  • Human
  • Mouse
  • Rat
Applications:
  • Immunofluorescence (IF)
  • Immunohistochemistry (IHC)
  • Western Blot (WB)
Storage:
 
For long term storage -80˚C is recommended, but shorter term storage at -20˚C is also acceptable as aliquots may be taken without freeze/thawing due to the presence of 50% glycerol. Stock solutions are stable for a minimum of 1 year at -20˚

Application Note:
Dynamin antibody for phospho-Ser774 dynamin labels the purified protein phosphorylated in vitro by Cdk5 but not PKC (Tan, et al. 2003). The labeling of the dynamin band in Western blots of rat brain was blocked by the phosphopeptide used as antigen but not by the corresponding dephosphopeptide. Sheep anti- Dynamin (Ser774) does not cross react with other purified substrates of CDK5 (e.g. amphiphysin and synapsin). Applications include Immunoblotting (IB), Immunofluorescence (IF), Immunohistochemistry (IHC), Western Blots (WB). Human, mouse and rat have 100% amino acid sequence identity with the antigen used to raise the antibody. When internally tested under ideal conditions the working dilutions were 1:1000 for IB and WB.
Background:
Dynamin is a member of a group of nerve terminal proteins called dephosphins that regulate synaptic vesicle endocytosis. Cyclin dependent protein kinase 5 phosphorylates dynamin at Ser774 and Ser778 that are the phosphorylation sites on dynamin phosphorylated in vivo. Phosphorylation of these sites on dynamin is thought to play a key role in synaptic vesicle trafficking.
