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 behavior than what can be handled by traditional chemical analysis and titration.

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.
UOM:  1 * 1 KIT

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
MSDS SDS
Catalog Number: (1B1301-KIT)

Supplier:  VWR Chemicals
Description:   The Protein Precipitation Kit utilises a simple trichloroacetic acid (TCA) based method to precipitate proteins in complex mixtures. Only protein in the sample is pelleted, while interfering salts and surfactants remain in the supernatant. A gentle acetone wash removes TCA and co-precipitants allowing the end-user to recover the protein in a small volume of buffer.
UOM:  1 * 1 KIT
Catalog Number: (GAHK20-1KT)

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:   The EarlyToxâ„¢ Cell Integrity Kit enables the differentiation of live cells from dead cells via fluorescent labeling. This is useful for the rapid quantification of cell viability when used with the SpectraMax® MiniMaxâ„¢ 300 Imaging Cytometer or other fluorescence-based cellular imaging instruments.
Supplier:  Biosensis
Description:   The Biosensis NGF Rapidâ„¢ enzyme-linked immunosorbent assay (ELISA) kit is a sandwich ELISA that allows the quantification of human NGF in less than 3 hours in cell culture supernatants, serum, plasma (citrate) and brain extracts only if used as directed.
Supplier:  Cayman Chemical
Description:   For the quantification of oxytocin in plasma.
Supplier:  Biotium
Description:   Viability PCR With PMA and PMAxxâ„¢ dyes
Supplier:  Biotium
Description:   CF® dye labeled dextrans could be used as a fluorescent fluid-phase markers to study cell permeability, endocytosis, or mechanisms of biomolecular delivery. The dextran is 40,000 MW, and contains a formaldehyde-fixable free-amine group.

Supplier:  Cayman Chemical
Description:   An ELISA for quantifying Citrullinated Histone H3 in biological matrices.
UOM:  1 * 96 Tests
Supplier:  Molecular Devices
Description:   The FLIPR® Calcium 6 and 6-QF Assay Kits provide a fast, simple, and reliable fluorescence based assay for detecting changes in intracellular calcium. The Calcium 6 Assay Kit significantly reduces fluorescence background with a one-step protocol. The Calcium 6-QF Assay Kit provides a quench-free option for sensitive targets or multiplexing applications.
Supplier:  Cayman Chemical
Description:   A competitive assay for the quantification of corticosterone in serum and rodent feces.
Supplier:  Cayman Chemical
Description:   For the measurement of 8-hydroxy-2'-deoxyguanosine and 8-hydroxyguanosine.
Catalog Number: (BSBTEK0726)

Supplier:  BosterBio
Description:   Sandwich high sensitivity ELISA kit for quantitative detection of human CXCL4/PF4.
UOM:  1 * 1 KIT
Catalog Number: (BSBTEK0690)

Supplier:  BosterBio
Description:   Sandwich High Sensitivity ELISA kit for Quantitative Detection of Human CCL28.
UOM:  1 * 1 KIT
