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.

Fournisseur:  Cayman Chemical
Description:   For the measurement of 8-hydroxy-2'-deoxyguanosine and 8-hydroxyguanosine.
Numéro de catalogue: (BOSSBSKH60390)

Fournisseur:  Bioss
Description:   The microtiter plate provided in this kit has been pre-coated with an antibody specific to EPO. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to EPO. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After the TMB substrate solution is added, only those wells that contain EPO, biotin-conjugated antibody, and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution, and the color change is measured spectrophotometrically at a wavelength of 450 nm ±10 nm. The concentration of EPO in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Fournisseur:  Cayman Chemical
Description:   A 96-well assay for measurement of CREB.
UOM:  1 * 1 KIT
Fournisseur:  Biotium
Description:   MTT, XTT, and resazurin are reduced by mitochondrial metabolic activity to yield coloured or fluorescent products, and thus are useful for and assaying cell viability and quantitating cell number. MTT and XTT are reduced to coloured formazin salts that can be measured by absorbance. MTT generates an insoluble formazin salt, requiring cell lysis before the absorbance can be measured, while XTT does not require cell lysis for measurement. Resazurin is a non-fluorescent blue dye that is reduced to the pink fluorescent compound resorufin, which can be measured by fluorescence or absorbance.
Fournisseur:  ENZO LIFE SCIENCES
Description:   The PROTEOSTAT® PDI assay kit provides a simple, homogenous assay for screening modulators of PDI enzymatic activity. This is accomplished by monitoring PDI-catalyzed reduction of insulin in the presence of Dithiothreitol (DTT), resulting in the formation of insulin aggregates which then bind avidly to the red-emitting fluorogenic PROTEOSTAT® PDI detection dye.

Numéro de catalogue: (ENZOBMLPW05750001)

Fournisseur:  ENZO LIFE SCIENCES
Description:   This kit provides the means to quantify 20S proteasome concentrations in biological samples using a sandwich ELISA technique, utilizing two 20S proteasome specific antibodies for capture and detection purposes together with a highly sensitive substrate. Sample 20S proteasome levels are determined by comparison to a 20S proteasome calibration curve produced in parallel. This kit provides sufficient material for 1x96 well plate set-up to be run.

Numéro de catalogue: (AVIVOKEH03072)

Fournisseur:  Aviva Systems Biology
Description:   Aviva Systems Biology APOC1 ELISA Kit (Mouse) (OKEH03072) is based on standard sandwich enzyme-linked immuno-sorbent assay technology. An antibody specific for Apoc1 has been pre-coated onto a 96-well plate (12 x 8 Well Strips) and blocked. Standards or test samples are added to the wells and removed. A biotinylated detector antibody specific for Apoc1 is added, incubated and followed by washing. Avidin-Peroxidase Conjugate is then added, incubated and unbound conjugate is washed away. An enzymatic reaction is produced through the addition of TMB substrate which is catalyzed by HRP generating a blue color product that changes yellow after adding acidic stop solution. The density of yellow coloration read by absorbance at 450 nm is quantitatively proportional to the amount of sample Apoc1 captured in well.
