Active Recombinant Human CD40, Fc Chimera

• Cat.No.: CD40-493H
• Product Overview: Recombinant Human CD40 encoding the signal peptide and extracellular domain of human CD40 (aa 1-193) was fused to the Fc region of human IgG1 (aa 90-330). The chimeric protein was expressed in modifiedHuman 293 cells.

Specification

• Cat. No.: CD40-493H
• Description: CD40 (TNFRSF5, CD40L Receptor) is a type I membrane protein and a member of the TNF receptor family. CD40 is expressed on B cells, monocytes, dendritic cells, endothelial cells, epithelial cells and B cell lymphomas and carcinomas. CD40 activates mulitple signalling pathways and can promote cell survival through up-regulation of the expression of genes encoding anti-apoptopic proteins.
• Source: Human 293 cells.

• Molecular Mass: Under reducing conditions CD40 (173aa) – Fc Chimera migrates as a broad band between 50 and 65 kDa on SDS-PAGE due to post-translational modifications, in particular glycosylation.
• pI: CD40 (173aa) – Fc Chimera separates into a number of glycoforms with an observed pI between 5.5 and 9.0 in 2D PAGE due to post-translational modifications, in particular glycosylation.
• % Carbohydrate: Purified CD40 (173aa) - Fc Chimera consists of 5 to 30% carbohydrate by weight.
• Glycosylation: CD40 (173aa) – Fc Chimera contains N-linked oligosaccharides and may contain O-linked oligosaccharides.
• Purity: >95%, as determined by SDS-PAGE and visualized by Coomassie Brilliant Blue.
• Formulation: When reconstituted in 0.5 ml sterile phosphate-buffered saline, the solution will contain 1% human serum albumin (HSA) and 10% trehalose.
• Reconstitution: It is recommended that 0.5 ml of sterile phosphate-buffered saline be added to the vial.
• Storage: Lyophilized products should be stored at 2 to 8°C.
• Activity: The ED₅₀of CD40 (173aa) – Fc Chimera is typically 1.0-1.5 ug/ml as measured by its ability to neutralize CD40 ligand mediated proliferation of T47-D cells.
