Background Information

1.       What is Bcl-2?

Bcl-2 (B-cell lymphoma 2) is an outer mitochondrial membrane protein that via heterodimerization with BAX proteins controls apoptosis. Abnormalities of Bcl-2 activity can lead to cancer, autoimmune diseases, and schizophrenia.

2.       FAQs for Bcl-2

  1.  How to measure Bcl-2 and Bax apoptotic markers by western blotting

    Generally, Bcl-2 protein is considered to have anti-apoptotic activity, while Bax has apoptotic activity. Comparing the ratio between Bcl-2 and Bax protein levels in different samples or cells subjected to treatments can reflect the apoptotic state of the cells. Expression of Bax can vary between cell lines and it is important to compare it to Bcl-2 levels.

  2. What band size should I expect in western blotting for Bcl-2?

    The molecular weight of Bcl-2 is 26 kDa.
