Recombinant Rat CXCL3/CINC-2 beta Protein Summary

Product Specifications

Purity
>97%, by SDS-PAGE under reducing conditions and visualized by silver stain
Endotoxin Level
<0.10 EU per 1 μg of the protein by the LAL method.
Activity
Measured by its ability to induce myeloperoxidase release from cytochalasin B-treated human neutrophils. Schröder, J.M. et al. (1987) J. Immunol. 139:3474. The ED50 for this effect is 3-6 µg/mL. Measured by its ability to chemoattract BaF3 mouse pro‑B cells transfected with human CXCR2. The ED50 for this effect is 5-25 ng/mL.

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: CXCL3/GRO gamma/CINC-2/DCIP-1

The rat chemokines CINC (cytokine-induced neutrophil chemoattractant)-1, CINC-2 alpha, CINC-2 beta and CINC-3 (also named MIP-2) constitute a group of rat CXC chemokines that show significant sequence similarity to human GROs and mouse MIP-2 but not IL-8. CINC-2 alpha, CINC-2 beta were originally purified as novel neutrophil chemoattractants from the conditioned medium of rat granulation tissue which also contained CINC-1 and CINC-3. Based on amino acid (aa) sequence analysis of the purified CINC-2 alpha protein and sequencing of the CINC-2 beta cDNA clone, both mature CINC-2 alpha and CINC-2 beta were shown to contain 68 aa residues. The aa sequences of the two CINC-2 proteins are identical except for three carboxy-terminal residues. CINC-2 beta cDNA encodes a 100 aa residue precursor protein with a 32 aa residue signal peptide that is removed to yield the mature secreted protein. At the protein sequence level, mature CINC-2 proteins are 63% identical to CINC-1 and 80% identical to CINC-3. CINC-2 proteins represent the major chemokines purified from conditioned medium of granulation tissue or LPS-induced inflammatory exudate. Other cell types known to produce CINC-2 proteins include activated macrophages and fibroblasts.

Recombinant and natural CINC-2 proteins have been shown to be specific neutrophil chemoattractants both in vivo and in vitro. On the basis of cross-desensitization results of the various CINC proteins, it has been postulated that rat neutrophils have at least two classes of CINC receptors: a class of CINC-3-specific receptor as well as a second common receptor shared by all CINCs.
