| Background | Bcl-X, also named as BCL2L1 or BCL2L, belongs to the Bcl-2 family and is encoded by the BCL2L1 gene in human. Alternative splicing of Bcl-X results in at least two isoforms，isoform Bcl-X(L) (also named as Bcl-xL) and isoform Bcl-x(S) (also named as Bcl-xS). Bcl-xL is found in tissues containing long-lived postmitotic cells, such as adult brain, while Bcl-xS is expressed at high levels in cells that undergo a high rate of turnover, such as developing lymphocytes. Bcl-X forms homodimer or heterodimer with other Bcl-2 proteins, like BAK, BAX or Bcl-2, to act as anti- or pro- apoptotic regulators. Bcl-xL appears to regulate cell death by blocking the voltage-dependent anion channel (VDAC) by binding to it and preventing the release of the caspase activator, CYC1, from the mitochondrial membrane, and it also acts as a regulator of G2 checkpoint and progression to cytokinesis during mitosis. In contrast, Bcl-xS is a pro-apoptotic protein that promotes apoptosis. |

保存条件:
-20℃或更低温度保存，至少一年有效。由于蛋白的每次冻融均会引起部分失活，所以首次配制成相应浓度的储存液后(请根据产品简介中Reconstitution一栏的信息配制储存液)，须分装后-20℃或更低温度冻存，以避免反复冻融。
注意事项:
由于有些塑料管壁对某些蛋白有较强的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很难与管壁分离。而载体蛋白(Carrier protein，如0.1% BSA等)的主要作用是预先封闭塑料管壁上的蛋白结合位点，使细胞因子或重组蛋白不会粘附于管壁。所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。
本产品在冻干时添加了海藻糖作为保护剂，此时冻干后本产品看起来仍然像是液体，属于正常现象。在冻干工艺上，海藻糖作为常用的冻干保护剂，可显著阻止蛋白质二级结构的改变，防止冻干过程中的蛋白变性。
本产品仅限于专业人员的科学研究用，不得用于临床诊断或治疗，不得用于食品或药品，不得存放于普通住宅内。
为了您的安全和健康，请穿实验服并戴一次性手套操作。
使用说明：
1. 收到产品后请立即按照说明书推荐的条件保存。除非特别注明，碧云天相关产品均为冻干粉，由于微量的蛋白在冻干过程中沉积在管内，形成很薄或不可见的蛋白层，所以在打开管盖前，我们建议在离心机中约8,000-12,000g离心10-30秒，使附着在管盖或管壁上的蛋白聚集于管底。
2. 请根据实验目的并按照产品简介中Reconstitution一栏中的信息配制储存液。大多数细胞因子或重组蛋白的冻干粉是非常容易溶解的，一般用移液枪的枪头轻吹几下或者轻轻摇晃瓶子，即可使细胞因子或重组蛋白完全溶解。请勿用vortex剧烈振荡，以免蛋白变性而失活。
3. 具体的最佳工作浓度请自行参考相关文献，或者根据实验目的，以及特定细胞和动物，通过实验进行摸索和优化。
