Q&A and Customer Reviews


For item CSB-YP026244HU, would you please verify the buffer? We need a product without Imidazole.

Thanks for your inquiry.
When separating and purifying the protein, we use imidazole for elution. We can remove the imidazole as much as possible by dialysis, but we can't guarantee that there is no residue at all.
If you care about imidazole, please remark this request when sending the PO and we will try to remove the imidazole by dialysis as much as possible.
(We generally use a concentration of 200 mM - 500 mM imidazole to elute, which should be removed after dialysis.)
Please do not hesitate to contact us if you have further questions. Nice day.

I am interested in this protein but I'm wondering if it’s possible to obtain the elute in 20% glycerol instead of 50%? If this is possible, can you please tell me the size and cost?

Thanks for your inquiry. CSB-YP026244HU Recombinant Human Yorkie homolog(YAP1)
The delivery form is liquid. The storage buffer is 20 mM Tris-HCl, 0.5M NaCl, pH 8.0, 20% glycerole.
We could satisfy the your requirement for the glycerole content. Any more questions, feel free to contact us.
