Cat#:RP-2321R;Product Name:Recombinant Rat GRO a Protein;Synonym:Growth-regulated protein alpha, CXCL1, Melanoma growth stimulatory activity, MGSA, Neutrophil-activating protein 3, NAP-3, GRO-alpha(1-73), chemokine (C-X-C motif) ligand 1, GRO1, GROa, SCYB1, MGSA-a, MGSA alpha.;Description:CXCL1 Rat Recombinant produced in E.coli is a single,non-glycosylated, polypeptide chain containing 73 amino acids and having a molecular mass of 7.8 kDa. The Rat CXCL1 is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:APVANELRCQ CLQTVAGIHF KNIQSLKVMP PGPHCTQTEV IATLKNGREA CLDPEAPMVQ KIVQKMLKGV PK.;Purity:>97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:Determined by its ability to chemoattract rat neutrophils using a concentration range of 10-100ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg.;Formulation:Lyophilized from a 0.2μm filtered concentrated (1mg/ml) solution in 20mM PB, pH 7.4, and 150mM NaCl.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized CXCL1 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized CXCL1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CXCL1 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.;
