Recombinant Mouse Common gamma Chain Fc Chimera Protein, CF Summary

Product Specifications

Purity

>90%, by SDS-PAGE under reducing conditions and visualized by silver stain.

Endotoxin Level

<1.0 EU per 1 μg of the protein by the LAL method.

Activity

Measured by its ability to inhibit the IL-2-dependent proliferation of MO7e human megakaryocytic leukemic cells. The ED₅₀ for this effect is 2-10 µg/mL in the presence of 30 µg/mL of soluble IL-2 R beta and 10 ng/mL of recombinant human IL-2.

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: Common gamma Chain/IL-2 R gamma

The gamma chain of the high affinity functional mouse IL-2 receptor complex belongs to the hematopoietin receptor family. Mouse Common gamma Chain is a 369 amino acid residue protein consisting of a 22 residue signal sequence, a 241 residue extracellular domain, a 21 residue transmembrane domain and an 85 residue cytoplasmic domain. Although Common gamma Chain by itself does not bind IL-2 with any appreciable affinity, it is required for IL-2 receptor signaling. Besides IL-2, the gamma chain has been shown to be a component of the functional receptor complexes for IL-4, IL-7, IL-9 and IL-15. IL-2 R gamma is also designated the common gamma chain ( gamma _c) (1, 2). The site of molecular defects in human X-linked SCID (severe combined immunodeficiency) has been mapped to the human common gamma gene.
