Recombinant Human GASP-1/WFIKKNRP Protein (His Tag)

WAP , kazal , immunoglobulin , kunitz and NTR domain-containing protein 2 , also known as Growth and differentiation factor-associated serum protein 1 , WAP , follistatin , immunoglobulin , kunitz and NTR domain-containing-related protein , WFIKKN-related protein , WFIKKN2 and GASP1 , is a secreted protein that belongs to the WFIKKN family. WFIKKN2 contains two BPTI/Kunitz inhibitor domains , one Ig-like C2-type (immunoglobulin-like) domain , one Kazal-like domain , one NTR domain and one WAP domain. WFIKKN2 is primarily expressed in ovary , testis and brain , but not in liver. In fetal tissues , it is primarily expressed in brain , skeletal muscle , thymus and kidney. WFIKKN2 is a protease-inhibitor that contains multiple distinct protease inhibitor domains. It probably has serine protease-and metalloprotease-inhibitor activity. It inhibits the biological activity of mature myostatin , but not activin. WFIKKN2 protein binds mature GDF8/myostatin and myostatin propeptide and inhibits the biological activity of myostatin.

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
