You Searched For: Assays

An assay is an investigative procedure in laboratory medicine, pharmacology, environmental biology, and molecular biology for qualitatively assessing or quantitatively measuring the presence or functional activity of the analyte, or the entity being targeted by the assay. Generally, assays involve biological materials or phenomena which tend to be intrinsically more complex in composition or in behaviour than what can be handled by traditional chemical analysis and titration.

Catalog Number: (M172-1L)
Supplier: VWR Chemicals
Description: The Bradford protein assay is the preferred colorimetric assay for quantifying total protein concentration. Based upon complex formation between basic and aromatic amino acid residues with Coomassie® Brilliant Blue G-250 dye, the Bradford method is easier, faster, and more sensitive than the Lowry method.
UOM: 1 * 1 L

Catalog Number: (1B1558-KIT)
Supplier: VWR Chemicals
Description: Fluorescent DNA Quantitation Kit uses fluorescent bisBenzimide H33258 dye to bind to AT sequences of the minor groove of double-stranded DNA. In the assay, the sample is excited at 360 nm and when the dye binds to dsDNA an emission spectrum at 460 nm is produced.

Supplier: Merck
Description: The Glucose (HK) Assay Kit is for the quantitative, enzymatic determination of glucose in food and other material.
UOM: 1 * 1 items


Supplier: SIGMA-ALDRICH MICROSCOPY
Description: Bicinchoninic acid is used for the determination of protein concentration. It is responsible for the making of intense purple complex with cuprous ion (Cu+) in the presence of alkaline conditions. The amount of Cu+ is in relation with the protein concentration.

Supplier: MOLECULAR DEVICES
Description: Screen and select high value mammalian clones with label-free, in situ detection of IgG secretion with the ClonePix system, and other cell analysers with a green fluorescent channel.

Supplier: Cayman Chemical
Description: Prostaglandin Screening ELISA kit is used for the quantification of total PG levels in tissue culture medium.

Supplier: Cayman Chemical
Description: WST-1 Proliferation Assay Kit provides an easy to use tool for studying the induction and inhibition of cell proliferation in any<i> in vitro</i> model. The assay is based on the reduction of tetrazolium salt WST-1 to soluble formazan by electron transport across the plasma membrane of dividing cells. This kit will also allow investigators to screen drug candidates involved in regulation of cell cycle.

Supplier: Cayman Chemical
Description: Prostaglandin D₂ Express ELISA kit is a competitive assay that can be used for quantification of PGD₂.

Supplier: Cayman Chemical
Description: A competitive assay that can be used for quantification of PGD₂.

Supplier: Biotium
Description: Nitric oxide donors, nitric oxide synthase inhibitors and nitric oxide detection reagents and kits for nitric oxide (NO) studies.

Supplier: Cayman Chemical
Description: 15(S)-HETE ELISA kit is a competitive assay for the measurement of 15(S)-HETE.

Supplier: Biotium
Description: RedDot™1 is a far-red cell membrane-permeable nuclear dye similar to Draq5™. The dye is ideal for specifically staining the nuclei of live cells.
Catalog Number: (TNB-6611-KIT)
Supplier: Tonbo Biosciences
Description: The APO-DIRECT™ reagent kit provides a two color TUNEL (Terminal deoxynucleotide transferase dUTP Nick End Labelling) assay for labeling DNA breaks and total cellular DNA to detect apoptotic cells by flow cytometry. The kit contains the instructions and reagents required for measuring apoptosis in cells including: positive and negative control cells for assessing reagent performance; washing, reaction and rinsing buffers for processing individual steps in the assay; terminal deoxynucleotidyl tranferase enzyme (TdT), fluorescein isothiocyanate (FITC) deoxyuridine triphosphate (FITC-dUTP) for labeling DNA breaks and PI/RNase A solution for counter staining the total DNA.
