About Us

Our mission of AACL is to continueously develop novel diagnostic and therapeutic products for immunological diseases in animals by using advanced technology of allergy and immunology, finally contributing to progress veterinary science. Since AACL was established as RIKEN venture company, we would like to fully utilize technology and knowledge on allergy and immunology for veterinary fields.

Business Areas

・Clinical laboratory testing (allergy test for the dog, and the other animals)

・Development of products and services related to allergic and immunologic diseases in companion animals and livestock.

・Drug development for animals and humans

・Management of Animal Hospital

Current Business

1. Allergy test for the dog

<Antigen-specific IgE quantitative assay>

The quantitative measurement of IgE, patented by AACL and RIKEN (Patent number Japan:5334269 USA:8, 716, 031 Australia:2009247267), is utilized by veterinarians to compare serum IgE concentrations among allergens, resulting in their identification of the most offending allergen in dogs suffred from allergic diseases. By monitoring serum IgE concentration, veterinarians are able to understand a change of causative allergens over different seasons.

<Lymphocyte proliferative response assay>

Proliferated T-helper lymphocytes against food allergens are measured by flow cytometoric technology. Percentages of CD4+CD25+ cells were shown in this assays.

<CCR4/CD4 positive lymphocyte assay>

This is to measure peripheral T-helper lymphocytes positive for CCR4 molecule. The cells are known to increase in peripheral blood in dogs with atopic dermatitis. Flow cytometry is used for this assasy.
