Active Recombinant Human CD276 Protein, MIgG2a mFc-tagged, Alexa Fluor 555 conjugated

• Cat.No.: CD276-2001HAF555
• Product Overview: The Alexa Fluor 555 conjugated extracellular domain of human B7-H3 (NP_079516.1) (Leu29-Pro245) is fused to the N-terminus of the Fc region of mouse IgG2a.

Specification

• Description: The protein encoded by this gene belongs to the immunoglobulin superfamily, and thought to participate in the regulation of T-cell-mediated immune response. Studies show that while the transcript of this gene is ubiquitously expressed in normal tissues and solid tumors, the protein is preferentially expressed only in tumor tissues. Additionally, it was observed that the 3" UTR of this transcript contains a target site for miR29 microRNA, and there is an inverse correlation between the expression of this protein and miR29 levels, suggesting regulation of expression of this gene product by miR29. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
