New Products

Abgent develops 1000+ new products per year. We provide tools for path-breaking research by developing antibodies that detect a comprehensive library of novel and established targets. For established targets we seek to add antibodies that recognize new epitopes, including post-translational modifications such as phosphorylation and methylation. For new targets we consult with leading experts to accelerate development of antibodies that will propel state-of-the-art research in cellular health and disease.

Peptides

SARS Peptides

Individual peptides for SARS-CoV-2 Spike glycoprotein. In order to study the specificity of cellular immune responses against SARS CoV-2 and potential immunity caused by other human Corona Viruses, Abcepta provides Spike peptide individually, as pools and in plate. These peptides can be used for antigen specific T-cell stimulation in T-cell assays or T-cell expansion.

Cell/Tissues/Lysates

Abcepta's portfolio of cell lines, tissues and lysates are drawn from a range of species and immortalized cell lines. All our cell lines and lysates are validated in key applications.

These tissue lysates can be used in applications such as SDS-PAGE and Western blotting. Whole cell lysates can be used as positive controls for applications such as ELISAs, immunoprecipitation (IP) and Western blotting. Obtaining high-quality whole cell lysates can be tedious as well as time consuming. Abcepta offers a comprehensive portfolio of whole cell lysates for research use. Browse our catalog to find the right whole cell lysate for your experiment.
