  • Product overview

    Abcam’s SIRT3 Activity Assay Kit (Fluorometric) (ab156067) detects SIRT3 activity in lysates.


    Primarily, the SIRT3 Activity Assay Kit (Fluorometric) is designed for the rapid and sensitive evaluation of SIRT3 inhibitors or activators using crude SIRT3 fraction or purified SIRT3.


    Applications for this kit include:


    1. Screening inhibitors or activators of SIRT3.


    2. Detecting the effects of pharmacological agents on SIRT3.


    SIRT3 assay protocol summary:
    - add assay buffer, substrate peptide and NAD to wells
    - add developer to wells
    - add enzyme sample or recombinant SIRT3 to wells
    - analyze with microplate reader for 30-60 min every 1-2 min

  • Notes

    Histone Deacetylases (HDACs) are a class of enzymes responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4), allowing the histones to wrap the DNA more tightly.

    HDAC proteins occur in four groups (class I, class IIA, class IIB, class III, class IV) based on function and DNA sequence similarity.
    Classes I, IIA and IIB are considered "classical" HDACs whose activities are inhibited by trichostatin A (TSA), whereas class III is a family of NAD+-dependent proteins (sirtuins) not affected by TSA. Class IV is considered an atypical class on its own, based solely on DNA sequence similarity to the others.

Sirt3 activity in liver of Wistar rart

Good Good 4/5 (Ease of Use)
Abreviews
While Sirt 3 activity was easy to measure with the recombinant enzyme, RFU levels from crude liver lysate of Wistar rats were very low. Finally, after several settings (buffer, fractionation, washing steps, etc...), sirt 3 activity was detected in liver of Wistar rats, under our specific experimental conditions.
