Congratulations! CLASS Laboratory wins 2026 Freezer Challenge

The Central Ligand Assay Satellite Services (CLASS) laboratory has won the Overall U-M Large Lab Award Category and the SPH Large Lab Award Category for the 2026 Freezer Challenge.

About the CLASS lab

The Central Ligand Assay Satellite Services (CLASS) laboratory, housed within the University of Michigan’s Department of Epidemiology, offers comprehensive, end-to-end support for clinical research. We streamline the research pipeline by providing custom-designed collection kits with barcoded, uniquely identified components, followed by secure processing and 24/7-monitored ultra-low or liquid nitrogen storage. With capabilities spanning over 40 routine assays—including ELISA, open-channel chemistry, and coagulation analysis—CLASS is a proven leader in data generation. Over the past 20 years, we have successfully managed more than 1 million samples, produced 100,000 kits, and executed 1.25 million assays, ensuring the highest standards of safety and accuracy for your study.

Our Assay Offerings

The technicians at CLASS Lab are proficient with a variety of assay methodologies, and we will do our best to pair you with an assay solution appropriate for your study. We house several different assay platforms here, each with their own benefits. The Alfa Wassermann ACE Axcel offers testing on common analytes of interest, such as lipids, glucose, iron, and electrolytes – this machine is the first option we assess due to its affordability and consistency. When a more diverse assay menu or higher sensitivity is required, we then consider either the Siemens Centaur CP or Roche Cobas e 411. Both machines are excellent, and provide assays of hormones, inflammatory markers, oncomarkers, and more. We also offer measurement of coagulation components and coagulation time using the Stago STart 4.

Analytes that our machines are not capable of measuring are assessed using enzyme-linked immunosorbent assays (ELISAs) or via multiplex. Our technicians have conducted thousands of ELISAs and have the equipment and expertise to provide consistent results – we can recommend many excellent suppliers of a wide variety of ELISA plates and the manpower to complete them. We can also provide Multiplex plates using our Luminex MAGPIX. Multiplex provides a cost- and sample-efficient platform for measuring multiple analytes on a single sample volume at the same time.

Biospecimen Collection Kits

The organized and auditable collection of samples is crucial to effective research: the CLASS Laboratory has developed technologies to produce custom sample collection kits that are both scientifically rigorous and cost effective.

These kits are designed with serialized, bar-coded sample collection vials tied to bar coded collection forms providing easy data entry by laser scanning and both an electronic and physical (paper) audit trail of sample collection and disposition.

Freezer Storage

We offer biospecimen collection kits tailor-made to your research study, with tubes and components marked clearly with barcoded labels and unique sample IDs. Our inventory of kit components includes a variety of tube sizes, cap colors, vacutainers, needles, labels, boxes, and bags allowing for reduced error in collecting and storing precious biospecimens. We’ve created collection kits as simple as a single saliva sample collected with a 5 mL tube, to complex kits of multiple 9x9 boxes for >200 aliquots of 6 different sample types. We also offer processing of collected samples (i.e., spinning down and aliquoting) when it is logistically feasible for your study. Give us your specifications, and we will design the perfect collection kit for your purposes!
