For optimal results, primary antibody incubations should be performed at room temperature. The addition of 0.1% Tween 20 to all Blotto solutions may also reduce background. Individual optimization may be required.

Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western Blot.


This antibody was raised against peptide comprising amino acids 1-39 of mouse AATF (Apoptosis-antagonizing transcription factor) (NP_062790).


Purified IgG in PBS with 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.

AATF / Che-1 antibody (mAb) tested by Western Blot.
AATF / Che-1 was detected in 20 µg of HeLa cell nuclear extract with AATC / Che-1 antibody at 2 µg / ml.
MW: 80 kDa


AATF/Che-1, or Apoptosis-antagonizing Transcription Factor is a key regulator of apoptosis through its interaction with MAP3K12 (DLK), as well as regulation of gene transcription and cell profileration through interaction with RNA polymerase II. AATF/Che-1 may promote cell proliferation by acting as a competitor of histone deacetylase 1 (HDAC1) interaction with the growth inhibiting protein pRb. AATF / Che-1 binding to pRb may displace HDAC1 from RB1/E2F complexes, leading to activation of E2F target genes and cell cycle progression.
