ELISA Rat - HO-1

ELISA is the most commonly used method of detecting and quantifying the concentration of an antigen in an unknown sample. During the experiment, If you get a weak signal, then make sure reagents are at room temperature before starting the assay. Try increasing incubation times to ensure maximal antibody binding and amplify the signal. Secondly, if you get values above 0 in the negative control indicates a high background signal. Try to consider reducing your antibody concentration and prevent non-specific binding of antibodies by using affinity-purified antibody and suitable blocking buffers. To avoid high well to well variation, do not stack plates during incubation, no bubbles in the plate and wash wells thoroughly to avoid variation.

Upstream tips
Bring all reagents to room temperature (18-25°C) before use for 30min.
-Prepare fresh standard for each assay. Use within 4 hours and discard after use.
-Centrifuge the sample again after thawing before the assay.
Protocol tips
-To ensure accurate results, proper adhesion of plate sealers during incubation steps is necessary. Do not allow wells to sit uncovered for extended periods between incubation steps.
-Once reagents have been
added to the well strips, DO NOT let the strips DRY at any time during the assay.
-TMB Substrate should remain colorless or light blue until added to the plate. Please protect it from light.
-Stop Solution should be added to the plate in the same order as the TMB Substrate.
HO-1 (rat), ELISA kit

Enzo Life Sciences

Upstream tips
-All components of this kit except the standard are stable at 4˚C.
The standard must be stored at or below -20˚C.
-Bring all reagents except the
standard and assay buffer to
room temperature for at least
30 minutes prior to opening.
Protocol tips
-Diluted standards and samples should be kept on ice and used within 60 minutes of preparation for optimal performance. If ice is not available, diluted standards and samples should be used within 20 minutes of preparation.
-Prior to the addition of antibody, conjugate or substrate, ensure there is no residual wash buffer in the wells. Remaining wash buffer may cause variation in assay results.
Upstream tips
-Bring all reagents to room temperature before use. Allow all components to sit for a minimum of 15 minutes with gentle agitation after initial reconstitution.
-Working dilutions should be prepared and used immediately.
Protocol tips
-A standard curve should be generated for each set of samples assayed.
-It is suggested to start Reagent Diluent optimization for serum and plasma samples by using PBS supplemented with 10-50% animal serum.
-Do not use buffers with animal serum to reconstitute or dilute the Detection Antibody or Streptavidin-HRP B.
