表达区间及表达系统（Source）
Biotinylated Human Nectin-2, Fc,Avitag (CD2-H82F8) is expressed from human 293 cells (HEK293). It contains AA Gln 32 - Leu 360 (Accession # Q92692-2).
Predicted N-terminus: Gln 32
Request for sequence蛋白结构（Molecular Characterization）
This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 64.0 kDa. The protein migrates as 66 kDa under reducing (R) condition, and 130 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
偶联（Conjugate）
Biotin

Protocol
Immobilized Human PVRIG, Fc Tag (Cat. No. PVG-H5257) at 5 μg/mL (100 μL/well) can bind Biotinylated Human Nectin-2, Fc,Avitag (Cat. No. CD2-H82F8) with a linear range of 0.2-16 ng/mL (Routinely tested).
Protocol
Serial dilutions of TIGIT antibody antibody (1:2 serial dilutions, from 20 μg/mL to 0.0097 μg/mL) were added into Human TIGIT, Mouse IgG2a Fc Tag (Cat. No. TIT-H5253): Biotinylated Human Nectin-2, Fc,Avitag (Cat. No. CD2-H82F8) binding reactions. The assay was performed according to the above described protocol. Background was subtracted from data points before curve fitting.
