Recombinant

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 Rat GRO-β/MIP-2 is a 7.9 kDa protein consisting of 73 amino acids, including the ‘ELR’ motif common to the CXC chemokine family that binds to CXCR1 or CXCR2.

Biological Activity

Determined by its ability to chemoattract rat neutrophils using a concentration range of 10.0–100.0 ng/ml.

Endotoxin

Endotoxin level is <0.1 ng/μg of protein (<1EU/μg).

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1–1.0 mg/ml. Do not vortex. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at –20°C to –80°C.

Storage/Expiration
