Diluting a lyophilized antibody involves the reconstitution of the dried antibody with an appropriate solvent to achieve the desired concentration for use in experiments. This process typically requires careful consideration of the antibody’s stability, solubility, and intended application. Manufacturers provide guidelines for reconstitution, including recommended solvents and volumes, which should be followed to ensure optimal […]

How Long Are Primers Lyophilized?
Primers, short nucleic acid sequences used in polymerase chain reaction (PCR) and other molecular biology techniques to amplify specific DNA regions, are commonly lyophilized for long-term storage. The duration for which primers are lyophilized can vary depending on several factors, including the stability of the primer sequences, storage conditions, and the manufacturer’s recommendations. Lyophilized primers […]
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 […]
GPO Diagnostics
GPO, or Glycerol-3-Phosphate Oxidase, diagnostics refer to assays or test systems that utilize the enzyme GPO to measure glycerol levels in biological samples. GPO is an enzyme involved in the metabolism of glycerol, catalyzing the oxidation of glycerol to dihydroxyacetone phosphate in the presence of oxygen. This enzymatic reaction produces hydrogen peroxide (H2O2), which can […]
GLDH Calibrators
GLDH (Glutamate Dehydrogenase) calibrators are reference materials used in laboratory assays to calibrate the measurement of GLDH enzyme activity. GLDH is an enzyme found in various tissues, particularly in the liver and kidneys, and it plays a crucial role in amino acid metabolism. Elevated levels of GLDH in the blood can indicate liver or kidney […]
Fructosamine Test Kits
Fructosamine test kits are diagnostic tools used to measure fructosamine levels in blood samples, offering insights into average blood glucose levels over the preceding 2-3 weeks. Fructosamine, formed through the non-enzymatic glycation of serum proteins like albumin in the presence of glucose, serves as an indicator of glycemic control in diabetic individuals. These kits typically […]
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 […]
Disadvantages Of Lyophilization
Lyophilization, while advantageous in many aspects, presents several drawbacks. Firstly, it can be a costly process due to the initial investment in equipment and ongoing maintenance expenses. Additionally, the time required for lyophilization is considerable, with the process spanning several days, making it less suitable for time-sensitive applications. The complexity of controlling factors like freezing […]
Does Lyophilization Kill Bacteria?
Lyophilization is an effective method for preserving biological materials such as proteins, enzymes, exosomes, and vaccines by removing water from the sample while maintaining its structure and function. While lyophilization can reduce microbial activity by removing water essential for microbial growth, it typically does not outright “kill” bacteria. The primary mechanism by which lyophilization inhibits […]
Direct Bilirubin Assays
Direct bilirubin assays are laboratory tests used to measure the concentration of direct bilirubin in blood serum or plasma. Bilirubin is a yellowish pigment produced by the breakdown of heme, a component of hemoglobin from red blood cells. Direct bilirubin specifically refers to the portion of bilirubin that has been conjugated with glucuronic acid in […]
