Product Overview

Recombinant Mouse Cd274 protein(AA Phe 19-Thr 238)(Accession # NP_068693) is expressed from human 293 cells (HEK293). This protein carries a polyhistidine tag at the C-terminus.

Expression System

HEK293

Species

Mouse

Tag

C-His Tag

Form

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

Molecular Mass

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 26.6 kDa. The protein migrates as 40-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Protein length

Phe 19-Thr 238

Endotoxin

Less than 1.0 EU per ug by the LAL method.

Purity

>95% 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

Mouse PD-L1, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

Bioactivity-BLI 1

Loaded Mouse PD-1, Fc Tag on ProteinA Biosensor, can bind Mouse PD-L1, His Tag with an affinity constant of 1.5 uM as determined in BLI assay (ForteBio Octet Red96e).

Bioactivity-SPR 1

Captured Mouse PD-1, Fc Tag on Protein A Chip can bind Mouse PD-L1, His Tag with an affinity constant of 2.16 uM as determined in SPR assay (Biacore T200).

Bioactivity-SPR 2

Captured Mouse PD-L1, His Tag on CM5 Chip via Anti-His antibody can bind Mouse PD-1, Fc Tag with an affinity constant of 1.37 uM as determined in SPR assay (Biacore T200).
