SNX12 antibodies are typically generated using recombinant proteins or synthetic peptides. Biotin-conjugated variants undergo additional chemical modification to attach biotin molecules, enabling downstream detection with streptavidin-linked enzymes (e.g., HRP) or fluorophores.
For example, Novus Biologicals’ NBP2-74263B (mouse monoclonal) and LSBio’s LS-C470311 (rabbit polyclonal) are validated for specificity and cross-reactivity in human, mouse, and rat samples .
Biotin-conjugated SNX12 antibodies are employed in diverse assays, with optimized dilutions for sensitivity and specificity.
SNX12 is homologous to SNX3 and interacts with 3-phosphoinositides (PtdIns3P) to localize to early endosomes. Overexpression disrupts multivesicular body (MVB) maturation, impairing lysosomal degradation . Key insights include:
Membrane Binding: Dependent on PX domain interaction with PtdIns3P; mutation of Arg71 abolishes binding .
Retromer Interaction: Co-localizes with retromer components (Vps35, Vps26), suggesting a role in retrograde transport .
High biotin levels in samples (e.g., egg yolk) can cross-react with streptavidin, causing false positives. This is mitigated by optimizing blocking buffers or using non-biotin-based detection systems .
