  • 製品の概要

    Abcam's Histone Acetyltransferase Activity Assay Kit offers a convenient, nonradioactive system for a rapid and sensitive detection of HAT activity in mammalian samples. The kit utilizes active Nuclear Extract (NE) as a positive control and acetyl-CoA as a cofactor. Acetylation of peptide substrate by active HAT releases the free form of CoA which then serves as an essential coenzyme for producing NADH. NADH can easily be detected spectrophotometrically upon reacting with a soluble tetrazolium dye. The detection can be continuous and suitable for kinetic studies. The kit provides a simple, straightforward protocol for a complete assay.

Our samples were not within the linear range for the booklet's recommended protein concentration. A preliminary serial dilution curve should be prepared prior to running the full assay so as to ensure OD values are within the linear range.

You can use a background control sample, also use a nuclear extract.

I have had the chance to inquire to the lab about the use of a purified IP sample. Theywould suggest using the initial sample without any IP for the HAT assay. If the IP is just for concentrating the sample, they recommend use of spin columns, not IP. ...

The lab has confirmed that this kit has not been validated for measuring Tubulin Acetyltransferase activity.  We have no information about whether it would be suitable for this purpose, but the kit was specifically designed for measuring Histone Acetyl...

Thank you very much for your inquiry. 1.) I can confirm that the HAT activity can be expressed as the relative O.D. value per µg or nmol/min/µg sample. Please have a look at the following example calculation: A. Relative OD/ug: One obtains...

DDT should be avoided, as this compound strongly interferes with the reactions in the kit. There are a few things I would like to suggest: - After acid extracting the histones in your current protocol, the sample could be dialysed overnight in 1...

As long as the tissue samples were frozen appropriately, nuclear lysates generated from these tissues can be used for the HAT assay.

The feedback from the lab is that technically BME should be fine but we have not tested this specifically.

Thank you for your enquiry. I have obtained the following information to help answer your questions: 1) Each kit can test 50 samples. i.e. 100/2, minus the wells for background and the Hela nuclear extract used for a standard 2) If you use a...
