Press Release Body = April 17, 2007; ST. LOUIS - Lee Biosolutions announces the
availability of Alpha-1 antitrypsin (AAT or A1AT) Antigen to clinical researchers
worldwide at leebio.com. Alpha-1 antitrypsin is a protein produced in the liver
that blocks the destructive effects of certain enzymes.

An alpha-1 antitrypsin concentration test is used as a tool to help diagnose the
cause of early onset emphysema, especially when a person does not present obvious
risk factors, like smoking or exposure to lung irritants such as dust and fumes.
Alpha-1 antitrypsin tests are also implemented in diagnosing the cause of persistent
jaundice and liver dysfunction indicators, primarily in young children.

According to Lee Biosolutions President Burton Lee, the company continues to
introduce new products on a regular basis in order to stay ahead of the demands of
the clinical research community.

"Production of proteins like alpha-1 antitrypsin is the result of a research trend
that suggested researchers were using it at an increasing rate for a variety of
studies, and were demanding sources for pure and consistent product in runs
compatible with their individual needs," Lee said.

If a patient's alpha-1 antitrypsin concentration is below normal, alpha-1
antitrypsin phenotype testing may be ordered. That testing is sometimes followed by
DNA testing to establish which Pi gene alleles are present.

Lee Biosolutions also offers affinity purified polyclonal antibodies of anti-human
alpha-1 antitrypsin including goat anti-human alpha1 antitrypsin and chicken
anti-human alpha-1 antitrypsin.
