蛋白结构(Molecular Characterization)

DNAM-1 Structure

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 27.9 kDa. The protein migrates as 36-50 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

电泳(SDS-PAGE)

DNAM-1 SDS-PAGE

Human DNAM-1, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).

 

活性(Bioactivity)-ELISA

DNAM-1 ELISA

Immobilized Human DNAM-1, His Tag (Cat. No. DN1-H52H6) at 2 μg/mL (100 μL/well) can bind Human CD155, Fc Tag (Cat. No. CD5-H5251) with a linear range of 3-128 ng/mL (QC tested).

Protocol

 

活性(Bioactivity)-BLI

DNAM-1 BLI

Loaded Human CD155, Mouse IgG2a Fc Tag, low endotoxin (Cat. No. CD5-H5254) on Protein A Biosensor, can bind Human DNAM-1, His Tag (Cat. No. DN1-H52H6) with an affinity constant of 0.57 μM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).

Protocol

 

活性(Bioactivity)-FACS

DNAM-1 FACS

FACS assay shows that Human DNAM-1, His Tag (Cat. No. DN1-H52H6) can bind to 293T cell overexpressing human CD155. The concentration of DNAM-1 used is 3 μg/mL (Routinely tested).

Protocol

 

背景(Background)

DNAX accessory molecule 1 (DNAM-1), a single-pass type I membrane protein, is also known as CD226 antigen and platelet and T cell activation antigen 1 (PTA1), which contains 2 Ig-like C2-type (immunoglobulin-like) domains. DNAM-1 is a ~65 kDa glycoprotein expressed on the surface of natural killer cells, platelets, monocytes and a subset of T cells. DNAM-1 mediates cellular adhesion to other cells bearing its ligands, CD112 and CD155, and cross-linking DNAM-1 with antibodies causes cellular activation. Furthermore, DNAM-1 can interact with PVR and PVRL2.
