YenZym Antibodies - Custom Antibody Service

P-site™ antibody service (Phosphorylation Site-Specific Antibody)

Post-translational modifications (PTM) play important roles in regulating the biological activity of a protein. Phosphorylatioin is one of the most common PTM carried out by the protein kinases. A properly designed P-site™-specific antibody allows one to monitor the kinase activation event without the use of radioisotope 32p.

Our team of scientists have derived a wealth of experience over the years by making hundreds of P-site™-specific antibodies. The design of the P-site™ epitope critically determines the outcome (yield, specificity and affinity) of the final antibody. Based on your individual project needs, our team will tailor the epitope design accordingly.

Call us also about other PTM-specific antibody services (e.g., hydroxylation, methylation, acetylation, neopeptide, etc.)
