L-谷氨酰胺溶液(200 mM),100×
貨號:PB180420
價格:¥80¥¥¥
- 100mL
產(chǎn)品概述
L-谷氨酰胺(L-Glutamine)是細(xì)胞培養(yǎng)中所必需的一種營養(yǎng)元素,它不僅是細(xì)胞的能量來源,還是參與蛋白質(zhì)合成和核酸代謝的重要物質(zhì), L-谷氨酰胺(L-Glutamine)的缺乏會導(dǎo)致細(xì)胞生長不良甚至死亡。L-谷氨酰胺(L-Glutamine)在溶液中不穩(wěn)定,容易自發(fā)降解,因此在一段時間之后或細(xì)胞生長不良時,需要在培養(yǎng)液中補(bǔ)充一定量的L-谷氨酰胺(L-Glutamine),以滿足細(xì)胞生長的需要。

注意事項
1. 本產(chǎn)品經(jīng)0.1 μm過濾除菌;
2. 使用本產(chǎn)品時應(yīng)注意無菌操作,避免污染;
3. 本產(chǎn)品為200 mM濃縮液,請根據(jù)需要稀釋后使用;
4. 不宜長時間放置于室溫環(huán)境或2-8℃長期保存;
5. 2-8℃中解凍后溶液變成乳液狀屬正?,F(xiàn)象,該情況系L-谷氨酰胺受溫度影響導(dǎo)致溶解度降低而析出,將該溶液表面用75%酒精擦拭搖勻后放入37℃培養(yǎng)箱30分鐘-40分鐘可以溶解至澄清透明,最后搖勻使用,使用過程中切忌反復(fù)凍融,用量較少時建議分裝凍存;
6. 本產(chǎn)品僅用于科研或進(jìn)一步研究使用,不用于診斷和治療。
