clinical researchers worldwide

Press Release Body = April 12, 2007; ST. LOUIS - Lee Biosolutions is now providing
Human Salivary Amylase to clinical researchers worldwide. Human salivary amylase,
also called ptyalin, is an enzyme produced by the salivary glands that initiates
carbohydrate digestion in the mouth and continues in the body of the stomach after
food and saliva has been swallowed.

Lee Biosolutions' extensive human donor program allows them to process over 500
liters of human saliva per year for their human salivary amylase production
requirements. Their high purity human salivary amylase enzyme has already been
qualified by major IVD manufacturers worldwide.

According to Lee Biosolutions President Burton Lee, human salivary amylase is one of
a number of new products the company is introducing in 2007.

"We operate with one ear constantly tuned to the research community," Lee said.
"This helps us stay on top of the latest research being conducted, and gives us the
information we need to stay ahead of their demands."

Human Salivary Amylase enzyme is the only enzyme in saliva capable of degrading
oligosaccharides, which are used by the oral microflora for nutritional purposes.
Because human salivary amylase can act anywhere on the substrate, human
alpha-amylase enzyme tends to be faster acting than beta-amylase enzyme.

Human alpha amylase is primarily classified into two kinds of isoenzymes. S-type
amylase comes from salivary glands and P-type amylase from the pancreas. The
company offers both types of isoenzymes in research and bulk quantities, and has the
capabilities to custom purify the human alpha amylase in a wide variety of buffers.

Lee Biosolutions is a leader in the biomarker industry, providing the quality
products to clinical labs and researchers around the world, developing tomorrow's
cures. The company has provided the materials used in a number of high profile
biomarker studies. For more information or to place an order, contact Lee
