Antigen/Purification: Collapse
The antigen is a peptide corresponding to amino acid residues from the N-terminal region of human Dynamin, conjugated to keyhole limpet hemocyanin (KLH).
The antibody is prepared from pooled rabbit serum by affinity purification via chromatography on an affinity column made with the N-terminal peptide used as antigen.
Biological Significance: Collapse
Dynamin is a member of a group of nerve terminal proteins called dephosphins that regulate synaptic vesicle endocytosis (Cousin et al., 2001; Graham et al., 2002; Tsuboi et al., 2002). There are 3 known isoforms of Dynamin, each having several splice variants as well. Dynamin I is expressed only in neurons whereas Dynamin II is ubiquitously expressed and Dynamin III is found primarily in the testes. Dynamin 1 is phosphorylated by PKC and dephosphorylated by calcineurin.
Storage
100 µl in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg BSA per ml and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.
For long term storage –20° C is recommended. Stable at –20° C for at least 1 year.
