Produktbeschreibung

Format: Affinity-purified

Beschreibung: Gap-43 is thought to have an important role in development and plasticity because it is expressed at high levels in neuronal growth cones during development and during axonal regeneration (Benowitz and Routtenberg, 1997). There is also evidence from knockout animals that Gap-43 serves to amplify pathfinding signals from the growth cone (Strittmatter et al., 1995). Gap-43 is thought to mediate at least some of these effects via interaction with actin. Importantly, phosphorylation at Ser41 by protein kinase C (Catalog No. 1609-PKC) modulates the interaction of Gap-43 with actin (He et al., 1997) and may also affect neurotransmitter release during forms of plasticity like LTP (Hulo et al., 2002). Anti-Phospho Ser41 Gap-43 Western blot of rat cortex lysate showing specific immunolabeling of the ~50k Gap-43 protein phosphorylated at Ser41 (Control). The phosphospecificity of this labeling is shown in the second lane (lambda-phosphatase: (-Ptase). The blot is identical to the control except that it was incubated in (-Ptase (1200 units for 30 min) before being exposed to the GAP-43 Ser41 antibody. The immunolabeling of GAP-43 is completely eliminated by treatment with (-Ptase.

Spezifität: Specific for the ~50k Gap-43 protein phosphorylated at Ser41. In some tissues the antibody also recognizes a higher molecular weight protein that is also recognized by the pan Gap-43 antibody, that may be a Gap-43 aggregate or oligomer. Immunolableing is blocked by the phosphopeptide used as antigen but not by the corresponding dephosphopeptide. Immunolabeling is completely eliminated by treatment with (-Ptase.
