Product Overview
This rabbit polyclonal antibody recognizes myelin-associated glycoprotein (gene MAG) in human, mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 69.1 kDa, and the supplier reports an observed band at about 100 kDa.
Myelin-associated glycoprotein (MAG, Siglec-4) is a sialic acid-binding immunoglobulin-like lectin found on the inner membrane of myelin sheaths. It binds neuronal gangliosides and Nogo receptors to maintain axon–myelin contact and long-term axon integrity, and it is well known as an inhibitor of axon regeneration after central nervous system injury.

Validated Applications
| Western blot | 0.1–0.25 µg/mL (Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human, Mouse, Rat) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): rat brain tissue, mouse brain tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 8% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human cerebral cortex tissue, human cerebellum tissue, mouse cerebellum tissue, rat cerebellum tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Recombinant human MAG fragment (Glu34–Arg605), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places myelin-associated glycoprotein in the cell membrane and membrane raft. Tissue expression noted by UniProt (human): Both isoform 1 and isoform 2 are detected in myelinated structures in the central and peripheral nervous system, in periaxonal myelin and at Schmidt-Lanterman incisures. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
