CST Technologies, Inc. was founded in 1986 by Dr. Anand Akerkar to provide synthetic substitutes for HSA, BSA, serum, and human urine used in diagnostic reagents. Their synthetic products, including SeraSub, UriSub, and LoSo UriSub, are room temperature stable and can stabilize various enzymes and analytes. These substitutes have been utilized by the in-vitro diagnostic industry for almost 20 years, offering stability and consistency without the need for refrigeration. CST Technologies' synthetic matrixes eliminate the need for lyophilization, ensuring lot-to-lot consistency and stability at room temperature for 2 years. Their products aim to address the challenges posed by human serum-based products and provide an alternative solution for standards and controls in diagnostics.
