背景資料

L-Asparaginase is an enzyme that depletes L-Asparagine "an important nutrient for cancer cells" resulting in cancer/tumor cell starvation. L-asparaginase is an anti-tumor agent derived from E.coli.，which can inhibit the growth of malignant cells. It is used mainly for the induction of remission in acute lymphoblastic leukaemia. Because of the lymph node origin of malignant B cells in Multiple Myeloma， L-Asparagine is an essential amino acid for their cell metabolism， and， consequently， L-Asparaginase may be of value in managing the disease.

The rationale behind asparaginase is that it takes advantage of the fact that ALL cellsare unable to synthesize the non-essential amino acidasparaginewhereas normal cells are able to make their own asparagine. These leukemic cells depend on circulating asparagine. Asparaginase however catalyzes the conversion of L-asparagine to aspartic acidand ammonia. This deprives the leukemic cell of circulating asparagine.

溶解建議

提供的L-門冬酰胺酶（L-Asparaginase）產(chǎn)品為過濾滅菌的白色凍干粉末；該凍干粉末是從含L-門冬酰胺酶（L-Asparaginase）的溶液（不含添加劑）中凍干產(chǎn)生的.

保存建議

L-門冬酰胺酶（L-Asparaginase）凍干粉末可以在4℃冷藏保存2周，或置于-20℃凍存，保質(zhì)期2年.
