MCDB 是为特定细胞设计的低蛋白和无血清培养的培养基,MCDB 131是 MCDB 培养基的一种,是由Knedler和Ham设计开发出来的,最初用于培养人微血管内皮细胞 (HMVEC)。MCDB 131 培养基除用于内皮细胞外,还可用于其它细胞类型,如肝细胞、平滑肌细胞、心肌细胞等。
产品特点:
MCDB 131 培养基不同于传统培养基之处在于,其含有微量元素、腐胺、腺嘌呤、胸腺嘧啶以及更高浓度的 氨基酸和维生素,在使用时常与 EGF、氢化可的松、谷氨酰胺以及低浓度血清搭配使用,血清的添加浓度须根 据细胞类型而定。

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,禁止冻融,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。
MCDB is a type of medium designed for low-protein and serum-free culture of specific cells. MCDB 131 is one of the MCDB series media, developed by Knedler and Ham. It was originally used for the culture of human microvascular endothelial cells (HMVEC). In addition to endothelial cells, MCDB 131 medium is also applicable to other cell types, such as hepatocytes, smooth muscle cells, cardiomyocytes and more.
Product Features:
Different from traditional culture media, MCDB 131 medium contains trace elements, putrescine, adenine, thymine, as well as higher concentrations of amino acids and vitamins. It is commonly used in combination with EGF, hydrocortisone, L-glutamine and low-concentration serum. The serum supplementation concentration should be determined according to the specific cell type.

Operating Guidelines:
1. Thaw trypsin (0.25% trypsin with 0.02% EDTA) and complete medium to room temperature in advance.
2. Discard the old 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 flask) 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 flask surface; gently tapping the flask helps cell detachment.
4. Add 5–10 mL of complete medium, rinse the inner wall of the 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 survival rate. Perform cell seeding, incubation and subculture following standard protocols 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.
