You want to buy antibodies? At Biomol you will find the right polyclonal or monoclonal antibody for your research. Select conjugated (labeled) primary antibodies (eg. with FITC, biotin) for direct immunodetection of your antigens or primary plus secondary antibodies for indirect antigen detection.
Antibody fragments such as Fab (fragment antigen binding) or F (ab ') 2 are obtained by cleavage of whole immunoglobulin G (IgG) proteins with papain or pepsin respectively. Since the entire Fc portion of the antibody is absent, these proteins are small and penetrate tissue more easily. Another benefit: less background staining in tissues and cells expressing Fc receptors. Fragmented secondary antibodies are also frequently used to block free binding sites, when several species-identical primary antibodies are used.
Isotype controls are especially helpful in immunohistochemistry and flow cytometry to ensure safe evaluation of the results. In this category you will also find IgG beads, as well as purified IgGs for use as controls for IPs and ELISAs.
You can count on that: We guarantee the function of each antibody sold through Biomol within the specifications.
