ADS Biosystems Inc. has a very experienced and highly skilled team and provides a wide range of services for academia and industry customers. Our featured services include, but not limited to, antigen-based affinity antibody purification, in vitro kinase assays, Alpha Screen, and custom ELISA kit formation and testing . Our expertise is on human CD34+ hematopoietic stem cells and differentiation into human T cells. We specialize in cell-based assays, such as luciferase assays, in a variety of primary cells, cell lines and tissue cultures. We also provide molecular biology services such as real time RT-PCR, quantitative Western Blot and ELISA, and human cell mutation tests; cell biology services such as stable cell lines with designated reporters, cell differentiation studies with brown and white adipocytes, human adult stem cells, and cochlear organ culture for hearing studies; in vivo mouse model studies for obesity and diabetes. We are capable of testing drug candidates for hearing loss studies in our chemically deafened cochlear cultures, and for obesity and diabetes in vitro with adipocytes and in vivo with mouse models.

Assay development**:
- Custom biochemical and cell-based assay development; routine human and mouse cell-based assays
with custom reporters and endogenous gene expression such as Northern blot analyses, real time RT
PCR and protein level detection with quantitative Western blot assays and ELISA; quantitative assays
for variations in endogenous signal transduction pathways; specialty assay development for human
brown and white adipocyte differentiation in obesity and diabetes, and cochlear organ culture in hearing loss and restoration.
**We are happy to buy commercially available animal models, obesity/diabetes models, cochlea hearing mouse model, tumor models, breast cancer models. We also have access to the following cell lines: cancer cell lines, lung, breast, other routine cell lines like leukemia and lymphoma, fibroblast, mostly human. Our main focus is primary cells, and we can create genetically modified models, mouse fibroblast, etc.
Preclinical drug discovery and development:
- Custom testing of drug candidates for efficacy in human and mouse cell lines, human adult stem cells and cochlear cultures with designated reporters, endogenous gene expression and effects on endogenous signal transduction pathways; in vivo testing of drug candidates in rodents.
Instrumentation:
- Li-cor Odyssey: detects fluorescence, quantifies the signal, very sensitive up to several magnitudes, used to quantify individual bands to compare to loading control
