Description

Analysis Note

The biological activity is measured by its ability to chemoattract 8-10 day human T lymphocytes cultured in the presence of IL-2.

Physical form

Lyophilized from 30% acetonitrile and 0.1% trifluoracetic acid containing 0.5 mg of bovine serum albumin.

Biochem/physiol Actions

SDF-1/PBSF is a chemoattractant for T lymphocytes and monocytes, but not neutrophils. It is highly conserved between species, with only one amino acid substitution between the human and mouse proteins.

SDF-1/PBSF, a member of the α (CXC) chemokine family, is a chemoattractant for T lymphocytes and monocytes, but not neutrophils. SDF-1α and SDF-1β (together also known as SDF-1/PBSF) are encoded by a single gene and arise by alternative splicing. The two proteins are identical except for the four amino acid residues that are present in the C-terminal of SDF-1β and absent from SDF-1α. SDF-1/PBSF is highly conserved between species, with only one amino acid substitution between the human and mouse proteins.
