Abcam's PicoProbe ALDH Activity Assay Kit (ab155894) is a
robust tool to quantify ALDH (aldehyde dehydrogenase) enzymatic activity. In
this assay, acetaldehyde is oxidized by ALDH to form the NADH which couples
with the PicoProbe to generate a potent fluorescence (Ex/Em = 535/587). The
ALDH fluorometric assay kit is 10 times more sensitive than the ALDH
colorimetric assay and can detect < 0.05 mU ALDH activity (based on our unit
definition) in a variety of samples. This product is manufactured by BioVision, an Abcam company
and was previously called K741 PicoProbe™ Aldehyde Dehydrogenase Activity
Fluorometric Assay Kit. K741-100 is the same size as the 100 test size of
ab155894. 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. Abcam has not and does not intend to apply for the REACH
