Product Name :
SARS-CoV-2 ORF3A polyclonal antibody Background :
Plays a role in viral egress via lysosomal trafficking. Forms homotetrameric ion channels (viroporin localized at endosomes and lysosomes, that may induce deacidification of lysosomes, allowing safe egress of virions via lysosomal trafficking. Also blocks autolysosomes formation by binding and sequestering the host component VPS39 for homotypic fusion and protein sorting (HOPS on late endosomes. This prevents fusion of autophagosomes with lysosomes, disrupting autophagy and facilitating virus egress. Product :
1mg/ml in PBS with 0.02% sodium azide, 50% glycerol, pH7.2 Storage&Stability :

Describe :

Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. This mechanism is useful when non-specific binding is an issue, for example, in Western blotting (WB) and Immunohistochemistry (IHC). By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific; Specific binding will be absent from the western blot or IHC performed with the neutralized antibody.
