Anti-CST4 Antibody

This rabbit-derived polyclonal IgG reagent recognizes CST4, the protein product of the CST4 gene, also known as cystatin S. Cystatin S is a secreted cysteine protease inhibitor, making this reagent useful for research into protease regulation and CST4 protein expression.

For western blot (WB), the antibody can be used to examine CST4 signals in prepared cell or tissue lysates. For immunohistochemistry (IHC), it supports localization studies in tissue sections. The product is listed as reactive with human, mouse, and rat samples, enabling comparative expression studies. Its unconjugated format permits pairing with a compatible labeled secondary antibody, including chemiluminescent or fluorescent detection systems.

The supplied volume is 50 µl. Researchers can apply it to studies of salivary-protein biology, tissue characterization, and expression profiling. Rabbit host, polyclonal clonality, and IgG isotype help guide secondary-antibody selection and experimental controls.
