GRO-alpha/CXCL1 Protein, Human (His)

Customer Review

Based on 1 Customer Validation

GRO-alpha/CXCL1 protein attracts neutrophils and potentially contributes to inflammation through autocrine effects on endothelial cells. Processed forms of GRO-alpha, including GRO-alpha(4-73), GRO-alpha(5-73), and GRO-alpha(6-73), exhibit 30-fold greater chemotactic activity than the full-length protein. GRO-alpha/CXCL1 Protein, Human (His) is the recombinant human-derived GRO-alpha/CXCL1 protein, expressed by E. coli , with N-6*His labeled tag.

Biological Activity

Description

GRO-alpha/CXCL1 protein attracts neutrophils and potentially contributes to inflammation through autocrine effects on endothelial cells. Processed forms of GRO-alpha, including GRO-alpha(4-73), GRO-alpha(5-73), and GRO-alpha(6-73), exhibit 30-fold greater chemotactic activity than the full-length protein. GRO-alpha/CXCL1 Protein, Human (His) is the recombinant human-derived GRO-alpha/CXCL1 protein, expressed by E. coli , with N-6*His labeled tag.

Background

GRO-alpha/CXCL1 protein exhibits chemotactic activity for neutrophils and may play a role in inflammation, exerting its effects on endothelial cells in an autocrine fashion. In vitro studies indicate that processed forms of GRO-alpha, namely GRO-alpha(4-73), GRO-alpha(5-73), and GRO-alpha(6-73), display a significantly enhanced chemotactic activity, being 30-fold higher compared to the full-length protein.

Verified Bioactivity

Measured in a cell proliferation assay using HUVEC. The ED50 for this effect is 0.8611 ng/mL, corresponding to a specific activity is 1.16×106 units/mg.
