Human SDF-1 alpha Recombinant, Biotinylated
Categories: Biotinylated proteinsCXC chemokines$160.00 – $3,500.00
Description
Accession
P48061
Source
Optimized DNA sequence encoding Human Stromal Cell-Derived Factor-1 alpha mature chain was expressed in Escherichia Coli. SDF-1A was further labeled by Biotin for detection by Avidin conjugated secondary probes
Molecular weight
Native human SDF-1 alpha, generated by the proteolytic removal of the signal peptide and propeptide,the molecule has a calculated molecular mass of approximately8 kDa. Recombinant SDF-1 alpha is a monomer protein consisting of69 amino acid residue subunits, migrates as an approximately8 kDa protein under non-reducing and reducing conditions in SDS-PAGE.
Purity
>97%, as determined by SDS-PAGE and HPLC

Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Presentation
Recombinant SDF-1 alpha was lyophilized from a 0.2μm filtered PBS, pH.4.
Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage
The lyophilized protein is stable for at least 2 years from date of receipt at -20° C. Upon reconstitution, this cytokine can be stored in working aliquots at2° -8° 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.
