由于本产品需新鲜制备，确认订购后约6个工作日才可以发货。个别情况首次制备出现问题，发货时间会顺延。
本产品可以提供十公斤、百公斤乃至吨级的粗酶液，如有需求请联系碧云天。
Glutamate decarboxylase or glutamic acid decarboxylase (GAD) is an enzyme that catalyzes the decarboxylation of glutamate to GABA and CO2.In mammals, GAD exists in two isoforms encoded by two different genes - GAD1 and GAD2. These isoforms are GAD67 and GAD65 with molecular weights of 67 and 65 kDa, respectively. GAD1 and GAD2 are expressed in the brain where GABA is used as a neurotransmitter, GAD2 is also expressed in the pancreas.At least two more forms, GAD25 and GAD44 (embryonic; EGAD) are described in the developing brain. They are coded by the alternative transcripts of GAD1, I-80 and I-86: GAD25 is coded by both, GAD44 - only by I-80. This product with the indicated enzyme activity was briefly purified from engineered E.coli.
