Anti-CPEB1 Antibody

Raised in rabbit and supplied as 100 µl of unconjugated, affinity-purified IgG, this polyclonal antibody targets CPEB1 (Cytoplasmic Polyadenylation Element Binding Protein 1) and is offered by Antibodies.com as a primary antibody for Western blot workflows. CPEB1 is a sequence-specific RNA-binding protein that recognises cytoplasmic polyadenylation elements in target mRNAs and controls poly(A) tail length, regulating the translational activation or silencing of dormant transcripts in oocytes, neurons, and other cell types. The reagent is validated for detection of endogenous CPEB1 across human, mouse, and rat samples, supporting studies of oocyte maturation, early embryogenesis, synaptic plasticity, learning, memory, and reported tumour-suppressor pathways. Because the antibody is unconjugated, it can be paired with user-chosen HRP, fluorophore, or biotin secondary reagents and titrated to match specific membrane, blocking, and detection chemistries. The polyclonal IgG format enables recognition of multiple epitopes on the target protein, which can be helpful when probing samples where CPEB1 expression is low or where post-translational modification patterns may vary.
