Leibovitz's L-15 培养基的缓冲系统由磷酸盐和游离碱基氨基酸组成,代替了传统的碳酸氢钠缓冲系统,同时, 用半乳糖和丙酮酸钠代替葡萄糖可以防止酸性代谢副产物的形成,有助于维持培养液 PH 的稳定,适合用于非 cm² 平衡环境的细胞培养。Leibovitz's L-15 培养基适用于猴肾细胞和 HEP-2 的培养、原代(如胚胎和成人组织)细胞分离、多种病毒的培养以及神经元的培养等。
产品特点:
Leibovitz's L-15不含蛋白、脂质或生长因子。因此,L-15 需要补充剂,通常添加 10% 胎牛血清 (FBS)。

操作指南:
1、将胰酶(胰蛋白酶 0.25%,EDTA 0.02%) 及完全培养基提前恢复至室温。
2、弃掉细胞培养基,用 DPBS 洗涤细胞单层。
3、加入适当的体积 (例如,在 75 cm² 的容器中加入 5 mL ) 的胰酶,确保胰酶完全覆盖细胞单层,37°C 孵育 1-3min,用倒置显微镜观察,确保细胞完全脱离培养瓶表面(轻轻拍打培养瓶有助于细胞脱落)。
4、加入 5-10 mL 完整培养基,冲洗培养瓶壁并混匀,将细胞悬液收集到 15 mL 离心管中。
5、1000 rpm 离心 5-10 min,丢弃上清,用 2-5 mL 完全培养基重悬细胞。
6、测定活细胞密度和存活率,根据细胞类型及实验需求按常规程序接种,孵育和传代。
注意事项:
1、室温运输,到货后 2-8℃,避光保存,避免反复冻融,有效期1年。
2、本产品已滤菌,使用前轻轻摇匀。
3、本公司将不为任何不正常使用此产品时所发生的意外负责。
The buffer system of Leibovitz's L-15 Medium consists of phosphate and free basic amino acids, which replaces the traditional sodium bicarbonate buffering system. Meanwhile, galactose and sodium pyruvate are used instead of glucose to prevent the formation of acidic metabolic by-products, helping maintain stable pH of the culture medium. It is suitable for cell culture in a non-CO₂ balanced environment.Leibovitz's L-15 Medium is applicable to the culture of monkey kidney cells and HEP-2 cells, isolation of primary cells (such as embryonic and adult tissue cells), culture of various viruses, and culture of neurons.
Product Features:
Leibovitz's L-15 contains no proteins, lipids or growth factors. Therefore, L-15 requires supplementation, typically with 10% fetal bovine serum (FBS).

Operating Guidelines:
1. Warm trypsin (0.25% trypsin, 0.02% EDTA) and complete medium to room temperature in advance.
2. Discard the spent culture medium and rinse the cell monolayer with DPBS.
3. Add an appropriate volume of trypsin (e.g., 5 mL for a 75 cm² culture vessel) to fully cover the cell monolayer. Incubate at 37 °C for 1-3 minutes. Observe under an inverted microscope until cells are completely detached from the surface of the culture flask. Gently tapping the flask facilitates cell detachment.
4. Add 5-10 mL of complete medium, rinse the inner wall of the culture flask and mix well. Collect the cell suspension into a 15 mL centrifuge tube.
5. Centrifuge at 1000 rpm for 5-10 minutes, discard the supernatant, and resuspend the cell pellet with 2-5 mL of complete medium.
6. Determine viable cell density and cell viability. Perform cell seeding, incubation and subculture following standard procedures according to cell type and experimental requirements.
Precautions:
1. Transport at room temperature. Upon receipt, store at 2-8 °C in the dark and avoid repeated freeze-thaw cycles. The shelf life is 1 year.
2. This product is sterile filtered; gently invert and mix well before use.
3. Our company shall not be liable for any accidents caused by improper use of this product.
