Rat Stromal Cell-Derived Factor-1 beta Recombinant


accession Q9QZD1

Source Optimized DNA sequence encoding Rat Stromal Cell-Derived Factor-1 beta mature chain was expressed in Escherichia Coli.
Molecular weight NativeRat SDF-1 beta, generated by the proteolytic removal of the signal peptide and propeptide,the molecule has a calculated molecular mass of approximately kDa. Recombinant Rat SDF-1 beta is a monomer protein consisting of73 amino acid residue subunits, migrates as an approximately kDa protein under non-reducing and reducing conditions in SDS-PAGE.
Purity >97%, as determined by SDS-PAGE and HPLC
Biological Activity Determined by its ability to chemoattract human monocytes using a concentration range of-80 ng/ml.

Endotoxin Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than.1 ng/µg(1EU/µg).
Presentation Rat SDF-1 beta was lyophilized from a.2 μm filtered PBS solution pH7.5.
Reconstitution A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than.1 mg/mL. This solution can then be diluted into other buffers.
Storage The lyophilized protein is stable for at least years from date of receipt at -20° C. Upon reconstitution, this cytokine can be stored in working aliquots at° -° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
Usage This cytokine product is for research purposes only.It may not be used for therapeutics or diagnostic purposes.
