| Description : |
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. |
| Form : |
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant. |
| Bio-activity : |
Immobilized Human PD-L1 Protein, Tag Free at 1 μg/mL (100 μL/well) can bind Anti-PD-L1 Antibody, Human IgG1 with a linear range of 0.06-1 ng/mL. |
| Molecular Mass : |
The protein has a calculated MW of 25.2 kDa. The protein migrates as 30-35 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation. |
| Endotoxin : |
Less than 1.0 EU/μg by the LAL method/rFC method. |
| Purity : |
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS. |
| Storage : |
This product is stable after storage at: -20 to -70 centigrade for 12 months in lyophilized state; -70 centigrade for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower. Please avoid repeated freeze-thaw cycles. |
| Reconstitution : |
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 μg/μL. Centrifuge the vial at 4 centigrade before opening to recover the entire contents. |
