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

• Cat.No.: CD276-2002HAF555
• 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 human IgG1 was expressed in CHO cell.

Specification

• Species: Human
• Source: CHO
• Tag: Fc
• Protein Length: 29-245 a.a.
• Description: The protein encoded by this gene belongs to the immunoglobulin superfamily, and thought to participate in theregulation of T-cell-mediated immune response. Studies show that while the transcript of this gene isubiquitously expressed in normal tissues and solid tumors, the protein is preferentially expressed only in tumortissues. Additionally, it was observed that the 3" UTR of this transcript contains a target site for miR29microRNA, and there is an inverse correlation between the expression of this protein and miR29 levels, suggestingregulation of expression of this gene product by miR29. Alternatively spliced transcript variants encodingdifferent isoforms have been found for this gene.
• Form: Lyophilized
• Bio-activity: Measured by its ability to inhibit anti-CD3-induced proliferation of stimulated human T cells.
• Molecular Mass: 49 kDa (monomer)
• AA Sequence: Leu29-Pro245
• Endotoxin: < 0.06 EU/ μg as determined by LAL test.
• Purity: > 98 % by SDS-PAGE under reducing conditions.
• Characteristic: Disulfide-linked homodimer
  Labeled with Alexa Fluor 555 via amines
  With an excitation and emission maximum of 555/565 nm, Alexa Fluor 555 can be efficiently excited using a 543 nm He-Ne laser line and detected under standard TRITC/Cy3 filters.
