主要成分:氨基酸、无机盐、白蛋白、冷冻保护剂。
产品定位:适用于原代细胞以及各类肿瘤细胞,保障细胞复苏后的功能与增殖速率。
预期用途:适用于各类细胞冷冻保存,冻存后的细胞仅能用于科研实验或体外分析检测,不能用于临床治疗。
使用说明:本品在灌装前已进行灭菌处理,无需稀释即可使用;细胞培养应按照相应规程进行。
细胞冻存规程:
1.收集对数增长期细胞,离心(1000 rpm,5 min)后去上清。
2.加入完全培养基重悬后进行细胞计数以及活率检测,离心后去上清(如不需要计数看细胞初始状态,此步骤可省略)。
3.使用本产品重悬 (轻柔吹打,避免气泡),推荐冻存密度为 1×10⁶-1×10⁷个 /mL,冻存体积 0.5–1.5mL / 管。
4.将分装好的细胞冻存管,在 4℃孵育 20 min 后转入- 80℃冰箱过夜,次日投入液氮保存即可。
注意:
[1]本公司产品在使用前应提前在 4℃冰箱预冷,避免保护剂因温度过高对细胞造成损伤。
[2]为避免复苏过程中冻存管炸裂,投入液氮之前确保冻存管完全密封。
细胞复苏规程:
1.将含有细胞的冻存管从液氮中取出,迅速置于37℃水浴锅中快速融化。
2.将解冻的细胞转入加有等体积完全培养基的无菌离心管后,离心(1000 rpm,5 min)弃上清液,使用完全培养基重悬细胞。
3.将上述细胞悬液转入加有完全培养基的细胞培养瓶中,混匀后置于细胞培养箱中培养。
注意:复苏后立即检测可能不够准确,贴壁后或4-48h(根据细胞生长特性而定)再进行检测更为准确。
注意事项:
1.收到产品后请立即转移到4℃冰箱中保存。
2.产品使用过程中如接触皮肤或眼睛请立即用水冲洗,若有不适请及时就医。
3.如本产品放置后出现浑浊、沉淀等变质问题,请勿使用并立即联系技术人员。
4.为避免造成细胞污染,请在生物安全柜中开启瓶盖。
This series of Cell Cryopreservation Medium is developed in layers to meet diverse research demands, covering three product models: C1525335, C1525336 and C1525338. It covers three application scenarios including cost-effective routine cell culture, high-standard serum-free protein-based cryopreservation and dedicated low-temperature storage for red blood cells, compatible with most mainstream in vitro experimental samples in laboratories.

Main Components: Amino acids, inorganic salts, albumin, cryoprotectants.
Product Positioning: Suitable for primary cells and various tumor cells, capable of retaining cell functions and proliferation rate of tumor cells after resuscitation.
Intended Use: For cryopreservation of various cells. Cryopreserved cells are only for scientific research or in vitro analytical testing, and cannot be used for clinical treatment.
Instructions for Use: This product is sterilized before filling and can be used without dilution; cell culture shall be carried out in accordance with corresponding operating procedures.
Cell Cryopreservation Protocol:
1.Harvest cells in logarithmic growth phase, centrifuge at 1000 rpm for 5 min and discard the supernatant.
2.Resuspend cells with complete medium for cell counting and viability detection, then centrifuge and remove the supernatant (This step can be omitted if cell counting and initial cell status observation are unnecessary).
3.Resuspend cells with this product (pipette gently to avoid air bubbles). The recommended cryopreservation density is 1×10⁶-1×10⁷ cells/mL, with 0.5–1.5 mL medium per cryovial.
4.Incubate dispensed cryovials at 4 ℃ for 20 min, then transfer to -80 ℃ refrigerator for overnight storage, and move into liquid nitrogen for preservation the next day.
Notes:
[1] Pre-cool the product in a 4 ℃ refrigerator before use to prevent cell damage caused by high temperature of cryoprotectants.
[2] Make sure cryovials are completely sealed before placing into liquid nitrogen to avoid tube rupture during resuscitation.
Cell Thawing Protocol:
1.Take the cryovial with cells out of liquid nitrogen and rapidly thaw in a 37 ℃ water bath.
2.Transfer thawed cell suspension into a sterile centrifuge tube with equal volume of complete medium, centrifuge at 1000 rpm for 5 min and discard supernatant, then resuspend cells with complete medium.
3.Transfer the above cell suspension into a cell culture flask filled with complete medium, mix evenly and culture in cell incubator.
Notes: Test results detected immediately after resuscitation may be inaccurate; detection after cell attachment or 4–48 h (adjust according to cell growth characteristics) will be more accurate.
General Precautions:
1.Transfer the product to a 4 ℃ refrigerator immediately after receiving.
2.In case of skin or eye contact during use, rinse with plenty of clean water at once, and seek medical treatment if discomfort occurs.
3.Do not use the product if turbidity, precipitation or other deterioration appears, and contact technical personnel immediately.
4.Open the bottle cap inside a biosafety cabinet to avoid cell contamination.
