INTRODUCTION
QC & Assay Protocol
Citation & Background
  • Synonym
    PD-L1,CD274,B7-H1,PDCD1L1,PDCD1LG1
  • Source
    Canine PD-L1, Fc Tag (PD1-C52H3) is expressed from human 293 cells (HEK293). It contains AA Phe 19 - His 238 (Accession # E2RKZ5-1).
    Predicted N-terminus: Phe 19

  • Molecular Characterization
    Online(Phe 19 - His 238) E2RKZ5-1

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 51.4 kDa. The protein migrates as 65-80 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • 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:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
Canine PD-L1, Fc Tag (Cat. No. PD1-C52H3) SDS-PAGE gel

Canine PD-L1, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

Loaded Canine PD-1, His Tag (Cat. No. PD1-C52H9) on HIS1K Biosensor, can bind Canine PD-L1, Fc Tag (Cat. No. PD1-C52H3) with an affinity constant of 85 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).

Protocol
  • Background
    Programmed cell death 1 ligand 1 (PDL1) is also known as B7-H, B7H1, MGC142294, MGC142296, PD-L1, PDCD1L1 and PDCD1LG1,which is a member of the growing B7 family of immune molecules and is involved in the regulation of cellular and humoral immune responses.PDL1 is a cell surface immunoglobulin superfamily with two Ig-like domains within the extracellular region and a short cytoplasmic domain. This protein is broadly expressed in the majority of peripheral tissues as well as hematopoietic cells. Interaction between PDL1 and its receptors belonging to the CD28 family of molecules provide both stimulatory and inhibitory signals in regulating T cell activation and tolerance. PDL1 may inhibit ongoing T-cell responses by inducing apoptosis and arresting cell-cycle progression.
