别名:   CXCL12 PBSF Stromal-Cell Derived Factor-1

产品名称

Biochem/physiol Actions

SDF-1 alpha and beta are stromal derived CXC chemokines, and signal through the CXCR4 receptor. Recombinant rat SDF-1b is an 8.4 kDa protein containing 72 amino acid residues.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

Physical form

Lyophilized with no additives.

General description

SDF-1 alpha and beta are stromal derived CXC chemokines, and signal through the CXCR4 receptor. SDF-1alpha and beta chemoattract B and T cells, and have been shown to induce migration of CD34+ stem cells. Additionally, the SDF-1 proteins exert HIV suppressive activity in cells expressing the CXCR4 receptor. Recombinant rat SDF-1b is an 8.4 kDa protein containing 72 amino acid residues.
