Official Symbol

TNFSF8

Product Overview

Recombinant Human TNFSF8 protein(AA Gln 63-Asp 234)(Accession # P32971-1) is expressed from human 293 cells (HEK293). This protein carries a polyhistidine tag at the N-terminus.

Expression System

HEK293

Species

Human

Tag

N-His Tag

Form

Lyophilized from sterile PBS, pH7.4, 10% trehalose.

Molecular Mass

This protein carries a polyhistidine tag at the N-terminus. The protein has a calculated MW of 21.5 kDa. The protein migrates as 30-40 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Protein length

Gln 63-Asp 234

Endotoxin

Less than 0.01 EU per ug by the LAL method.

Purity

>90% as determined by SDS-PAGE.

Storage

For long term storage, the product should be stored at lyophilized state at -20°C or lower. Please avoid repeated freeze-thaw cycles. This product is stable after storage at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.

Reconstitution

It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4ºC before opening to recover the entire contents.

SDS-PAGE

Human CD30 Ligand, His Tag, low endotoxin on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

Bioactivity-ELISA 1

Immobilized Human CD30, Fc Tag at 2 ug/mL (100 uL/well) can bind Human CD30 Ligand, His Tag, low endotoxin with a linear range of 0.039-0.313 ug/mL.

Bioactivity-ELISA 2

Immobilized Human CD30 Ligand, His Tag, low endotoxin at 2 ug/mL (100 uL/well) can bind Human CD30, Llama IgG2b Fc Tag, low endotoxin with a linear range of 0.6-10 ng/mL.

Bioactivity-BLI 1

Loaded Biotinylated Human CD30, Avitag,His Tag on SA Biosensor, can bind Human CD30 Ligand, His Tag, low endotoxin with an affinity constant of 132 nM as determined in BLI assay (ForteBio Octet Red96e).

Bioactivity-FACS 1

FACS analysis shows that Human CD30 Ligand, His Tag, low endotoxin can bind to K562-CD30 cells surface CD30. The concentration of Human CD30 Ligand is 3 ug/mL.

Bioactivity-FACS 2

FACS analysis shows that the binding of Human CD30 Ligand, His Tag, low endotoxin 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 ug/mL. The IC50 is 0.2401 ug/mL.
