F(ab')2 fragments of antibodies are generated by pepsin digestion of whole IgG antibodies to remove most of the Fc region while leaving intact some of the hinge region. Used for specific applications, such as to avoid binding of antibodies to live cells with Fc receptors or to Protein A or Protein G.
Fab fragment antibodies are generated by papain digestion of whole IgG antibodies to remove the entire Fc portion, including the hinge region. Block endogenous immunoglobulins on cells, tissues , or other surfaces. Block exposed immunoglobulins in multiple labeling experiments using primary antibodies from the same species. Fab-label primary antibodies in solution without compromising activity.
When purifying molecules, maximizing efficiency is critical to daily work. The Biotage® Selekt is a lean and compact automated flash system with two column channels, allowing you to run two separations in one instrument. Users can easily switch between normal and reverse phase with the system automatically flushing the solvent lines for you!

A clear non-sterile lid for Microplates, ultra-low profile
The 1260 Infinity II Bio-Inert LC is a dedicated solution for analysis of large biomolecules in biological samples, including monoclonal antibody (mAb) and protein analysis. Metal-free components in the sample flow path and the absence of iron and steel in solvent delivery lines ensure the integrity of your biomolecules, minimize unwanted surface interactions, and increase column lifetime.
The NEOGEN® Filter test system utilizes Filter membranes with 2 mL ampouled media to enumerate and detect a wide variety of microorganisms in liquid samples. NEOGEN Filter, white (6550) – 100 mL sterile disposable membrane filtration unit used for testing liquid samples. The membrane is white with dark gridlines, 56 mm in diameter, with a pore size of 0.45 µm. NEOGEN Filter, black (6555) – 100 mL sterile disposable membr…
