Growth Properties: adherent, Cells form islands that dome and the monolayer may not become confluent.
Organism: Mus musculus (mouse)
Morphology: epithelial
Source: Organ: testis
Strain: C57BL/6
Disease: Leydig cell tumor
Cell Type: Leydig cell;
Cellular Products: progesterone [22276]
Permits/Forms: In addition to the MTA mentioned above, other ATCC and/or regulatory permits may be required for the transfer of this ATCC material. Anyone purchasing ATCC material is ultimately responsible for obtaining the permits. Please click here for information regarding the specific requirements for shipment to your location.
Applications: transfection host (Roche FuGENE® Transfection Reagents)
Receptors: chorionic gonadotropin; luteinizing hormone (LH) [22276]
Tumorigenic: Yes
Cytogenetic Analysis: polyploid; modal number = 95 [22276]
Gender: male
Comments: This line was established from the M548OP transplantable Leydig cell tumor carried in C57BL/6 mice. [22276]
The cells retain the hormonal responsiveness of the original tumor.
Membrane adenyl cyclase activity is stimulated by treatment with human chorionic gonadotropin (hCG), luteinizing hormone, cholera toxin, sodium fluoride and guanyl-5'-ylimidodiphosphate, and produce progesterone in response to hCG. [22276]
Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Temperature: 37.0°C
Subculturing: Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:6 is recommended
Medium Renewal: Every 3 to 4 days
Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37C) until the cells detach.
Add fresh culture medium, aspirate and dispense into new culture flasks.
Preservation: Culture medium, 95%; DMSO, 5%
Doubling Time: 35 to 40 hrs
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2001
recommended serum:ATCC 30-2020

文献和实验「没爹」小鼠来了!科学家只用 1 个卵细胞培育出健康小鼠,还可正常繁殖后代
mammalian oocytes 的研究论文,通过基因编辑技术,他们探索了靶向表观遗传改造是否可以改善哺乳动物的孤雌生殖。他们的研究结果证明,在对 ICRs 进行基因编辑改造之后,能够直接从单个未受精的小鼠卵母细胞产生可存活的足月后代。 本研究报道的哺乳动物的孤雌生殖,是单性生殖的重要科学进步。 图片来源:PNAS 主要研究内容 研究人员指出,由于基因组印记的存在,先前旨在产生哺乳动物孤雌生殖后代的研究工作均失败了。因此,研究人员首先采用了不同的方法尝试去克服这个问题。 他们从雌性小鼠身上取出
小鼠腹水及单细胞悬液制备流程 配制 6% 淀粉肉汤。 6% 淀粉肉汤配制方法:牛肉膏 0.3g、蛋白胨 1.0g、氯化钠 0.5g、蒸馏水 100mL,上述材料混合加热后加入可溶性淀粉 6.0g;溶解后,121℃ 高压灭菌 15~20 min,EP 管分装封口,将肉汤放置于 4℃ 保存。 小鼠腹腔注射 1mL 6% 淀粉肉汤(注意避开肠管和内脏),刺激 60~72h。 颈椎脱臼法处死小鼠,用 75% 酒精浸泡小鼠 5min。 将小鼠置于解剖板中,固定四肢,剪开皮肤,充分暴露腹膜。 用眼
小鼠外周血单细胞悬液制备 采集小鼠外周血样本于抗凝管中。 离心管内加入 100 μL 新鲜血,加入 1 Test 对应流式抗体,混匀,4℃ 避光孵育 30 min。 加入 2 mL 1×红细胞裂解液,混匀,4℃ 裂解 5 min。 300 g 离心 5 min(裂解完立即离心,防止时间过长损伤细胞),弃上清可得到白色的细胞沉淀。 PBS 洗涤一遍。 加入 200 μL 细胞染色缓冲液重悬细胞,用流式细胞仪进行检测和分析。 注意事项: 采血用抗凝管,有肝素和 EDTA 两种,若直接裂解
