Protocol
Bioactivity-FACS
FACS analysis shows that Human CD30 Ligand Protein, His Tag (Cat. No. CDL-H524b) can bind to K562-CD30 cells surface CD30. The concentration of Human CD30 Ligand is 3 μg/mL (Routinely tested).
Protocol
FACS analysis shows that the binding of Human CD30 Ligand Protein, His Tag (Cat. No. CDL-H524b) to K562-CD30 cells surface CD30 was inhibited by increasing concentration of neutralizing anti-CD30 antibody. The concentration of Human CD30 Ligand used is 3 μg/mL. The IC50 is 0.2401 μg/mL (Routinely tested).

Background
(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.
