小鼠基質細胞源因子-1α|Murine SDF-1alpha (CXCL12)

Synonyms :

Stromal-Cell Derived Factor-1, CXCL12, PBSF

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 murine SDF-1alpha is a 7.9 kDa protein containing 68 amino acid residues.

Catalog #:

250-20A

Source :

E.coli

Stability :

The lyophilized protein is stable for at least 2 years from date of receipt at -20⁰C. Reconstituted SDF-1 alpha is stable for at least 3 months when stored in working aliquots with a carrier protein at -20⁰C. Avoid repeated freeze/thaw cycles

Purity :

Greater than 98% by SDS-PAGE gel and HPLC analyses.

Endotoxin Level :

Endotoxin level is less than 0.1 ng per µg (1EU/µg).

Biological Activity :

Determined by its ability to chemoattract human peripheral blood monocytes using a concentration of 50-100 ng/ml.
