Specifications

Chemokine SDF-1 is highly conserved among species and belongs to a large family of small, structurally related cytokines. It is a chemoattractant for T lymphocytes, monocytes, and hemopoietic stem cells and is constitutively expressed in bone-marrow-derived stromal cells. Recent reports indicate that SDF-1 is the ligand for LESTR/fusin and prevents infection by T-cell-line-adapted HIV-1. SDF-1a and SDF-1b, are generated by alternative RNA splicing of transcripts encoded by a single gene. SDF-1a differs from SDF-1b by four C-terminal amino acid residues absent in SDF-1a. As yet, no functional differences have been reported.
Catalog #S7975-64
Stromal Cell-Derived Factor-1beta (SDF1b) is a recently discovered protein belonging to the a-chemokine (C-X-C) family of cytokines. Murine SDF1b is an 8.5kD protein containing 72 amino acid residues.
Source E. coli
Form Lyophilized protein without additives.
Stability Lyophilized SDF1b, though stable at room temperature, is best stored desiccated below 0°C. Reconstituted human SDF1b should be stored in working aliquots at -20°C.
Purity 98% by SDS-PAGE and HPLC analyses.
Endotoxin 0.1ng/ug
Reconstitution Lyophilized SDF1b is soluble in water and most aqueous buffers. The lyophilized protein can be reconstituted in water to a concentration of 0.1-1mg/ml. It is recommended that further dilutions be made into buffer containing carrier protein or medium containing serum.
Biological Activity Determined by its ability to chemoattract human monocytes using a concentration range of 50-100ng/ml
Concentration Range for most in vitro applications 0.1-1mg/ml
