Specificity / Sensitivity

MAP1B Antibody recognizes endogenous levels of total MAP1B protein.

Species Reactivity:

Human, Mouse, Rat

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val1570 of human MAP1B protein. Antibodies are purified by peptide affinity chromatography.

Background

Microtubule-associated protein 1B (MAP1B) is a member of the high molecular weight microtubule binding phosphoprotein family, along with MAP1A (1). MAP1B is highly expressed in neurons, predominantly during development, where it regulates axonal guidance and elongation through its influence on microtubule dynamics (1,2). In mature neurons, MAP1B plays a role in regulation and structure of dendritic spines in glutamatergic synapses. MAP1B deficient neurons have been shown to display structural presynaptic deficiencies, including a decrease in density at synaptic terminals and disruption of synaptic vesicle fusion events (2). Mutations in MAP1B have been linked to developmental disorders affecting cognitive ability through a deficit in white matter and compromised axons (3).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
