Bio-Rad Laboratories last week released a product application guide for the ProteOn XPR36 protein interaction array system. The guide describes four antibody characterization and development protocols for the system. The protocols are hybridoma screening and ranking, epitope mapping, kinetic analysis of antibody-antigen specificity, and determination of cross-reactivity of antibodies used in multiplex assays, the company said in a statement.

Last month AnaSpec introduced a series of peptides and antibodies. The peptides include protease-activated receptor-4; PAR-4 agonist; amide; human and AGA-(C8R) HNG17; and humanin derivative.

The antibodies include anti-MAP1-LC3 beta (NT) and anti-PTEN (pSer385).

The company also introduced the CEF control peptide pool, which had been previously available only individually. The peptide pool is a group of 32 peptides, 8 to 12 amino acids in length. Sequences are derived from the human cytomegalovirus, Epstein-Barr virus, and influenza virus.
