Phosphospecific Antibodies

268 products

Phosphoproteins regulate almost all cellular processes, from neuronal signal transduction in learning and memory to cell division in cancer. The ability to determine the phosphorylation state of specific proteins is essential to establish protein function, and phosphospecific antibodies are the perfect tools for this

A phosphospecific antibody doesn’t just indicate that a protein is present, it shows whether the protein is active. What’s more, it can even detect if the protein is phosphorylated at a specific residue. These specialized antibodies require expert design of the antigen and specialized purification techniques.

PhosphoSolutions has decades of experience in the art of phosphospecific antibody production. Our antibodies boast lot-to-lot consistency, high-specificity, and are reliable and reproducible. Check out our product listing to find your perfect (phospho) Antibodies That Work!™
