Description
SMCC-APC is treated with SMCC under conditions that result in only 1~4 moles SMCC on one mole of phycobiliprotein ensuring the best yield of conjugate with minimal formation of aggregates. This derivative protein has been purified to remove excess SMCC and lyophilized, thus quite suitable for long term storage without losing the maleimide reactivity, keep high quality of APC with perfect conjugation consistency
