GRO1/KC Mouse Recombinant (CXCL1)
Chemokine (C-X-C motif) ligand 1 (CXCL1) is a small cytokine belonging to the CXC chemokine family that was previously called GRO1 oncogene, Neutrophil-activating protein 3 (NAP-3) and melanoma growth stimulating activity, alpha (MSGA-a). It is secreted by human melanoma cells, has mitogenic properties and is implicated in melanoma pathogenesis. CXCL1 is expressed by macrophages, neutrophils and epithelial cells, and has neutrophil chemoattractant activity. CXCL1 plays a role in spinal cord development by inhibiting the migration of oligodendrocyte precursors and is involved in the processes of angiogenesis, inflammation, wound healing, and tumorigenesis. This chemokine elicits its effects by signaling through the chemokine receptor CXCR2. The gene for CXCL1 is located on human chromosome 4 amongst genes for other CXC chemokines.
| Description | KC Mouse Recombinant also known as N51 and GRO1 produced in E.Coli is a single,non-glycosylated, polypeptide chain containing 77 amino acids and having a molecular mass of approximately 8 kDa. The GRO-1 is purified by proprietary chromatographic techniques. |
| Protein Content | Protein quantitation was carried out by two independent methods 1. UV spectroscopy at 280 nm using the absorbency value of 0.03 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a standard solution of KC as a Reference Standard. |
| Synonyms | Growth-regulated alpha protein, CXCL1, Platelet-derived growth factor-inducible protein KC, Secretory protein N51, KC, Fsp, N51, gro, Gro1, Mgsa, Scyb1, chemokine (C-X-C motif) ligand 1. |
| Source | Escherichia Coli. |
| Amino Acid Sequence | RLATGAPIANELRCQ CLQTMAGIHL KNIQSLKVLP SGPHCTQTEV IATLKNGREA CLDPEAPLVQ KIVQKMLKGV PK. |
| Purity | >96% as determined by SDS-PAGE and HPLC |
| Formulation | Sterile Filtered White lyophilized (freeze-dried) powder. The protein was lyophilized with no additives. |
| Stability | The lyophilized form of the protein is stable at room temperature for 3 weeks and at -20°C for at least 2 years from the date of receipt. Upon reconstitution, the protein should be stored at 4°C for no more than 7 days. The protein is stable at -20°C for six months. For long term storage, please store at -80°C and the addition of a carrier protein (0.1% HSA or BSA) is recommended. Please prevent freeze-thaw cycles. |
| Biological Activity | The biological activity was determined by measuring the dose dependent mobilization of intracellular calcium (calcium flux) with human neutrophils. Significant calcium mobilization is observed with 50ng/mL of recombinant mouse KC (Specific Activity: 2 x 10000 units/mg). |
| Solubility | It is recommended to reconstitute the lyophilized GRO1 Recombinant in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
| Usage | LABORATORY RESEARCH USE ONLY. Not intended for diagnostic or therapeutic purposes. |
