Description:

WARNING: This product is for research use only, not for human or veterinary use.

SPDB is useful heterobifunctional cross-linker, which is widely used to conjugate a small molecule drug to a targeted carrier (such as antibody, enzyme, protein and polymer). SPDB can be used to make ADC (antobody drug conjugate. Conjugated to antibodies utilizing disulfide linkers: anti-EGFR-SPDB-DM4 has been widely used.
