菌种的培养:
1、菌种是指食用菌菌丝体及其生长基质组成的繁殖材料。菌种分为母种(一级种)、原种(二级种)和栽培种(三级种)三级。工业发酵的有用菌种,其筛选步骤包括菌种分离、初筛和复筛。
2、挑选具有某种能力的有用菌种,也称种子制备,是指菌种在一定条件下,经过扩大培养成为具有一定数量和质量的纯 菌种的制备过程。以作接入发酵罐中进一步扩大菌体量及合成产物之用。
3、种子制备包括孢子制备和菌丝体制备 菌种制备。
4、保存在沙土管或冷冻管中的 菌种,用无菌手续挑取少许,接入琼脂斜面培养基上,在25℃(或较高温度)下培养5~7天(或较长时间。所得孢子还需进一步用较大表面积的固体培养基以获得更多孢子(对于霉菌类孢子制备,多数采用大米、小米之类的天然培养基)。
5、将培养成熟的斜面孢子制成悬浮液,接种到扁瓶固体培养基上,于25~28℃培养14天。将成熟的扁瓶孢子于真空中抽干,使水分降至10%以下,并放入 4℃冰箱中备用。一次制得的孢子瓶可在 上延续使用半年左右。
6、如果有些 菌种不产孢子,如赤霉素产生菌或产孢子不多的,则可采用摇瓶液体培养制得菌丝体,作种子罐的种子。种子罐的目的是使接入有限的孢子或菌丝体迅速发芽、生长、繁殖成大量菌体。其中的培养基组分应是易于被菌体利用的碳源(如葡萄糖)和氮源(如玉米浆),及无机盐(如磷酸盐)等。作为发酵罐的种子应生命力旺盛、染色深、菌丝粗壮,无杂菌及异常菌体。接种量一般在10%~20%。

资源名称 Ect1/E6E7说明书

种属: Homo sapiens, human│ectocervix; cervix

类型: epithelial HPV-16 E6/E7 transformed

形态: epithelial

提供形式: frozen

安全等级: 2

模式菌株: 未知

应用领域: These cell lines may provide the basis for valid, reproducible in vitro models for studies on cervicovaginal physiology and infections and for testing pharmacological agents for intravaginal application.<br>

培养基: Keratinocyte-Serum Free medium (GIBCO-BRL 17005-042) with 0.1 ng/ml human recombinant EGF, 0.05 mg/ml bovine pituitary extract, and additional calcium chloride 44.1 mg/L (final concentration 0.4 mM)

传代方法: Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes. Note: The cells should not be allowed to become confluent, subculture at 60 to 90% of confluence. Remove and discard culture medium. Briefly rinse the cell layer with 0.25% (w/v) Trypsin-0.03% (w/v) EDTA solution to remove all traces of serum that contains trypsin inhibitor. Add 2.0 to 3.0 ml of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes). Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal. Neutralize the trypsin by adding 6.0 to 8.0 mL of a 1:1 mixture of Dulbecco's modified Eagle's medium and Ham's F12 medium containing 10% fetal bovine serum. Aspirate cells by gently pipetting.  To remove trypsin-EDTA solution, transfer cell suspension to centrifuge tube and spin at approximately 125 x g for 5 to 10 minutes. Discard supernatant and resuspend cells in fresh serum-free growth medium.  Add appropriate aliquots of cell suspension to new culture vessels. Place culture vessels in incubators at 37°C. Cells will not attach well for 24 hours after subculture. Subcultivation Ratio: 1:4 to 1:6 Medium Renewal: Every 2 to 3 days.<br>Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in Culture of Animal Cells, a manual of Basic Technique by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994

保藏方法:
1. 传代培养保藏法
又有斜面培养、穿刺培养、疱肉培养基培养等(后者作保藏厌氧细菌用),培养后于4-6℃冰箱内保存。
2. 液体石蜡覆盖保藏法
是传代培养的变相方法,能够适当延长保藏时间,它是在斜面培养物和穿刺培养物上面覆盖灭菌的液体石蜡,一方面可防止因培养基水分蒸发而引起菌种死亡,另一方面可阻止氧气进入,以减弱代谢作用。
3. 载体保藏法
是将微生物吸附在适当的载体,如土壤、沙子、硅胶、滤纸上,而后进行干燥的保藏法,例如沙土保藏法和滤纸保藏法应用相当广泛。
4. 寄主保藏法
用于目前尚不能在人工培养基上生长的微生物,如病毒、立克次氏体、螺旋体等,它们必须在生活的动物、昆虫、鸡胚内感染并传代,此法相当于一般微生物的传代培养保藏法。病毒等微生物亦可用其他方法如液氮保藏法与冷冻干燥保藏法进行保藏。
5. 冷冻保藏法
可分低温冰箱(-20-30℃,-50-80℃)、干冰酒精快速冻结(约-70℃)和液氮(-196℃)等保藏法。
6. 冷冻干燥保藏法
先使微生物在极低温度(-70℃左右)下快速冷冻,然后在减压下利用升华现象除去水分(真空干燥)。有些方法如滤纸保藏法、液氮保藏法和冷冻干燥保藏法等均需使用保护剂来制备细胞悬液,以防止因冷冻或水分不断升华对细胞的损害。保护性溶质可通过氢和离子键对水和细胞所产生的亲和力来稳定细胞成分的构型。保护剂有牛乳、血清、糖类、甘油、二甲亚砜等。
