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。

Prolongation of murine hybridoma cell survival in stationary batch culture by Bcl-xL expression
While the ectopic expression of the anti-apoptoticprotein Bcl-2 has been shown to significantly increaseboth cell viability and antibody production in batchculture, some cell lines are refractory to thesemanipulations. For example, the NS/O and theP3x63Ag8.653 murine myelomas, which express highendogenous levels of the Bcl-2 homologue Bcl-xL, areboth resistant to the anti-apoptotic effect of Bcl-2.This indicates that, in these cells, Bcl-2 and Bcl-xLmay be functionally redundant. In order to define therole which Bcl-xL plays in hybridoma cultures, we usedthe Sp2/0-Ag14 cell line. This murine hybridomaexpresses low levels of Bcl-xL and is highly sensitiveto apoptosis induction by cycloheximide (CHX) and byamino acid depletion. Bcl-xL-transfected Sp2/0-Ag14cells were more resistant than the wild type and theplasmid-containing cells to apoptosis induced by CHXand by glutamine depletion. Moreover, when compared tothe vector-transfected control, Bcl-xL-Sp2/0 cellsexhibited a substantial increase in viability instationary batch culture. Interestingly, Sp2/0-Ag14cells overexpressing Bcl-xL showed a growth behaviourthat was similar to the parent myeloma cell lineP3x63Ag8.653. Our results suggest that Bcl-xLexpression levels are sufficient to account for therelative robustness of some hybridoma cell lines instationary batch cultures.
Productive ascites growth of heterohybridomas between Epstein-Barr virus-transformed human B cells and murine P3X63Ag8.653 myeloma cells.
Heterohybridomas between Epstein-Barr virus-transformed human B cells and murine myeloma P3X63Ag8.653 cells were found to produce sizable quantities of human monoclonal antibodies in nude mouse ascites. Mice injected intraperitoneally with two of such heterohybridomas yielded several milliters of ascites fluid which contained nearly 100-fold higher anti-platelet activities than those in routine culture supernatants.

文献和实验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.
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).
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).
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.
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.

与小鼠骨髓瘤细胞(P3-X63/Ag8)融合,融合的细胞既获得了亲代脾细胞分泌特异性抗体的特性,又具有骨髓瘤细胞大量繁殖的能力,成为一种既能分泌特异性抗体又能长命的杂交瘤细胞。该技术为抗体的分子生物学研究提供了全新的手段。极大地促进了免疫学,遗传学,分子生物学的快速发展。 但传统抗体目前也面临诸多问题,如: 每使用一管新抗体都需要进行滴定测试; 多种同型对照,实验设计繁琐; 需要添加Fc阻断试剂; 抗体不佳,阳性细胞群不明显; 抗体作为细胞生物学和生物化学中最重要的试剂之一,科学界每年在这类
