Members of the Bcl-2 protein family function to inhibit (Bcl-2, Bcl-XL, Mcl-1, A1) or promote (Bax, Bak, Bcl-Ls, Bad) apoptosis. Bid is a
Bcl-2 family death agonist that heterodimerizes with either agonists (Bax) or antagonists (Bcl-2). Bid contains a centrally located BH3 domain
that allows interaction with the BH1 domain of Bax and Bcl-2, as well as two caspase cleavage sites (CCS). However, Bid does not contain
other domains commonly found in Bcl-2 family members, such as BH1, BH2, or BH4. In addition, Bid does not contain a C-terminal
hydrophobic region that is characteristic of membrane-bound Bcl-2 family members. Singlet oxygen-induced apoptosis in human leukemia
cells and Fas-induced apoptosis involve caspase-8 cleavage of Bid, which produces a 15 kDa C-terminal fragment and a 6.5 kDa N-terminal
fragment. The C-terminal fragment translocates to the mitochondria and promotes the release of cytochrome C through a mechanism that
might involve destabilization of the mitochondrial membrane. Thus, the proapoptotic role of Bid may involve mitochondrial membrane
destabilization, as well as multiple protein-protein interactions.

注意事项:
1.Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2.Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
