蛋白结构(Molecular Characterization)

MAG / Siglec-4a Structure

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 81.1 kDa. The protein migrates as 100-115 kDa 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.

  1. -20°C to -70°C for 12 months in lyophilized state;
  2. -70°C for 3 months under sterile conditions after reconstitution.
 

电泳(SDS-PAGE)

MAG / Siglec-4a SDS-PAGE

Human MAG, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.

 

活性(Bioactivity)-SPR

MAG / Siglec-4a SPR

Human Nogo Receptor, His Tag (Cat. No. NOR-H52H3) capture on NTA-Series S sensor chip can bind Human MAG, Fc Tag (Cat. No. MAG-H5254) with an affinity constant of 2.21 μM as determined in a SPR assay (Biacore 8K) (Routinely tested).

Protocol

 

背景(Background)

Myelin-associated glycoprotein (MAG), a nervous system cell adhesion molecule, is an I-type lectin that binds to sialylated glycoconjugates, including gangliosides bearing characteristic structural determinants. Preferentially binds to alpha-2,3-linked sialic acid. Binds ganglioside Gt1b. Adhesion molecule that mediates interactions between myelinating cells and neurons by binding to neuronal sialic acid-containing gangliosides and to the glycoproteins RTN4R and RTN4RL2. Protection against apoptosis is probably mediated via interaction with neuronal RTN4R and RTN4RL2. In dorsal root ganglion neurons the inhibition is mediated primarily via binding to neuronal RTN4R or RTN4RL2 and to a lesser degree via binding to neuronal gangliosides. In cerebellar granule cells the inhibition is mediated primarily via binding to neuronal gangliosides. In sensory neurons, inhibition of neurite extension depends only partially on RTN4R, RTN4RL2 and gangliosides.
