Product Information
Description: Protosappanin A (PTA), an immune agent, is a major biphenyl compound isolated from Caesalpinia sappan L that inhibits the JAK2/STAT3-dependent inflammatory pathway by down-regulating the phosphorylation of JAK2 and STAT3.
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
