Press Release Body = Lee Biosolutions has announced the production and availability
of five Human Lactate Dehydrogenase Isoenzymes - LDH-1, LDH-2, LDH-3, LDH-4 and
LDH-5 - for purchase at LeeBio.com. Refer to Item No. 355-15 for the most popular
LDH Isoenzyme product from the human heart, LDH-1.

Human lactate dehydrogenase isoenzymes are primarily used by cells in specific
tissue. LDH, also known as lactic dehydrogenase, is responsible for converting
muscle lactic acid into pyruvic acid, an essential step in producing cellular
energy.

When injury occurs, cells containing specific LDH isoenzymes are released in the
bloodstream. Analyzing specific LDH isoenzyme ratios helps identify certain
patterns in order to aid in the diagnosis of disease such as heart attack, lung
injury, lung disease, liver or muscle disease, advanced cancers and autoimmune
diseases.

According to Lee Biosolutions President Burton Lee, the company keeps close tabs on
the clinical research community in an effort to stay ahead of widespread demands for
products like Human Lactate Dehydrogenase Isoenzymes.

"Lee Biosolutions has developed a reputation for high-quality biomarker production,"
said Lee. "We isolate LDH isoenzymes from the human heart, human red blood cells
and the human liver. As a manufacturer of high purity human enzymes, we are able to
custom fill orders and we will, likewise, place the protein in the buffer of your
choice, if required."

Burton also indicated Lee Biosolutions focuses on providing consistently pure
products to the clinical research community. "We continue to expand our product
line based on developing trends in the industry," he added.

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