Napsin A Antibody Biotin Conjugate / NAPSA Detection Antibody [clone NAPSA/3308] (V7604BTN)

Napsin A Antibody Biotin Conjugate IHC Staining. Immunohistochemistry analysis of Napsin A (NAPSA) expression in FFPE human lung adenocarcinoma demonstrates distinct cytoplasmic HRP-DAB brown staining in tumor epithelial cells with minimal background in surrounding stromal regions. The biotin-conjugated format of clone NAPSA/3308 enables enhanced signal detection through streptavidin-based amplification, supporting sensitive visualization of Napsin A consistent with its role as a pulmonary epithelial differentiation marker. HIER was performed by boiling tissue sections in pH 9 10mM Tris with 1mM EDTA for 20 minutes followed by cooling prior to staining.

Analysis of HuProt(TM) microarray containing more than 19,000 full-length human proteins using Napsin A antibody (clone NAPSA/3308). These results demonstrate the foremost specificity of the NAPSA/3308 mAb. Z- and S- score: The Z-score represents the strength of a signal that an antibody (in combination with a fluorescently-tagged anti-IgG secondary Ab) produces when binding to a particular protein on the HuProt(TM) array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If the targets on the HuProt(TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-scores. The S-score therefore represents the relative target specificity of an Ab to its intended target.
