Measuring the activities of alkaline
phosphatase (Alk) and beta-galactosidase
(Gal) in crude cell extracts. Early and late
passage bone marrow mesenchymal stem
cells are solubilized in a lysis buffer, and
cell lysates are mixed with Alk and Gal
assay solutions. The assays demonstrate
differential changes in enzyme activities
during stem cell senescence in culture.

Measuring ethanol content in Red Beaujolais
Wine using our Ethanol Assay kit. The Ethanol
Assay Solution is mixed with 50 ul of 200-fold
diluted Red Wine, and the mixture is incubated
for 30 min. O.D.492 nm is measured, and
ethanol concentration is deduced from an
ethanol standard plot. The assay shows that the
Red Wine contains ~13% alcohol.

Versatile ethanol assay
Popular L-lactate assay
Measuring L-lactate levels in culture
media. HEK293 cells constitutively
expressing bcl-2 show altered glucose
metabolism. Culture media are diluted 10
fold and mixed with the Lactate Assay
Solution. L-lactate concentrations are
deduced from a lactate standard plot. The
assay reveals that lactate production by
the Bcl-2 expressor is reduced compared
to the parental HEK293 cells.
Rapid purification of plasmid DNA for DNA
sequencing and molecular cloning. Plasmid
DNA is isolated using our simple and
inexpensive Plasmid DNA Purification kit.
Each sequencing run can generate up to ~1kb
sequence information.

Sensitive detection of serum D-lactate
Measuring D-lactate levels in human
serum. Less than 0.05 ml of human
serum is required for the detection. The
sensitive D-lactate assay can detect as
low as 10 uM D-lactate present in serum
in ~30 min.
