本产品是利用细胞内外盐离子浓度差可导致细胞膜胀破的原理来裂解红细胞,主要用于实验中红细胞的去除,比如:淋巴细胞的分离纯化,经酶消化分散的组织细胞的分离纯化,以及组织细胞蛋白与核酸提取等实验中红细胞的去除。

使用说明:
1.向1倍体积的新鲜全血中加入3倍体积的红细胞裂解液(如1 ml新鲜全血加入3 ml红
细胞裂解液)轻轻涡旋或颠倒混匀。
注意:如果对新鲜组织细胞进行处理,需经胰酶等消化成单个细胞悬液,离心收集细胞后再进行后
续操作。
2.冰上孵育15分钟,其间轻轻涡旋混匀两次。
注意:红细胞裂解后,溶液应该是清亮透明的。
3.4℃,450×g离心10分钟收集白细胞,小心吸弃上清液。
4.向以上沉淀中加入两倍体积的红细胞裂解液,轻轻涡旋充分重悬白细胞(如起始血
液为1 ml,则加入2 ml的红细胞裂解液)。
5.4℃,450×g离心10分钟收集白细胞,小心并彻底吸去上清液。
6.重悬细胞,用于后续实验。
注意:如提取RNA,最好从此步开始使用无RNase的溶液进行。
This product uses the principle that the concentration difference of salt ions inside and outside cells can cause cell membrane swelling to lyse red blood cells. It is mainly used for the removal of red blood cells in experiments, such as the separation and purification of lymphocytes, the separation and purification of dispersed tissue cells through enzyme digestion, and the removal of red blood cells in experiments such as tissue cell egg white and nucleic acid extraction.

Instructions for use:
1. Add 3 times the volume of red blood cell lysate to 1 volume of fresh whole blood (such as 1 ml of fresh whole blood and 3 ml of red blood cell lysate), gently vortex or invert and mix well.
Attention: If fresh tissue cells are processed, they need to be digested into a single cell suspension by trypsin or other enzymes, and then centrifuged to collect the cells before proceeding with subsequent operations.
2. Incubate on ice for 15 minutes, gently vortex and mix twice during this time. Note: After red blood cell lysis, the solution should be clear and transparent.
Collect white blood cells by centrifugation at 3.4 ℃ and 450 × g for 10 minutes, and carefully discard the supernatant.
4. Add twice the volume of red blood cell lysate to the above precipitate, gently vortex and resuspend white blood cells (if the initial blood volume is 1 ml, add 2 ml of red blood cell lysate).
Collect white blood cells by centrifugation at 5.4 ℃ and 450 × g for 10 minutes, carefully and thoroughly aspirate the supernatant.
6. Resuspend cells for subsequent experiments. Note: If extracting RNA, it is best to start using a solution without RNase from this step.
