Alan Schwartz, PresidentThe company’s impact on in vitro diagnostic (IVD) manufacturing has been profound. With products that eliminate lot-to-lot variation and cold-chain dependencies, CST offers a rare combination of consistency, reliability, and peace of mind. Its unwavering commitment to quality has earned CST a reputation as a silent standard-bearer for laboratories and manufacturers worldwide.
CST’s journey began in the early 1980s when the diagnostics industry heavily relied on human and bovine serum albumin (HSA and BSA) to produce controls and standards. Though common, these biologics presented serious challenges: unpredictable batch variability, sensitivity to temperature fluctuations, and heightened safety risks amid the AIDS and hepatitis epidemics.
During this turbulent period, CST’s late co-founder, Dr. Anand Akerkar, recognized the urgent need for a safer and more dependable alternative. A Ph.D. chemist with a passion for solving real-world problems, Dr. Akerkar pioneered the development of synthetic matrices designed to replace HSA and BSA. His groundbreaking work culminated in creating CST’s flagship innovations—SERASUB, URISUB, and LOSO-URISUB.

These synthetic solutions did more than eliminate the risks associated with biological materials; they revolutionized diagnostic manufacturing. Offering room-temperature stability and eliminating batch inconsistencies, CST’s matrices became a critical advancement that continues supporting global healthcare infrastructure today.
Products Designed for Precision
CST’s pioneering synthetic matrices—SERASUB, URISUB, and LOSO-URISUB—brought a new level of control to an environment once at the mercy of biological variability.
SERASUB, a synthetic serum substitute, provides a stable, contamination-free platform for spiked reagents. Whether calibrating cholesterol levels or hormone assays, manufacturers can trust SERASUB to deliver accuracy without the guesswork of biological samples.
URISUB replicates the chemical composition of natural urine—without sourcing headaches, biohazard concerns, or regulatory red tape. For more specialized applications, LOSO-URISUB, a low-sodium variant, offers precision where it matters most.
All CST matrices share a key advantage: exceptional room-temperature stability, maintaining the integrity of spiked additives without lyophilization or cold-chain logistics—streamlining production and reducing operational costs.

Trust in diagnostics isn’t declared—it’s demonstrated. The company has quietly become a cornerstone in the diagnostic supply chain, earning long-term loyalty from global manufacturers through products that perform exactly as promised—every time.
“Once companies start using our products, they don’t switch. The stability, consistency, and ease of use speak for themselves,” shares Alan Schwartz, president of CST Technologies.
CST’s synthetic matrices are now embedded in the workflows of some of the world’s most respected diagnostic companies. These enduring relationships are a testament to the trust CST has earned through science. Independent validation continues to reinforce its standing. For instance, Zeus Scientific has demonstrated how CST’s SERASUB product replicates the performance of antibody-negative human serum in ELISA production—delivering comparable optical density, greater temperature resilience, and none of the biological variability.
Dr. Anand Akerkar’s foundational research remains a touchstone, continuing to shape the future of synthetic matrices and immunoassay innovation.
A Rising Wave of Recognition
After decades of setting the standard, CST Technologies is stepping into a well-deserved spotlight.
In today’s climate of scalability, reproducibility, and compliance, a new generation of scientists is rediscovering CST’s value. “Interest is ramping up globally. Companies are putting our products head-to-head with traditional reagents, often finding they perform better,” says Schwartz.
The numbers tell the story: a flawless recall record since the 1980s, GMP-certified protocols, and a shelf life of three years without refrigeration. For diagnostic manufacturers facing tightening standards and logistical challenges, CST isn’t just a safer choice—it’s a strategic advantage.
Synthetic Matrices for More Reliable Diagnostic Controls
Biotechnology executives responsible for sourcing synthetic serum and urine products face decisions that extend far more than price or simple supply availability. These matrices are embedded in standards, controls, reference materials, assay-development programs and diagnostic testing workflows. When matrix materials vary between lots, require complex handling or introduce biological uncertainty, they can delay validation timelines, complicate scale-up and reduce confidence in the broader diagnostic system built around them. Purchasing decisions should therefore begin with the matrix’s role in enabling repeatable measurement rather than with catalog breadth alone.
Traditional dependence on human serum albumin, bovine serum albumin, serum and collected urine introduces challenges that organizations can no longer dismiss as unavoidable operational friction. Biological materials often bring variability, endogenous interference, contamination concerns and demanding storage requirements that increase the burden on quality and regulatory teams. Collected urine presents additional complications involving sourcing, cleaning, processing and batch-to-batch consistency. In environments where standards and controls must support dependable measurement, the matrix itself cannot remain unpredictable. Weak base materials can force repeated qualification work, complicate documentation and create avoidable uncertainty when results need to be reproduced across instruments, laboratories or manufacturing sites.
The strongest procurement strategy begins with consistency. A synthetic matrix should provide assay-development teams with a stable foundation capable of preserving spiked analytes without introducing unnecessary variability between batches. This becomes especially important when diagnostic developers need controls that consistently perform within defined ranges or when new assays must be compared against established standards. Matrix behavior should remain predictable enough to support qualification, method transfer and long-term production planning without generating recurring questions about the underlying material.
Stability is equally important. Refrigeration, freeze-drying and reconstitution requirements add cost, handling complexity and operational risk. Liquid matrices capable of maintaining room-temperature stability reduce pressure on storage systems, shipping logistics and laboratory preparation workflows. This advantage becomes even more valuable for organizations managing global supply chains, distributed manufacturing partners or diagnostic products that move repeatedly through commercial distribution networks. Simplified stability requirements also improve inventory planning because quality teams can focus less on storage constraints and more on consistent assay performance.
The final evaluation criterion is suitability for the intended application. Synthetic serum and urine products should not be assessed merely as replacements for biological materials. They should be judged by how effectively they support real-world applications such as clinical chemistry reagents, immunological standards and controls, drugs-of-abuse testing, HCG assays, low-electrolyte urine controls and medical device validation. Executives should look for evidence that suppliers understand how matrix compatibility, analyte recovery, qualification requirements and manufacturing discipline influence adoption within regulated diagnostic programs.
CST Technologies stands out for organizations seeking a specialized supplier rather than a broad catalog distributor. Its portfolio includes SeraSub, a liquid protein-free serum substitute designed for clinical chemistry and immunological standards and controls. UriSub supports urine controls and reference standards, while LoSo-UriSub is tailored for low-electrolyte urine control applications. The company’s differentiation comes from synthetic, room-temperature-stable matrices containing no biological material, eliminating lot-to-lot variation while supporting manufacturing under good manufacturing practices. For organizations replacing HSA, BSA, serum or collected urine in IVD development and control manufacturing, CST Technologies represents a strong and credible choice.
