GRO b Mouse

GRO-Beta Mouse Recombinant (CXCL2)

GRO-Beta Mouse Recombinant also caled mouse MIP-2 produced in E.Coli is a single,non-glycosylated, polypeptide chain containing 73 amino acids and having a molecular mass of 7849 Dalton.
The CXCL2 is purified by proprietary chromatographic techniques.

Accession

P10889

Amino acid sequence

The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Val-Ala-Ser.

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 >5 ng/ml (corresponding to a Specific Activity of 200,000IU/mg) of recombinant mouse MIP-2.

Formulation

The protein was lyophilized with no additives.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Protein content

Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 0.015 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 GRO-b as a Reference Standard.

Purity

Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility

It is recommended to reconstitute the lyophilized GRO-beta Mouse in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source

Escherichia Coli.

Stability

Lyophilized CXCL2 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution CXCL2 should be stored at 4oC between 2-7 days and for future use below -18oC. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
