Human CD40L

• Catalog Number: orb2993921
• Category: Proteins
• Description: Recombinant Human CD40 Ligand is produced by our Mammalian expression system and the target gene encoding Met113-Leu261 is expressed with a mFc tag at the N-terminus.
• Conjugation: Unconjugated
• Tag: N-mFc
• Form/Appearance: Lyophilized from a 0.2 μm filtered solution of PBS, 1mM EDTA, pH 7.4.
• Reconstitution: Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
• Purity: SDS-PAGE: Greater than 90% as determined by reducing SDS-PAGE.
• UniProt ID: P29965
• MW: Predicted: 42.7 KDa. Observed: 50&90 KDa, reducing conditions
• Expression System: Human Cells
• Endotoxins: < 1 EU/µg as determined by LAL test.
• Biological Origin: Human
• Biological Activity: BLI: Loaded Anti-Human CD40L mAb-Fc(Cat#orb2993151) on AHC Biosensor, can bind Human CD40L-mFc(Cat#orb2993921) with an affinity constant of -3 nM as determined in BLI assay. (Regularly tested) Loaded Human CD40-His(Cat#orb2995146) on HIS1K Biosensor, can bind Human CD40L-mFc(Cat#orb2993921) with an affinity constant of 4.21 nM as determined in BLI assay. Loaded Cynomolgus CD40-His(Cat#orb2994787) on HIS1K Biosensor, can bind Human CD40L-mFc(Cat#orb2993921) with an affinity constant of 3.62 nM as determined in BLI assay.
