Synonyms Small inducible cytokine A1, CCL1, T lymphocyte-secreted protein I-309, chemokine (C-C motif) ligand 1, P500, SISe, TCA3, I-309, SCYA1.
Description I-309 Human Recombinant produced in E.Coli is a single,non-glycosylated, polypeptide chain containing 74 amino acids and having a molecular mass of 8504 Dalton. The I-309 is purified by proprietary chromatographic techniques.
Uniprot Accesion Number P22362
Amino Acid SequenceThe sequence of the first five N-terminal amino acids was determined and was found to be Ser-Lys-Ser-Met-Gln.
Source Escherichia Coli.
Physical Appearance and Stability Lyophilized I-309 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CCL1 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Formulation and Purity The CCL1 protein was lyophilized with no additives. Greater than 99.0% as determined by
Application
Solubility It is recommended to reconstitute the lyophilized I-309 in sterile 18MO-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Biological Activity The Biological activity is calculated by its ability to chemoattract human T cells at 10-100ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg.
Shipping Format and Condition Lyophilized powder at room temperature.
