Biotinylated Human PD-L2 / B7-DC Protein (recommended for biopanning), Avi Tag (Avitag™)

内毒素:
Less than 1.0 EU per μg by the LAL method.

纯度:
>95% as determined by SDS-PAGE.

活性:
Measured by its binding ability in a functional ELISA against immobilized anti-PD-L2 mAb (human IgG1, 0.2μg/well). The linear is 3-50 ng/mL.

产品背景:
Programmed cell death 1 ligand 2 (PD-L2 or PDCD1 ligand 2) is also known as Butyrophilin B7-DC, CD antigen CD273, which belongs to the immunoglobulin superfamily or BTN/MOG family. The expression of PD-L2 is up-regulated by IFNG/IFN-gamma stimulation in monocytes and induced on dendritic cells grown from peripheral blood mononuclear cells with CSF2 and IL-4. PD-L2 Involved in the costimulatory signal, essential for T-cell proliferation and IFNG production in a PDCD1-independent manner. PD-L2 interaction with PDCD1 inhibits T-cell proliferation by blocking cell cycle progression and cytokine production.

产品描述:
This protein carries an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag. The protein has a calculated MW of 25.2 kDa. The protein migrates as 35-45 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation.
