● 產品說明
Zeocin?
Reagent is a member of the bleomycin antibiotic family. Resistance is conferred
by the Sh ble gene which encodes a 13,665 dalton protein. In cells expressing
the protein, Zeocin? is prevented from binding and cleaving the cellular DNA.
Zeocin? is effective on most aerobic cells and can be used for selection in
mammalian and insect cell lines, yeast, and bacteria. The amount of Zeocin?
required for selection will vary between 50-2000 μg/ml (typically 300μg /ml)
depending on the cell type.
Zeocin可選擇(ze)Sh
ble基因(yin)(yin)表達的(de)細胞(bao)。與現在使用的(de)其他動物(wu)細胞(bao)標記物(wu)無交叉抗(kang)性(xing)(xing)。因(yin)(yin)此這種抗(kang)生(sheng)素(su)(su)可用來分離(li)對其他篩選劑(如(ru):慶大霉素(su)(su),潮霉素(su)(su))有抗(kang)性(xing)(xing)的(de)克(ke)隆。Zeocin是一種屬于爭光霉素(su)(su)家族的(de)糖(tang)蛋白(bai)抗(kang)生(sheng)素(su)(su),在體內能作用于大多數細菌(jun)(包括E. coli)、真(zhen)菌(如:酵(jiao)母菌)、植物細(xi)胞(bao)、動物細(xi)胞(bao)。
● 液(ye)體Zeocin可(ke)用于細胞培(pei)養。
●
用(yong)于篩(shai)選轉化株的Zeocin濃度根據pH值和鹽濃度改變。pH越(yue)高,鹽濃度越(yue)低,Zeocin活性越(yue)大。
●
普通(tong)大(da)腸桿(gan)菌菌株篩選可在25
μg/ml zeocin濃度的低鹽LB瓊脂培(pei)養基(ji)(yeast
extract 5 g/L, Tryptone 10 g/L, NaCl 5 g/L, Agar 15 g/L,pH 7.5)中進(jin)行(xing),pH調至7.5
。
● 動物細胞篩選:根據(ju)不(bu)同細胞系(xi)從100 到
750 μg/ml。
● 植物細(xi)胞篩選:根據不同的(de)細(xi)胞種類和(he)培(pei)養基從(cong)50 到
250 μg/ml 。
●
酵(jiao)母篩選:取決(jue)于種屬和培(pei)養基,S. cerevisiae Sh ble轉化株在50
μg/ml 濃度的YPD培養基中篩選,pH調(diao)至(zhi)7.0。
● 粉末(mo)型配(pei)制方法:
取1 ml Zeocin溶解液加到Zeocin干粉中,徹底溶解,用0.22
μm 一次性濾器抽濾除菌,即配成1
ml(100mg/ml)的Zeocin溶液,-20℃保存。
