AATF / Che-1 antibody (mAb) (Clone 1B2D8)

Host / Isotype

Rat / IgG2a


Human, Mouse





Cat No : 61789,61790 61789



Tested Applications IF, WB

Applications Validated by Active Motif: WB*: 2 - 4 ug/ml IF: 1:100 - 1:500 dilution For optimal results, primary antibody incubations should be performed at room temperature. The addition of 0.1% Tween 20 to all blocking 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.

Storage Some products may be shipped at room temperature. This will not affect their stability or performance. Avoid repeated freeze/thaw cycles by aliquoting items into single-use fractions for storage at -20°C for up to 2 years. Keep all reagents on ice when not in storage.


AATF/Che-1, or Apoptosis-antagonizing Transcription Factoris 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.
