Specifications

Human GRO beta is a member of the CXC family of chemokines and promotes neutrophil and basophil chemotaxis and degranulation. GRO-beta like GRO-alpha specifically inhibits growth factor-stimulated proliferation of capillary endothelial cells in a dose-dependent manner. Human GRO-beta is a 7.9kD protein containing 73 amino acid residues.
Catalog #	G8975-23
Source	E.coli
Form	The sterile filtered solution was lyophilized without additives.
Stability	The lyophilized protein is stable for few weeks at room temperature, but best stored at -20°C. Reconstituted human GRO-beta should be stored in working aliquots at -20°C.
Purity	98% by SDS-PAGE and HPLC analyses.
Endotoxin	0.1ng/ug (1EU/ug).
Reconstitution	We recommend a quick spin followed by reconstitution in water to a concentration of 0.1-1mg/ml. This solution can then be diluted into other aqueous buffers and stored at 4°C for 1 week or -20°C for future use.
Biological Activity	Determined by its ability to chemoattract CXCR2 transfected 293 cells using a concentration range of 10-100ng/ml.
