Heterobifunctional PEGs

Monodispersed polyethylene gylcol linkers with differing reactive functional ends, such as -OH, -NH2, -SH, hydrazides, carboxylic acids, maleimides, and propynes. Different combinations of reactive functional ends provides adaptive functionality and increased reaction selectivity for bioconjugation, modification, crosslinking, and uses as molecular probes.
