Description
Accession
P50231
Source
Optimized DNA sequence encoding Rat RANTES mature chain was expressed in ECOLI. Recombinant Rat C-C motif chemokine 5 encodes amino acid residues 25-92.
Molecular weight
Recombinant RANTES migrates as an approximately 7 kDa protein under reducing conditions in SDS-PAGE.
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
Determined by its ability to chemoattract rat peritoneal macrophages using a concentration range of 50.0-100.0 ng/ml.
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
RANTES was Lyophilized from PBS, pH 7.2.
Sequence
SPYGSDTTPC CFAYLSLALP RAHVKEYFYT SSKCSNLAVV FVTRRNRQVC ANPEKKWVQE YINYLEMS
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 product can be stored in working aliquots at 2° - 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.
