Anti-H-Ras Antibody

This unconjugated rabbit polyclonal antibody targets H-Ras, a 21 kDa small GTPase that links receptor tyrosine kinase activation to the MAPK/ERK cascade. Raised in rabbit and validated for western blot, immunohistochemistry, and immunofluorescence workflows, the reagent from Antibodies.com is supplied as 100 µl of antiserum suitable for probing endogenous H-Ras expression in human cells and tissue sections.

H-Ras is one of three closely related Ras isoforms (H-, N-, and K-Ras) and is mutated in a subset of head and neck, thyroid, and urinary tract cancers, making isoform-resolved detection valuable for oncology research, signal transduction studies, and characterization of patient-derived tumor material. The antibody is reactive with human H-Ras and is unconjugated, allowing researchers to pair it with their preferred HRP, fluorophore, or biotin-labelled secondary reagents.

For best results, store aliquots at -20 °C and avoid repeated freeze-thaw cycles; the 100 µl pack size supports single-use distribution across multiple experimental runs.
