Anti-CST8 Antibody

Manufactured by Antibodies.com, this primary antibody is a rabbit polyclonal reagent raised against the human CST8 protein (cystatin 8, also known as CRES and CTES5), generated using recombinant human CST8 protein as the immunogen and affinity-purified to detect endogenous levels of the total CST8 target. It is supplied at a 1.0 mg/mL concentration in a 50 µL volume, prepared in phosphate-buffered saline (without Mg²⁺ and Ca²⁺) at pH 7.4 with 150 mM NaCl, 0.02% sodium azide and 50% glycerol as a cryoprotectant. The unconjugated antibody is recommended for Western blot, immunohistochemistry and immunocytochemistry/immunofluorescence workflows and has been validated on human samples, making it suitable for studies of reproductive biology and spermatogenic cell function where CST8 is normally expressed. As a polyclonal reagent raised in rabbit, it offers broad epitope coverage on the CST8 antigen, and the unconjugated format allows researchers to pair it with their own secondary detection systems, including HRP-, biotin- or fluorophore-conjugated anti-rabbit IgG. For long-term integrity the product should be stored at –20 °C, where the 50% glycerol content provides protection against freeze-thaw damage. The reagent is intended for research use only and is not validated for diagnostic or therapeutic applications. Provided through the Antibodies.com catalogue, the 50 µL size is dispatched from the supplier's facility with a typical lead time of 4–6 business days, with larger 100 µL packings also available for laboratories running higher-throughput screening campaigns.
