Modified proteins can also be lyophilized and stored for later conjugation to a sulfhydryl-containing molecule. The bonds formed are non-cleavable SMCC is water-insoluble.
Being membrane-impermeable, it cannot be used for in situ crosslinking of cells and tissues [ 15 ]. Chemical modification of antibodies: an introduction of free sulfhydryl groups in proteins.

Conjugation is the process of attaching an antigen to a larger molecule that will ensure that the antigen will activate an immune response that produces antibodies. B Lymphocytes produce antibodies against foreign antigens that they encounter.
However, the antigen must be large enough that the immune system will mount a humoral response — meaning a response involving antibodies secreted by B cells. Thus, in order to produce an antibody to a specific antigen, the researcher must ensure that the antigen is part of a molecular complex that is sufficiently large to activate a humoral response.
Alternatively, simpler, three-step conjugation kits only require the addition of your antibody to a tube containing your desired label. These kits can help avoid common issues associated with covalent conjugation, including eliminating the need for separation steps to ensure retention of your antibody. Our guide to antibody conjugation describes three common conjugation methods to help you decide which technique will enable you to complete your experiment.
