Lyophilization is a method commonly used to preserve proteins while maintaining their stability and activity for long-term storage. The process typically begins with the preparation of a protein solution, where the protein of interest is dissolved in a suitable buffer solution or solvent. This solution is then rapidly frozen to form ice crystals, usually achieved […]

How are Enzymes Lyophilized?
Enzymes are lyophilized, or freeze-dried, using a process designed to preserve their activity and stability for long-term storage and transportation. In this process, enzymes are typically dissolved in a buffer solution to maintain their native conformation and functionality. The enzyme solution is then frozen rapidly to form ice crystals, usually by immersion in liquid nitrogen […]
Ethylene Glycol Reagents
Ethylene glycol reagents refer to chemical compounds containing ethylene glycol molecules that are utilized in various laboratory processes and industrial applications. Ethylene glycol, a colorless, odorless, and sweet-tasting liquid, is commonly used as a versatile solvent, antifreeze agent, and precursor in the synthesis of polymers, plastics, and other organic compounds. In laboratory settings, ethylene glycol […]
Buffer Lyophilization
Lyophilization of buffers involves the dehydration of buffer solutions to create a dry powder form while maintaining their buffering capacity. This process is crucial for preserving the pH properties of buffers in various biochemical and biotechnological applications. Initially, a buffer solution is prepared by dissolving appropriate buffer components in water to achieve the desired pH […]
Biologic Lyophilization
Biologic lyophilization is a process commonly used in the pharmaceutical and biotech industries to preserve biological substances such as proteins, peptides, antibodies, and vaccines. The process involves freezing the biological material and then subjecting it to reduced pressure, allowing the frozen water to sublimate directly from solid to gas without passing through the liquid phase. […]
Exosome Lyophilization
Exosomes are small extracellular vesicles secreted by cells that play crucial roles in intercellular communication and various physiological processes. Lyophilization is a service/method used to remove water from biological samples while preserving their structure and function. Exosome lyophilization refers to the process of freeze-drying exosomes for long-term preservation and storage. During exosome lyophilization, samples are […]
Custom Lyophilization
Custom lyophilization refers to the process of freeze-drying a substance according to specific customer requirements or preferences. Lyophilization is a dehydration process commonly used in various industries, including diagnostics and biotechnology, to preserve perishable materials or substances. During lyophilization, the substance is first frozen and then subjected to vacuum conditions, causing the frozen water (or […]
Bile Acids Assays
Bile acids assays are laboratory tests designed to measure the concentration of bile acids in biological samples, typically blood or serum. Bile acids are important components of bile, a digestive fluid produced by the liver and stored in the gallbladder. These assays are utilized for various clinical and research purposes. Enzymatic assays utilize enzymatic reactions […]
Basics Of Lyopholized Reagents
Lyophilized reagents, also commonly referred to as freeze-dried reagents, are useful in research, diagnostics, and biotech development. The process of lyophilization, which these reagents undergo, involves freezing the substance and then subjecting it to reduced pressure to remove water via sublimation. This preservation technique ensures the longevity of the reagents and maintains their structural and […]
Ammonium Acetate Lyophilization
Ammonium acetate lyophilization refers to the process of freeze-drying a solution containing ammonium acetate. Lyophilization, also known as freeze-drying, is a method commonly used to remove water from substances while preserving their chemical structure and integrity. Ammonium acetate is a chemical compound composed of ammonium ions (NH4+) and acetate ions (CH3COO-). It is often used […]
