 Q&A
Q:

I asks for the composition of the buffer for item CSB-EP018986HU. I need to know every component of the buffer.

A:
Very nice to receive your inquiry.
The buffer is as below: 10 mM Tris-HCl, 1 mM EDTA, pH8.0. As for the final concentration of glycerol, in principle, the final concentration from 5% to 50% are all OK, which may influence storage time.
If glycerol content is higher, relatively speaking, protein storage time will be longer. However, it all depend on your decision, adding glycerol or not adding glycerol, adding how much glycerol.
Q:

We are interested in several small units of many different products.  However,we are only interested in products with a GST tag.  For those listed below that have a His tag, what is the expense and time associated with getting these in a GST tag?   CSB-EP018986HU His

Target Background

Function
(From Uniprot)
Converts arachidonate to prostaglandin H2 (PGH2), a committed step in prostanoid synthesis. Constitutively expressed in some tissues in physiological conditions, such as the endothelium, kidney and brain, and in pathological conditions, such as in cancer. PTGS2 is responsible for production of inflammatory prostaglandins. Up-regulation of PTGS2 is also associated with increased cell adhesion, phenotypic changes, resistance to apoptosis and tumor angiogenesis. In cancer cells, PTGS2 is a key step in the production of prostaglandin E2 (PGE2), which plays important roles in modulating motility, proliferation and resistance to apoptosis.
