Product News: New PBS-Only Antibodies Enable More Flexible Research

09 Oct 2018


Abcam’s new phosphate buffered saline (PBS)-only recombinant antibodies are free from preservatives and stabilising agents, offering improved flexibility for researchers conducting more complex experiments.

Typically, antibodies are stored in a buffer composed of bovine serum albumin (BSA), glycerol and sodium azide to ensure stability. However, these components can inhibit effective conjugation to certain dyes and enzymes or they can be toxic to live cells. In a concentrated solution, without BSA, glycerol or azide, PBS-only antibodies are ideally suited to antibody labelling, functional and cell-based assays and live cell imaging applications.

Developed using Abcam’s rabbit monoclonal recombinant technology, the PBS-only antibodies are highly reproducible ensuring batch-to-batch consistency and are extensively validated across a wide range of applications including Flow, WB, ChIP, ICC, IHC and Knockout validation. Abcam is now making over 2300 of these antibodies available, via its catalog for global researchers.
