PF-4/CXCL4 Protein, Human (Biotinylated, His-Avi)

Wnt-10b protein is a signaling molecule that plays a key role in embryonic development and tissue homeostasis. It is involved in regulating cell proliferation, differentiation and migration. PF-4/CXCL4 Protein, Human (Biotinylated, His-Avi) is the recombinant human-derived PF-4/CXCL4 protein, expressed by E. coli , with C-Avi, N-His labeled tag. The total length of PF-4/CXCL4 Protein, Human (Biotinylated, His-Avi) is 70 a.a., with molecular weight of 13 kDa.

The PF-4/CXCL4 Protein, a member of the CXC chemokine family, is encoded by this gene. Released from the alpha granules of activated platelets in the form of a homotetramer, this chemokine exhibits high affinity for heparin and plays a crucial role in platelet aggregation. Beyond its involvement in platelet function, PF-4/CXCL4 is chemotactic for various cell types and serves as an inhibitor of hematopoiesis, angiogenesis, and T-cell function. Additionally, it demonstrates antimicrobial activity against Plasmodium falciparum. The gene displays biased expression, with elevated levels in the bone marrow (RPKM 14.3), spleen (RPKM 2.7), and one other tissue, underscoring its potential significance in various physiological contexts across multiple organs.

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from 0.22 μm filtered solution in 4mM HCl, pH 3.0. Normally 8% trehalose is added as protectant before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in 4 mM HCl (pH 3.0).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
