Product Description:

BS3 is a cross-linking reagent reacting the amino groups with each other. Since BS3 has at both ends of the molecule N-hydroxysuccinimide active ester to react selectively with the amino group, it can be conjugated a carrier protein to simple hapten or preparation labeled enzyme. BS3 takes a chemical structure having analkyl chain to the linker moiety. Meanwhile, DTSSP and DSP is capable of cleavage of the disulfide-introduced linker site that is easily reduced by the reducing agent. Further, since the active ester group having a sulfonic acid group is introduced to DTSSP and BS3, it may be carried out labeling reaction without using an organic solvent such as DMSO or DMF.
