Anti-BAP31 Antibody

BAP31 (BCAP31) is a polytopic integral membrane chaperone of the endoplasmic reticulum that participates in the export and quality control of nascent membrane proteins and modulates apoptotic signaling at the ER-mitochondria interface. This polyclonal reagent from Antibodies.com was raised in rabbit against human BAP31 and is supplied as an unconjugated 100 µl vial ready for direct labelling or secondary detection in standard immunodetection workflows. The antibody has been validated for western blot, immunohistochemistry, and immunofluorescence on human cells and tissue, where it produces cytoplasmic and perinuclear staining consistent with the protein's known ER localization. Polyclonal preparations recognize multiple epitopes across the target, which can help when the antigen is partially degraded or shows conformational heterogeneity between sample preparations. Aliquot upon arrival and refrigerate to preserve reagent stability through repeated use. Each lot is produced under the Antibodies.com quality system, and the host species, clonality, and reactivity profile are confirmed in the accompanying datasheet so that secondary antibody selection and blocking conditions can be planned with confidence in cell biology, oncology, and neuroscience research focused on ER-associated protein trafficking and stress pathways.
