本公司的细胞培养操作规程，供参考
一、培养基及培养冻存条件准备：
- 准备RPMI-1640培养基，90%；优质胎牛血清，10%。
- 培养条件： 气相：空气，95%；二氧化碳，5%。 温度：37℃，培养箱湿度为70%-80%。
- 冻存液：90%血清，10%DMSO，现用现配。液氮储存。
对于贴壁细胞，传代可参考以下方法：
- 弃去培养上清，用不含钙、镁离子的PBS润洗细胞1-2次。
- 加2ml消化液（0.25%Trypsin-0.53mM EDTA）于培养瓶中，置于37℃培养箱中消化2-3分钟，然后在显微镜下观察细胞消化情况，若细胞大部分变圆并脱落，迅速拿回操作台，轻敲几下培养瓶后加入3ml此细胞的培养基终止消化。
- 轻轻吹打后吸出，移入15ml离心管中，在1200RPM条件下离心5分钟，弃去上清液，加入1mL培养液后吹匀。
- 移入到事先准备好的含有5ml培养基的T-25培养瓶中或含有14ml培养基的T-75培养瓶中培养。
3）细胞冻存：待细胞生长状态良好时，可进行细胞冻存。贴壁细胞冻存时，先要消化处理并进行细胞计数。消化方法按照细胞传代方法的1-3步骤进行，最后的重悬液使用血清。悬浮细胞直接计数后离心，用血清重悬浮，加DMSO至最终浓度为10%。加入DMSO后迅速混匀，按每1ml的数量分配到冻存管中。本公司按每个冻存管细胞数目大于1X106个细胞冻存。
注意事项：
1. 收到冻存管细胞后，若发现干冰已挥发干净、冻存管瓶盖脱落、破损及细胞有污染，请立即与我们联系。
2. 所有动物细胞均视为有潜在的生物危害性，必须在二级生物安全台内操作，并请注意防护，所有废液及接触过此细胞的器皿需要灭菌后方能丢弃。
3. 细胞用途：仅供科研使用。
发货方式：
复苏后发货：我们复苏细胞后发货，货期一周左右，免运费。（气温较好建议复苏后发货）

细胞发货采取专业的运输包装，并选择最快捷的运输方式（顺丰速运或其他空运快递）
ras p21 and GAP inhibit coupling of muscarinic receptors to atrial K+ channels
The signal-transducing G protein G k couples muscarinic receptors to K + (K +[Ach]) channels in atrial cells. Recombinant human ras p21 GAP (GTPase activating protein) at subnanomolar concentrations inhibited GTP-dependent channel opening in isolated atrial cell membranes. This inhibition depended on interaction of GAP with ras p21 in the isolated membranes. In addition, recombinant ras p21 proteins blocked the currents; this effect could be blocked by prior incubation of membranes with specific anti-GAP antibodies. We therefore propose that ras p21 GTP complexed with GAP ( ras p21-GAP) blocks K +[ACh] currents. The channel block could be overcome by GTPγS activation of endogenous G k; this indicates that ras p21-GAP does not interfere with interaction of G k with the K +[ACh] channel directly, but prevents coupling of the muscarinic receptor to endogenous G k.
Tumor acidic microenvironment promotes invasion of renal carcinoma 769-P cell line and analysis of the LncRNA expression profile
Objective To explore the effects of tumor acid microenvironment on the invasion of 769-P cell line and to analyze the LncRNA expression profile.Methods 769-P cells were cultured in pH6.6 cell culture medium for 0 h,0.5 h,1 h,2 h,4 h,and 8 h respectively.The expressions of Snail gene and E-cadherin were examined with fluorescent quantitative PCR.The invasion of 769-P cells was detected with Transwell assay.The LncRNA expression profile was analyzed with LncRNA expression profile chip.Results Compared with the 0 h 769-P cells,the 4 h 769-P cells showed significantly upregulated Snail gene while downregulated E-cadherin(both P0.05);the invasion was remarkably enhanced(P0.05);the expression levels of BC040587,KCNQ1DN and PCAT-43 were upregulated,while the expression levels of CTBP1-AS and MEG3 were downregulated(all P0.05).Conclusions Tumor acidic microenvironment can enhance the invasion of 769-P cells.The mechanism may be related to the abnormal expressions of BC040587,KCNQ1DN,PCAT-43,CTBP1-AS and MEG3.

文献和实验1. Chicken intestinal epithelial cells were obtained from NEWGAINBIO company. Cells were cultured on 37℃, with 5% CO2, in the Ham’s F-12 Nutrient (DMEM/12) that contained the following supplementations: fetal bovine serum (5%), in-sulin (5 µg/mL), transferrin (5 µg/mL), selenium (5 ng/mL), epidermal growth factor (5 ng/mL) and penicillin-streptomycin (100–100 U/mL) for cell culturing (full DMEM/12). Experiments were performed with chicken intestinal epithelial cells and working solutions were prepared with plain DMEM/12 without supplementation. For the investigations, cells were seeded onto 96-well, 24-well or 6-well polystyrene cell culture plates.
2. Primary hVICs (passage 2) were cultured to 50–60% confluence and infected with pGMLV-SV40T-puro lentivirus (NewgainBio, Wuxi, China) at a multiplicity of infection of 80 supplemented with 5 µg/mL polybrene (Sigma-Aldrich, Buchs, Switzerland).
3. Tissue was cultured until cells became visible around the tissue, and when the fusion reached 90% (FIGURE 1A) §ask ¦lled with the prepared culturing medium was sent to the company for further immortalisation. Cell immortalisation was done for cell stability and longer-term use. Immortalised cells were cultured with 10% FBS and 1% PS in the DMEM medium. After the cells multiplied and merged, they were routinely passed and grown ( NEWGAINBIO Inc. Wuxi, Jiangsu, China) (FIGURE 1B-C).
4. Mouse primary cultured renal vascular ECs and VSMCs were obtained from Newgainbio company, which were tested by Factor VIII and α-smooth muscle actin (α-SMA), the marker of ECs and VSMCs. RNeasy Mini Kit was used for RNA extraction, and the above protocols were repeated.
5. Porcine primary colon epithelial cells (Newgainbio company, Wuxi,China) were cultured in Dulbecco's Modified Eagle's Medium (Solarbio, Beijing, China) containing 10 % fetal bovine serum (BioInd, Kiryat shmona, Lsrael) at 37 ◦C and 5 % CO2 humidity.
