  • Product overview

    SIRT1 Activity Assay Kit (Fluorometric) (ab156065) detects SIRT1 activity in lysates. Primarily, the SIRT1 Activity Assay Kit is designed for the rapid and sensitive evaluation of SIRT1 inhibitors or activators using crude SIRT1 fraction or purified SIRT1. Additionally, any cultured primary cell, cell line, or tissue homogenate can be assayed for SIRT1 activity with the SIRT1 Activity Assay Kit if the appropriate antibody directed against SIRT1 (Anti-SIRT1 antibody (ab7343)) is used for immunoprecipitation.

    Abcam’s SIRT1 Activity Assay Kit (Fluorometric) has been shown to detect the activity of Sirtuins, at least SIRT1 in Human or animal cell lysates or in column fractions. The assay shows good linearity of sample response. The assay may be used to follow the purification of Sirtuins or may be used to detect the presence of Sirtuins in cell lysates.

    Applications for this kit include:

    1. Monitoring the purification of SIRT1.

    2. Screening inhibitors or activators of SIRT1.

    3. Detecting the effects of pharmacological agents on SIRT1.

  • 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.

We use fresh and frozen human serum (n=9).
Blood was collected in purple tubes (with EDTA) and centrifuged for 1500 rpm x 15 minutes for separation.
Part of serum was frozen for 45 minutes, other part kept on ice.
For test we used 30uL of serum. We found no difference in RFU of both samples.
Volumes of reagent are small, it is hard to load in black plate.
It will be nice to have calibration curve for sirt1 activity.
