The Biosensis ApoE/Aβ Complex ELISA kit is a sandwich ELISA that allows the preferential measurement of ApoE/Aβ complexes. This kit consists of a pre-coated mouse monoclonal anti-Aβ capture antibody, a highly validated ApoE/Aβ complex standard that is pre-formed, lyophilised and ready for reconstitution, a biotinylated ApoE detection antibody, and horseradish peroxidase (HRP)-conjugated streptavidin and detection reagent. The addition of a substrate (3,3’,5,5’-tetramethylbenzidine, TMB) yields a coloured reaction product which is directly proportional to the level of ApoE/Aβ complex present in samples and protein standards. Importantly, a well-characteriaed and unique ApoE/Aβ complex is included as a standard. This complex is pre-formed and lyophilised, requiring only reconstitution with assay diluent prior to use.

Aviva Systems Biology RHOT1 ELISA Kit (Human) (OKEH03665) is based on standard sandwich enzyme-linked immuno-sorbent assay technology. An antibody specific for RHOT1 has been pre-coated onto a 96-well plate (12×8 Well Strips) and blocked. Standards or test samples are added to the wells and removed. A biotinylated detector antibody specific for RHOT1 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 RHOT1 captured in well.

The Biosensis Mouse and Rat proNGF Rapid enzyme-linked immunosorbent assay (ELISA) Kit is a sandwich ELISA that allows the quantification of rodent full-length proNGF protein in less than 4 hours in cell culture supernatants, cell lysates and tissue homogenates only if used as directed. This ELISA Kit has also successfully been used on mouse urine samples (Ryu JC et al., 2018). Please refer to the kit protocol for specific use instructions for each substrate application.

This ELISA kit contains a recombinant mouse proNGF standard expressed in E.coli and consists of a pre-coated anti-proNGF capture antibody, a biotinylated anti-proNGF detection antibody and horseradish peroxidase (HRP)-conjugated streptavidin. The addition of a substrate (3,3',5,5'-tetramethylbenzidine, TMB) yields a colored reaction product which is directly proportional to the concentration of proNGF present in samples and protein standards. A proNGF positive control (QC sample) is provided to assure consistent assay performance. This ELISA kit detects rat proNGF due to high degree of homology (96%) with mouse proNGF based on amino acid sequence, and the ability of this kit in detecting proNGF in rat PC12 cell lysates and rat brain tissue homogenate. In the absence of a true rat proNGF standard, results may be expressed as 'mouse proNGF equivalents'. This ELISA kit shows only 20% reactivity with the human form of proNGF and is therefore not suitable to quantify human proNGF. No cross-reactivity was observed with mature mouse NGF and full-length proBDNF when tested in assay buffer.

The antibodies used in this ELISA kit bind epitopes within the pro-domain (capture) and mature domain (detection) of the protein, thus this ELISA assay does not detect the pro-domain peptide. This kit has not been tested for other applications. Sufficient amount of proNGF standard is supplied to allow for spike- and recovery experiments in order to validate this ELISA assay for other sample matrices if required.

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.
