This protein carries a human IgG1 Fc tag at the N-terminus.
The protein has a calculated MW of 74.7 kDa. The protein migrates as 120-150 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Human CD40 Ligand Protein, Fc Tag, premium grade on SDS-PAGE under non-reducing (NR) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).
The purity of Human CD40 Ligand Protein, Fc Tag, premium grade (Cat. No. CDL-H5269) is more than 90% and the molecular weight of this protein is around 140-180 kDa verified by SEC-MALS.
Human CD40 Ligand Protein, Fc Tag, premium grade (Cat. No. CDL-H5269) stimulates secretion of IL-6 by human B cells. The ED50 for this effect is 9.68-11.48 ng/mL in the presence of 5 ng/mL of Recombinant Human IL‑4 (Routinely tested).
Neutralization assay shows that the cytokine secretion effect of Human CD40 Ligand Protein, Fc Tag, premium grade (Cat. No. CDL-H5269) was inhibited by increasing concentration of anti-CD40L mAb. The concentration of CD40L used is 50 ng/mL. The EC50 is 0.051-0.058 μg/mL (Routinely tested).
FACS analysis shows that Human CD40 Ligand Protein, Fc Tag, premium grade (Cat. No. CDL-H5269) can bind to 293T-CD40 cells surface CD40. The concentration of Human CD40 Ligand is 0.3 μg/mL (Routinely tested).
Immobilized Human CD40 Protein, His Tag (Cat. No. CD0-H5228) at 1 μg/mL (100 μL/well) can bind Human CD40 Ligand Protein, Fc Tag, premium grade (Cat. No. CDL-H5269) with a linear range of 0.2-3 ng/mL (QC tested).
