What is the difference between DSS and BS3 crosslinkers?

BS3 is the water-soluble analogue of DSS (i.e., DSS is the membrane-permeable analog of BS3). DSS is water-insoluble and membrane-permeable, so it can be used for both intracellular and cell surface crosslinking. BS3 is water-soluble and membrane-impermeable, so it can be used for cell-surface crosslinking.

What is the protocol for crosslinking IgG to Dynabeads from the Dynabeads Protein G Immunoprecipitation Kit (Cat. No. 10007D) using DSS (disuccinimidyl suberate)?

For crosslinking the antibody to Protein G Dynabeads, please refer to the crosslinking protocol with BS3 (bis(sulfosuccinimidyl)suberate) or Sulpha-DSS, which is an analogue of DSS. The only difference between these two molecules is that DSS is water insoluble and needs to be solubilized in DMSO before use. You can find the protocol at the following link.

What is the difference between a homo- and a hetero- bifunctional cross-linker?

A homobifunctional cross-linker has the same reactive group on both ends, for example two amine-reactive groups. It is used in a one-step conjugation where the two molecules are mixed prior to the addition of the cross-linker. This leads to less efficient cross-linking because polymers can easily be created. A heterobifunctional cross-linker has two different reactive groups, for example an amine-reactive group on one end and a sulhydryl reactive group on the other. These can be used in two-step conjugations by reacting the fIrst end with the molecule containing its reactive group, and then adding the molecule that is reactive towards the other end. This leads to much more efficient cross-linking because polymerization does not occur.
