Product Information
Recombinant Human GROb/CXCL2
Synonyms: Growth Regulated Protein/Melanoma Growth Stimulatory Activity (MGSAb), CXCL2, MIP-2,
GRO2
Description: All three isoforms of GRO are CXC chemokines that can signal through the CXCR1 or
CXCR2 receptors. The GRO proteins chemoattract and activate neutrophils and basophils.
Recombinant human GROb is a 7.9 kDa protein consisting of 73 amino acids including the ‘ELR’ motif
common to the CXC chemokine family that bind to CXCR1 or CXCR2.
Source: E.coli
Purity: Greater than 98% by SDS-PAGE gel and HPLC analyses
Endotoxin level: Endotoxin level is less than 0.1 ng per mg (1EU/mg).
Formulation: Sterile filtered through a 0.2 micron filter. Lyophilized with no additives.
Reconstitution: Centrifuge the vial prior to opening. Reconstitute in water to a concentration of
0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and
stored at 4oC for 1 week or -20oC for future use.
Stability: The lyophilized protein is stable for a few weeks at room temperature, but best
stored at -20oC. Reconstituted GROb should be stored in working aliquots at -
20oC.
Biological Activity: Determined by its ability to chemoattract CXCR2 transfected 293 cells using a
concentration range of 10.0-100.0 ng/ml.
