Signal Transduction and Drug Discovery Services
BioAssay Systems has developed a range of high-throughput assays for drug targets. Our lead discovery services include, but are not limited to, hit-to-lead profiling and structure-activity relationship (SAR) studies.
Signal Transduction and Drug Discovery
BioAssay Systems’ signal transduction and drug screening services are for evaluating changes in cell signaling as a result of exposure to test compounds. The services allow the screening of phosphorylation status modulators in important cell signalling pathways. Our examples include but not limited to the following:
We routinely determine the test compound’s reactivity with different cell species, phosphorylation kinetics and the IC50 of activation or inhibition of the cellular pathway. Learn more.

Customer Testimonials
"The guys at BioAssay Systems know their science! I had to develop a bioassay for our company and Robert was very quick to respond to keep us up to date. They are knowledgeable and very resourceful. They directed us to one of the bulk suppliers that could give us a really good deal on our active ingredient. They keep very detailed records for our research needs. I would recommend working with BioAssay Systems on your assay development projects!"
"It is a pleasure working together with BioAssay Systems. I brought samples to their Hayward location and received the results in less than 24 hr. The discussion with Robert Z was courteous, open, and with a depth of knowledge. Robert has a PhD from Stanford. Also, Frank Huang, the CEO, had sufficient scientific curiosity to try out our cleanser and provide feedback! This is beyond the call of customer relations. BioAssay Systems is a company with a lot of expertise and a friendly, responsive approach to problem solving. I will enthusiastically continue to work with them to carry out our research."
"I would like to show my appreciation to the Bioassay Systems service team. We are developing an assay to measure the change in lactate concentration of single cell samples using fluorescent microscopy. The BioAssay Systems team was quite helpful in assisting us to optimize their fluorescent L-Lactate assay kit for our unique experimental set-up. The BioAssay Systems team is always friendly and knowledgeable. We know that we can rely on them for fast and professional service."
"While developing biodegradable coatings for Drug Eluting Stents I worked with Bob to develop an accurate, precise and sensitive assay for determining the amount of polymer remaining in tissue. It was a pleasure to work with Bob and his team, they are very thorough, they understand the science very well and they always deliver on time and at the right price. I would highly recommend anyone using BioAssay Systems services in the future."
