MABSol? Biotinylated Mouse PD-L1, Fc,Avitag (PD1-M82F5) is expressed from human HEK293 cells. It contains AA Phe 19 - Thr 238 (Accession # NP_068693).
Predicted N-terminus: Phe 19
This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag (Avitag?).
国产视频appThe protein has a calculated MW of 53.2 kDa. The protein migrates as 65-85 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Biotinylation of this product is performed using Avitag? technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
The biotin to protein ratio is 0.5-1国产视频app as determined by the HABA assay.
国产视频appLess than 1.0 EU per μg by the LAL method.
国产视频app>95% as determined by SDS-PAGE.
国产视频appLyophilized from 0.22 μm filtered solution in Tris?with?Glycine,?Arginine?and?NaCl,?pH7.5. Normally trehalose is added as protectant before lyophilization.

Biotinylated Mouse PD-L1, Fc,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Immobilized Biotinylated Mouse PD-L1, Fc,Avitag (Cat. No. PD1-M82F5) at 1 μg/mL (100 μL/well) on streptavidin precoated (0.5 μg/well) plate, can bind Mouse PD-1, Mouse IgG2a Fc Tag (Cat. No. PD1-M52A4) with a linear range of 5-39 ng/mL (QC tested).
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.
