p40 Antibody Biotin Conjugate / deltaNp63 Rabbit Monoclonal Biotin Antibody [clone TP40/3980R] (V8628BTN)

p40 Antibody Biotin Conjugate. Immunohistochemistry analysis of Tumor protein p40 (deltaNp63) in FFPE human prostate tissue using a p40 Antibody Biotin Conjugate (clone TP40/3980R) demonstrates strong HRP-DAB brown nuclear staining in basal epithelial cells outlining glandular structures, with luminal epithelial cells remaining negative. The nuclear staining is intense and well-defined, forming a continuous basal cell layer pattern that clearly delineates gland architecture. The enhanced signal intensity is consistent with the high affinity of the recombinant rabbit monoclonal format combined with biotin-streptavidin amplification, resulting in robust nuclear detection with minimal background. Surrounding stromal cells remain largely unstained, providing clear contrast and supporting accurate interpretation of deltaNp63-positive basal cell populations. Heat-induced epitope retrieval was performed by boiling tissue sections in pH 9 10mM Tris with 1mM EDTA for 20 minutes followed by cooling prior to antibody incubation.
