Description générale

ASPP1 interacts with p53 to enhance p53-induced apoptosis.
Monoclonal Anti-ASPP1 (mouse IgG1 isotype) is derived from the hybridoma LXO54.2 produced by the fusion of mouse myeloma cells (SP2/0 cells) and splenocytes from BALB/c mice immunized with a recombinant fragment of human ASPP1, amino acids. Apoptosis-stimulating protein of p53, 1 (ASPP1) belongs to the ASPP family of proteins. This protein contains a proline-rich region, four ankyrin repeats, and an SH3 domain in the C-terminal end.

Immunogène

recombinant fragment of human ASPP1 (amino acids 1-308).

Application

Monoclonal Anti-ASPP1 antibody can be used for western blot at 1-2 μg/mL using total cell extract of human osteogenic sarcoma, U-2-OS. The antibody can also be used for microarray and immunoprecipitation assays.

Actions biochimiques/physiologiques

Apoptosis-stimulating protein of p53, 1 (ASPP1) is known to stimulate RAS signalling which subsequently enhances p53-dependent apoptosis in cancer cells. Furthermore, ASPP1 can also induce p53-independent apoptosis by enhancing the apoptotic functions of p63 and p73. Monoclonal Anti-ASPP1 antibody recognizes human and mouse ASPP1.

Forme physique

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
