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DMEM/F12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。

KLE: A cell line with defective estrogen receptor derived from undifferentiated endometrial cancer
KLE is a cell line derived from a poorly differentiated endometrial carcinoma that is aneuploid with chromosome numbers ranging from 51 to 66 and 6–8 marker chromosomes demonstrated by G banding. Tumors harvested from five of five nude mice bearing an inoculum for more than a month resemble the original specimen, and electron microscopy shows microvilli, many junctional processes, glycogenation, and a prominent nucleolonema. The cell cytosol contains a specific binder for estradiol, but there is no estrogen receptor in the nucleus and in a study reported elsewhere (Raam et al., Breast Cancer Res. Treat. 2, 277 (1982)) translocation to the nucleus fails to occur. The enzyme phenotype of this cell is human, non-HeLa.
Expression of prostatic secretory protein (PSP94) gene in human female reproductive tissues and in endometrial cell line KLE
PSP94, secreted by the human prostate has been implicated as a prognostic indicator of prostate cancer. Prior reports suggest that it is involved in induction of apoptosis and acts as an inhibitor of the growth of prostate cancer cells in vitro and in vivo. PSP94 mRNA expression by female urogenital tissues has not yet been demonstrated. We show the presence of PSP94 transcripts in the human endometrium, myometrium, ovary and in placenta and in the endometrial cell line KLE by RT-PCR, followed by Southern blotting. DNA sequence of the transcripts from KLE cells was identical to the coding sequence of prostate PSP94 cDNA. The expression of PSP94 mRNA and protein were confirmed by in situ hybridization and immunohistochemistry, respectively, in the glandular epithelium of human endometrium. These findings suggest that PSP94 gene is expressed locally in female reproductive system, in addition to the prostate, and indicate a local autocrine paracrine function of PSP94 in the human reproductive system.

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.
Science：直击肿瘤命门，Shibin Zhou 等开发靶向 TP53 突变的双特异性抗体
靶向 TP53 突变和 CD3 的双特异性单链抗体（scDb）。 研究人员首先确证了 p53R175H 在三种人肿瘤细胞系（KMS26, TYK-nu, KLE）中表达，并以 p53R175H/HLA-A*02:01 复合物的形式被呈递到细胞表面。通过噬菌体文库技术筛选得到了两个特异性靶向 p53R175H/HLA-A*02:01 复合物的抗体克隆，分别命名为 H2-scDb 和 H20-scDb。这两个克隆可以特异性地与 p53R175H/HLA-A*02:01 复合物结合，并激活 T 细胞
