主要成分:甘油、冷冻保护剂、生理盐水等。
产品定位:适用于红细胞。
预期用途:适用于红细胞的低温冷冻保存。
使用说明:冻存液在灌装前已进行灭菌处理,使用前需回温至25℃以上,按红细胞冻存规程操作。
细胞冻存规程:
1、冻存前准备:
(1)制备压积红细胞(200 mL全血制备的压积红细胞体积约为68 mL)。
(2)将红细胞与冻存液分别置于室温1小时,使二者温度达到至少25℃(若红细胞直接从室温全血中分离得到,可省略此步骤)。
(3)冻存液用量计算:
每毫升压积红细胞需冻存液2.35 mL
所需冻存液体积 = 压积红细胞体积×2.35
示例:200 mL全血制备的压积红细胞体积约为 68 mL,所需冻存液体积:68×2.35 =160 mL。
2、冻存步骤:
(1)将需要冻存的压积红细胞转移到无菌容器中,计算需要冻存的细胞体积V1。
(2)根据上述冻存液用量计算,所需要的冻存液体积为2.35 mL×V1(以下简称为V2)。
(3)向红细胞中加入1/4 V2体积的冻存液,轻轻吹打或摇匀(或使用摇床混匀),在室温下保持30 min。
(4)重复步骤(3),每次添加的冻存液体积均为1/4 V2,待完全添加结束,室温保持30 min。
(5)将红细胞悬液转移至冻存袋或冻存管中。
(6)将红细胞放入冻存盒,转移至-80℃冰箱保存(无需转入液氮)。
细胞复苏规程:
1、将冻存红细胞从-80℃冰箱取出。
2、迅速置于37℃水浴中,轻轻晃动,直至完全融化,该过程大约持续10 min,解冻完成。
3、立即进行红细胞洗涤。
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: Glycerol , cryoprotectant, normal saline, etc.
Product Positioning: Suitable for red blood cells.
Intended Use: Suitable for cryopreservation of red blood cells at low temperature.
Instructions for Use: The freezing medium has been sterilized before filling. Warm it up to above 25℃ before use and operate in accordance with the cryopreservation protocol for red blood cells.
Cell Cryopreservation Protocol:
1. Pre-cryopreservation Preparation
(1) Prepare packed red blood cells (The volume of packed red blood cells prepared from 200 mL whole blood is approximately 68 mL).
(2) Place red blood cells and freezing medium at room temperature for 1 hour to bring both to a temperature of at least 25℃. This step may be omitted if red blood cells are isolated directly from whole blood kept at room temperature.
(3) Calculation of required freezing medium volume:
2.35 mL freezing medium is required per milliliter of packed red blood cells.
Volume of required freezing medium = Volume of packed red blood cells×2.35
Example: The packed red blood cells derived from 200 mL whole blood measure about 68 mL, so the required freezing medium volume is calculated as 68×2.35=160 mL.
2. Cryopreservation Procedures
(1) Transfer the packed red blood cells to be cryopreserved into a sterile container and record the cell volume as V₁.
(2) Calculate the required freezing medium volume as V₂= 2.35 mL×V₁.
(3) Add freezing medium equivalent to 1/4 of V₂ to the red blood cells, mix gently by pipetting, shaking or using a shaker, then incubate at room temperature for 30 min.
(4) Repeat step (3), adding 1/4 V₂ freezing medium each time. After all medium is fully added, incubate the mixture at room temperature for another 30 min.
(5) Transfer the red blood cell suspension into cryobags or cryovials.
(6) Place the samples into a cryobox and store in a -80℃ refrigerator (liquid nitrogen transfer is not required).
Cell Thawing Protocol:
1. Take the cryopreserved red blood cells out of the -80℃ refrigerator.
2. Immediately immerse them in a 37℃ water bath and shake gently until completely thawed; this process takes approximately 10 minutes.
3.Perform red blood cell washing right after thawing.
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.
