Clinical Chemistry Reagents
Sigma Aldrich Fine Chemicals Biosciences ProClin 300, 2 L
ProClin biocides are immediately microstatic upon contact with microbial organisms as a result of their ability to quickly penetrate cell membranes and inhibit specific enzymes crucial to cellular respiration. Multiple specific sites of ProClin toxicity prevent microorganisms from developing high levels of resistance, making ProClin highly efficient even over extended storage periods of your IVD components.
Cell Biolabs Inc Lipid Doplet Isolation Kit, 50 preps
Lipid droplets are organelles that are rich in lipids, contain a lipid rich core, and are surrounded by a phospholipid monolayer and associated proteins. They are found in adipose tissue of animals and regulate the hydrolysis and storage of neutral lipids; they also serve as storage for cholesterol and acyl-glycerols used to form cell membranes. More recently they have been associated with inflammatory responses, obesity, atherosclerosis, and cancer. Cell Biolabs’ Lipid Droplet Isolation Kit isolates lipid droplets by simple gradient centrifugation, eliminating the need for ultracentrifugation. A lipid droplet source such as tissue or cultured cells is homogenized. A gradient is then created with the homogenate, and the material is centrifuged. The lipid droplets float to the top of the gradient and are recovered by carefully pipetting from the top of the gradient. Each kit provides sufficient reagents to isolate up to 50 preps based on a 50-100 mg tissue or cell sample size.
Roche Diagnostics Calcium Bio, 200 tests
Calcium is a mineral nutrient, which is reqired in cell cultures and microbial fermentation for optimal growth and product formation. For control of culture media and for monitoring in a culture process, the calcium concentration can be determined on a Cedex Bio or Cedex Bio HT Analyzer with high reliability and convenience.
Roche Diagnostics Pyruvate Bio, 200 tests
Pyruvate is an important source of carbon and energy in cell cultures. It is generated as an intermediate in the glycolysis pathway by the cells using glucose. Control of the pyruvate concentration in the culture by additional feeding of pyruvate enables optimization of cell growth and product formation. For control of culture media and for monitoring in a culture process, the pyruvate concentration can be determined on a Cedex Bio or Cedex Bio HT Analyzer with high reliability and convenience.

D-/L-Lactic Acid Assay Kit, 100 assays, Enzymatic, Spectrophotometric, Absorbance at 340 nm, 0.5 to 30 μg D- or L-lactic acid range
Cell Biolabs Inc Lactate Assay Kit (Colorimetric), 100 assays
Lactic Acid is an alpha hydroxyl acid that can ionize a carboxyl proton to yield the lactate ion, the latter of which exists as two optical isomers L-Lactate and D-Lactate. In the brain lactate, like glucose, is thought to be one of the main sources of energy. High levels of lactate have been found in the extracellular fluid surrounding neurons due to the high metabolic activity of glial cells. Cell Biolabs’ Lactate Assay Kit (Colorimetric) is a simple assay that measures the amount of total lactate present in biological samples in a 96-well microtiter plate format. Sample lactate concentrations are determined by comparison with a known lactate standard. The kit has a detection sensitivity limit of 1.5 uM L-Lactate. Each kit provides sufficient reagents to perform up to 100 assays, including blanks, lactate standards and unknown samples.
