Recombinant Rat GRO/CXCL1 (rRtGRO/CXCL1)

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/KC is a 7.8 kDa protein consisting of 72 amino acids including the 'ELR' motif common to the CXC chemokine family that bind to CXCR1 or CXCR2.

Product Specifications

CAS Number

9000-83-3

Endotoxin

Less than 1EU/g of rRtGRO/CXCL1 as determined by LAL method.

Purity

>97% by SDS-PAGE and HPLC analyses.

Bioactivity

Fully biologically active when compared to standard. Determined by its ability to chemoattract rat neutrophils using a concentration range of 10.0-100.0 ng/ml, corresponding to a Specific Activity of > 1 x 104 IU/mg.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at <-20C. Further dilutions should be made in appropriate buffered solutions.

Molecular Weight

7.8 kDa, a single, non-glycosylated polypeptide chain containing 72 amino acids.

Storage Conditions

This lyophilized preparation is stable for several weeks at 2-8C, but should be kept at -20C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20C to -70C. Avoid repeated freeze/thaw cycles.
