PromoKine offers a huge and continuously growing range of recombinant cytokines, chemokines, growth factors, soluble receptors and CD antigens (human, mouse, rat) that are produced in E. coli, yeast, insect, plant or mammalian cells. They are highly purified, biologically active and stable and are available in standard and very economic bulk sizes.
PromoKine has also extended its range of animal-free cytokines and growth factors that are produced in plants and are thus free of animal components, serum, endotoxins and antibiotics. These are also free of human, animal or bacterial infectious agents as well as other endogenous mammalian agents that might cause unwanted cell responses. They show very low proteolytic, pyrogenic and inflammatory activity compared to other commercially available proteins. Moreover, they retain proper eukaryotic folding and glycosylation, resulting in increased stability and biological activity.
In addition, PromoKine offers a huge variety of high-quality antibodies and ELISAs for the analysis of cytokines and growth factors as well as other interesting targets in cell biology.
The Optilab UT-rEX (UHPLC refractometer with EXtended range) is the first RI detector specifically designed for use with UHPLC systems using columns packed with small beads.
Using a combination of miniaturized components and cutting-edge semiconductor photodiode technology as well as proprietary computer algorithms, the UT-rEX presents a host of instrument firsts:
Besides UV, mass spectrometry, and evaporative light scattering, there has been no RI detector available for UHPLC applications until now. The linearity of the UT-rEX over a wide concentration range coupled with its sensitivity to samples that are not UV active, make it an exciting addition to UHPLC.
Considering the extremely small peak volumes of UHPLC, band broadening in the UT-rEX is kept to the absolute minimum, at less than 4 µL, as compared to 20-40 µL or more from other RI detectors. As a result, the superior resolution from UHPLC columns and instruments will not be compromised with the UT-rEX RI detector.
In addition, the instrument has no range or gain settings. The full range of instrument detection is always present, and the full sensitivity exists over the entire range. The small flow cell and proprietary temperature regulation enable stable RI baselines and signals which further enhance the detector’s sensitivity.
The new Optilab UT-rEX can be operated below ambient temperatures as easily as above ambient. No hassle temperature control can be programmed down to 4°C or as high as 50°C. The Optilab UT-rEX is compatible with all UHPLC systems.

PeproGrow-1 is protein-free, has a chemically defined composition, and does not contain any animal-derived materials. It is intended specifically to be used with DMEM/F12 basal media (Invitrogen catalog # 10565*) and contains enough material to supplement 10L of media.
The PromoCell MSC Growth Medium DXF eliminates the risks of using traditional FCS-containing MSC media and this innovative formulation provides significant benefits.
Chemically defined and humanized culture of MSC
Undifferentiated Mesenchymal Stem Cells (MSC) can be expanded in vitro to produce of large numbers of cells. For this expansion, traditional MSC culture media that contains special pre-qualified lots of fetal calf serum has been necessary. In addition to the serious ethical concerns relating to the use of FCS, this ill-defined component of animal origin is the major obstacle in providing consistent culture conditions and optimal performance of MSC.
The PromoCell MSC Growth Medium DXF eliminates the risks of using traditional FCS-containing MSC media. This innovative formulation provides significant benefits:
· Chemically defined
· Humanized: animal-free / xeno-free
· No adaption of cells required
· Outstanding expansion performance
· Maintenance of multipotency
· Supports primary isolation
· Standardized: minimal lot-to-lot variation
· Cost effective: more cells with less medium
For economical serum-free routine culture of MSC, the MSC Growth Medium DXF may be used in combination with bovine fibronectin as an ECM coating and our Detach Kit. For chemically defined culture conditions, the trypsin-containing DetachKit should be replaced by the Cell Dissociation Solution ACF. The use of human fibronectin and the Cell Dissociation Solution ACF completes the MSC Growth Medium DXF to yield a powerful animal-free and chemically defined complete culture system.
