Immunoblotting: 0.5 μg/mL for HRPO/ECL detection. Recommended blocking buffer: Casein/Tween 20 based blocking and blot incubationbuffer. Included Potitive Control: Cell lysate from untreated Neuro 2A (See Protocols for moredetails). Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.
Protocol
Positive Control: Cell lysate from untreated Neuro2A cells, brain endothelioma (Mouse)Format: Lyophilized cell lysate from serum starved Neuro 2A cells. Reconstitution: Restore by addition of 200 µl H2O. After complete solubilization add 200µl 2x SDS-PAGE sample buffer, mix and incubate at 90°C for 5 min. Application: The positive control cell lysate is recommended for immunoblot applications. 20 µl of positive control cell lysate correspond to ca. 20. 000 cells. Use 20 µl/lane (mini gel) for HRPO/ECL detection of the target proteins. Please NOTE: The lyophilized cell lysates conatin SDS and are not recommended forapplications with native proteins such as in immunoprecipitation.
Beclin 1 is a ubiquitous coiled-coil protein that plays a central role in autophagy. It interacts with several cofactors (Ambra1, Bif1 , UVRAG) to activate the lipid kinase Vps34, thereby inducing autophagy. In normal conditions, the BH3 domain of Beclin 1 is bound to, and inhibited by, Bcl2 or Bcl-X(L). This interaction can be disrupted by BH3-only proteins to induce autophagy. Nutrient starvation, a potent physiological inducer of autophagy, can stimulate the dissociation of Beclin 1 from its inhibitors, either by activating BH3-only proteins, such as Bad, or by post-translational modifications of Bcl2. Beclin 1 may play a role in anti-viral host defence, and protects against infection by a neurovirulent strain of Sindbis virus. Beclin 1 is also a haploinsufficient tumour suppressor. Genetic studies revealed that Beclin-1 has structural similarity to the yeast autophagy gene, atg6. Beclin-1 is part of a complex with class III PI3 kinase, Vsp34, that is responsible for autophagosome formation.Synonyms: BECN1, Coiled-coil myosin-like BCL2-interacting protein, GT197, Protein GT197
