tissues is available at LeeBio.com

Press Release Body = ST. LOUIS - Lee Biosolutions announces the availability of
Human Hemoglobin to clinical researchers worldwide at leebio.com. Hemoglobin is the
molecule in red blood cells that carries oxygen. It combines with oxygen in the
lungs and is responsible for releasing it into the tissues. Human Hemoglobin is
also responsible for the red pigment in blood.

Hemoglobin makes up roughly 97% of the dry content in red blood cells and about 35%
of a red blood cell's total content. A molecule of human hemoglobin consists of 2
pairs of peptide chains (alpha and beta globins) and four heme groups, each with one
atom of iron.

According to Lee Biosolutions President Burton Lee, Human Hemoglobin is the latest
in a long line of products the company has introduced recently to meet the demands
of clinical research professionals.

"We know we're not the only biomaterials provider out there," Lee said. "So we've
made a real effort to set ourselves apart as a premium provider by focusing on the 3
most important areas in our industry- purity, consistency and service."

Mutations in the genes for the human hemoglobin protein are the cause of a group of
hereditary diseases called the hemoglobinopathies. The most common of these
diseases are sickle-cell disease and thalassemia. The hemoglobinopathy of
sickle-cell disease was the first disease to be understood in its mechanism of
dysfunction, completely down to the molecular level.

Hemoglobin levels are among the most routinely ordered blood tests, typically as
part of a complete blood count. The amount of oxygen in the body tissues depends on
how much hemoglobin is in the red cells. If there's too little, the tissues lack
oxygen and the heart and lungs must work harder to try to compensate. Low
hemoglobin levels are usually indicative of anemia. High levels may be caused by
polycythemia vera, a disease in which too many red blood cells are made.

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
