The next-generation sequencing (NGS)-based panel consists of 50 cancer-specific genes that could add diagnostic, prognostic and therapeutic value to personalised care.
“INVIEW ONCOPANEL was the lone missing member of our cancer research and diagnostics portfolio,” said Dr Markus Benz, COO of GATC Biotech. “The service perfectly complements our liquid biopsy-based assay GATCLIQUID ONCOPANEL. It enables researchers and clinicians to screen not only liquid biopsy samples, but also tissue biopsy samples for genomic alterations. These carefully selected genes can help characterise a patient’s tumour and identify the most suitable treatment course on a case-by-case basis.”
With the rising need for validation of non-invasive liquid biopsies, researchers can now evaluate the concordance in mutation profiles from tumour tissue samples with INVIEW ONCOPANEL and from liquid biopsy samples with GATCLIQUID ONCOPANEL. Both cancer sets consist of more than 200 clinically actionable regions on 50 cancer-specific genes with strong predictive and prognostic potential. The targeted cancer-related genes include well-known tumour activators, tumour suppressors and biomarkers of drug resistance.
“By providing cost-efficient detection of mutations in key cancer drivers, we hope to draw the most meaningful molecular information out of invasive, but necessary tissue biopsies,” added Dr Benz. “With the ability to perform comparative studies on tumour tissue and plasma-based patient samples under diagnostic conditions, we also aim to contribute evidence to proof-of-concept studies that are needed to implement liquid biopsies in clinical settings.”
INVIEW ONCOPANEL, which is a standardised sample-to-data solution, applies proprietary protocols for low-input DNA extraction from precious formalin-fixed, paraffin-embedded (FFPE) or fresh tissue samples. Optimised workflows carried out on leading technologies consistently result in extraordinarily high sequence coverage, uniformity and sensitivity that are needed to profile solid tumours and support tailored treatment decisions with absolute confidence.
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).
