蛋白结构(Molecular Characterization)
This protein carries a mouse IgG2a Fc tag at the N-terminus.
The protein has a calculated MW of 46.5 kDa. The protein migrates as 55-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 0.1 EU per μg by the LAL method.
纯度(Purity)
>95% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

活性(Bioactivity)-ELISA
Immobilized Human CD30 Protein, His Tag at 2 μg/mL (100 μL/well) can bind Human CD30 Ligand Protein, Mouse IgG2a Fc Tag (Cat. No. CDL-H525b) with a linear range of 1-25 ng/mL (QC tested).
Protocol
活性(Bioactivity)-BLI
Loaded Biotinylated Human CD30 Protein, Avitag,His Tag (Cat. No. CD0-H82E6) on SA Biosensor, can bind Human CD30 Ligand Protein, Mouse IgG2a Fc Tag (Cat. No. CDL-H525b) with an affinity constant of 114 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
Protocol
活性(Bioactivity)-FACS
FACS analysis shows that Human CD30 Ligand Protein, Mouse IgG2a Fc Tag (Cat. No. CDL-H525b) can bind to K562-CD30 cells surface CD30. The concentration of Human CD30 Ligand is 0.1 μg/mL (Routinely tested).
Protocol
FACS analysis shows that the binding of Human CD30 Ligand Protein, Mouse IgG2a Fc Tag (Cat. No. CDL-H525b) to K562-CD30 cells surface CD30 was inhibited by increasing concentration of neutralizing anti-CD30 antibody. The concentration of Human CD30 Ligand used is 0.1 μg/mL. The IC50 is 0.2064 μg/mL (Routinely tested).
Protocol
背景(Background)
CD30 ligand (CD30L) and CD30 are interacting cellsurface glycoproteins that are members of the tumour necrosis factor (TNF) and tumour necrosis factor receptor
(TNFR) superfamilies. In humans, CD30L is expressed at high levels on activated T cells. There is conflicting evidence with regard to cell surface expression of CD30L on primary human B cells. An initial report of constitutive CD30L expression on peripheral blood B cells33 has not been substantiated.
