  • Product overview

    ALDH Activity Assay Kit (Colorimetric) (ab155893) is a simple, fast and reliable method to quantify the ALDH enzymatic activity. In this assay, acetaldehyde is oxidized by ALDH generating NADH which then reduces a colorless probe to a colored product with strong absorbance at 450 nm. The assay can detect < 0.5 mU of ALDH activity in a variety of samples.


    ALDH assay protocol summary:
    - add samples and standards to wells
    - add reaction mix and incubate for 20-60 min
    - analyze with a microplate reader at 5 min and 20-60 min

  • Notes

    This product is manufactured by BioVision, an Abcam company and was previously called K731 Aldehyde Dehydrogenase Activity Colorimetric Assay Kit. K731-100 is the same size as the 100 test size of ab155893.

    The NAD-dependent Aldehyde Dehydrogenase (ALDH) plays a vital role in cellular detoxification. It oxidizes various aldehydes and generates the corresponding carboxyolic acid. ALDH have been found in every cellular compartment. Based on its structure and function, ALDH comprises 3 major classes in mammals: Class 1 and Class 3 (the tumor form) are located in the cytosol and include both constitutive and induced forms; Class 2 is located in the mitochondria and only exists as the constitutive form. In humans, the ALDH superfamily consists of 19 genes. The mutation of ALDH genes (loss of function) causes human diseases such as Type II hyperprolinemia, pyridoxine-dependent seizure and hyperammonemia. Recent studies show that increased ALDH activity leads to several types of malignancies, serves as a cancer stem cell marker and correlates with poor prognosis.

Detailed protocol was easy followed as per kit manual for measuring the ALDH activity in lung cancer cell lines. The data is consistent with the expression level of ALDH protein in the respective cancer cell lines.

Answer

The ALDH Activity Assay Kit (Colorimetric) (ab155893) has not been tested yet in cancer cell lines such as MDA-MB-231 and MCF-7.
Unfortunately, we do not currently have more information about this product. We will update the on-line datasheet for this product as soon as we receive additional data.

Question

I recently purchased the ALDH Activity Assay Kit (ab155893). The “positive control” is not further defined, but I assume that it consists of aldehyde dehydrogenase enzyme(s). Since there are 19 alcohol dehydrogenases in humans, it would be useful to know which one(s) is /are included in the kit.
Furthermore, I was wondering what the ALDH Substrate Mix contains, since acetaldehyde is included in a separate vial.
Kind regards,

Answer

The contents of the substrate mix is proprietary information and cannot be disclosed.
The positive control is an ALDH isolated from Baker’s yeast.

Question

I was wondering if your ALDH activity kit is compatible with cell lysates prepared using RIPA buffer or other similar lysis buffers? If not, does your Assay Buffer serve as a lysis buffer or does the sample need to be mechanically homogenized? Also, can the lysates made in your Assay Buffer be used in other protein assays, such as Western blot or ELISA?

Asked on Feb 26 2013

Answer

We would recommend using our assay buffer for the lysis, as RIPA may not contain all the components required for the reaction to occur. The samples should be homogenized in ice cold assay buffer for 10 minutes on ice (page 8 of the online protocol). Lysates prepared in the assay buffer can also be used in Western blot and ELISA.
