High quality recombinant human Growth/differentiation factor 15 (GDF15) protein purified and refolded from E.coli. No contamination from related TGF beta family proteins, solving a huge problem for researchers in this field (Olsen,2017). Tested in a well-characterised SMAD2/3 activation assay to confirm no SMAD signalling.
***Beta launch*** Our brand new optimised R-spondin 1 (Qk006 RSPO1), is now available for beta testing. 50% off and a free 100ug unit of any of our growth factors if you provide feedback we can share with other scientists! Project co-funded by Innovate UK. FGF10 available now, Gremlin 1 and others available soon…
We use proprietary refolding technologies and protein purification techniques developed at the University of Cambridge to produce high quality growth factors in E.coli. By solving scientific challenges such as structural heterogeneity, poor stability and solubility and spurious interactions with other biomolecules,we provide you more reliable tools for stem cell and organoid culture.
You can order online and upload your PO, simply email Meena at orders@qkine.com or phone +44 (0) 1223 491486. We make it easy so you can concentrate on your science.
Well we don’t actually deliver everywhere by bike – unless you are in the middle of Cambridge, UK! We do ship for free to all UK, Europe and US labs and biotechs. Please email orders@qkine.com if you are outside this area and we’ll find the best way of getting your growth factors to you.
We work with our customers to support their science: we can reserve stock from batches you have validated or produce custom batches for bulk purchases. To find out more, please contact orders@qkine.com
Growth factor quality underpins success of your stem cell culture. We provide the highest purity protein, minimise batch-to-batch variation and provide batch-specific quality control data for all our recombinant proteins so you can concentrate on your science.
