Specificity

Apoptosis, or programmed cell death, is a well-documented phenomenon in many cellular systems (Cohen, 1991). It plays a key role in tissue and organ development, as well as in adult tissues during cell turnover. Apoptosis can be induced by a variety of internal and external stimuli including growth factor deprivation, cytokine treatment, antigen-receptor engagement, cell-cell interactions, irradiation and glucocorticoid treatment (Cohen & Duke, 1992). Bcl-2 and one of its homologues, Bcl-XL, protect cells from apoptosis (Nunez & Clarke, 1994; Cory, 1995), while other homologues of Bcl-2 such as Bax, Bad and Bak have been shown to enhance apoptosis (Oltvai, 1993; Farrow, 1995; Chittenden, 1995; Kiefer, 1995). Bcl-XL has been shown to block apoptosis which is induced by a variety of stimuli and, under certain conditions, offers greater protection against apoptosis than Bcl-2 (Boise, 1993; Gottschalk, 1994; Gonzalez-Garcia, 1995; Dole, 1995; Shimizu, 1995). In contrast, Bad and Bax inhibit the protective functions of Bcl-XL and Bcl-2, respectively. Although heterodimerization between Bcl-XL, Bad and Bcl-2/Bax was originally thought to be essential for the differential anti-apoptotic activity of Bcl-XL and Bcl-2 (Oltvai, 1993; Yin, 1994); other results suggest that the formation of heterodimers may not be necessary for this death-repressing activity Cheng, 1996; Gottschalk, 1996). This antibody recognizes Human Bcl-XL (Mr 29 kDa) and Bcl-Xs (Mr 21 kDa).
