特異性Ab33580 is highly specific to MAP 2a, b and c expressed in dendrites and cell bodies of neurons. It recognizes MAP2a and MAP2b (~280kD doublet) and MAP2c (70kD). It shows no crossreactivity with other MAPs, tau and tubulin.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 - 2 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
Use a concentration of 1 - 2 µg/ml. Perform heat mediated antigen retrieval before commencing the IHC protocol.
Use a concentration of 1 - 2 µg/ml. Predicted molecular weight: 199 kDa.
Use at an assay dependent concentration.
機能The exact function of MAP2 is unknown but MAPs may stabilize the microtubules against depolymerization. They also seem to have a stiffening effect on microtubules.
配列類似性Contains 3 Tau/MAP repeats.
翻訳後修飾Phosphorylated at serine residues in K-X-G-S motifs by MAP/microtubule affinity-regulating kinase (MARK1 or MARK2), causing detachment from microtubules, and their disassembly (By similarity). MAP2A/c is phosphorylated. Phosphorylated upon DNA damage, probably by ATM or ATR. Isoform MAP2c is phosphorylated by FYN at Tyr-67.
