You Searched For: ELISAs

Enzyme-linked immunosorbent assays identify and calculate substances such as proteins, peptides, antibodies, and hormones. The provided reagents and supplies allow personnel to combine an immobilized antigen with an antibody that is joined to an enzyme. Following with substrate incubation, the produced antigen-antibody interaction and following conjugated enzyme activity can be measured and assessed. The ELISA kits are available for classroom simulations as well as for professional laboratory purposes.

Supplier: Thermo Fisher Scientific
Description: The 1-Step™ Ultra TMB-ELISA contains soluble TMB (3,3´,5,5´-tetramentylbenzidine) that is ideal for sensitive ELISA-based applications. TMB is a chromogenic substrate for horseradish peroxidase. Once oxidised by the enzyme, this substrate yields a blue product that absorbs at 370 nm and 652 nm. Adding sulfuric or phosphoric acid to stop the reaction changes the product to yellow that absorbs at 450 nm and provides greater sensitivity than the blue product. The 1-Step Ultra TMB-ELISA is supplied ready to use with no mixing required.

Supplier: Enzo Life Sciences
Description: The 17β-Estradiol (Serum/Plasma) EIA kit is a colorimetric competitive enzyme immunoassay kit with results in 3 hours.

Catalog Number: (PIER34022)
Supplier: Thermo Fisher Scientific
Description: TMB (3,3´,5,5´ tetramethylbenzidine) is a substrate for horseradish peroxidase (HRP). The 1-Step™ Turbo TMB-ELISA is a complete solution that contains TMB and a stabilised hydrogen peroxide. TMB has an absorption maximum at 285 nm before oxidation. After oxidation, the maxima are 370 and 652 nm. The blue solution can be measured at 652 nm. However, upon addition of the stop solution (ie. acid) a yellow solution results that can be measured at 450 nm and has a higher sensitivity than the measurement of the blue solution.

Catalog Number: (ALEXADI-901-070)
Supplier: Enzo Life Sciences
Description: Highly sensitive ELISA kit enabling detection of LTC4/D4/E4 in 4 hours.
UOM: 1 * 1 KIT


Catalog Number: (ALEXADI-900-015A)
Supplier: Enzo Life Sciences
Description: This Leptin (Rat), EIA kit is a colorimetric immunometric enzyme immunoassay kit with results in 3 hours. For the quantitative determination of rat leptin in culture supernatants, plasma, and serum.
UOM: 1 * 1 KIT


Supplier: G-Biosciences
Description: The femtoELISA™ kits utilise a non animal protein blocker, NAP-BLOCKER™ that minimises cross-reactivity with researcher's antigens and antibodies. For the detection of HRP, an improved, ultra sensitive, non volatile, stable colorimetric substrate based on tetramethyl benzidine (TMB) is supplied. Reagent does not require hydrogen peroxide that can have detrimental effects on many biological factors, which may ultimately affect the assays.
