ELISA Mouse - HSP70

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 before use.
-Reconstitute the Human Cytochrome c Standard with deionized or distilled water. Allow the standard to sit for a minimum of 15 minutes with gentle agitation prior to making dilutions.
Protocol tips
-When mixing or reconstituting protein solutions, always avoid foaming.
-Keep Substrate solution protected from light.
-Stop Solution should be added to the plate in the same order as the Substrate Solution. The color developed in the wells will turn from blue to yellow upon addition of the Stop Solution.
Upstream tips
-All ELISA reagents must be at room temperature (20-25°C) before use.
Protocol tips
-Minimize lag time between wash steps to ensure the plate does not become completely dry during the assay.
-Use a new adhesive plate cover for each incubation step.
-Take care not to contaminate the TMB Substrate. Do not expose TMB Substrate
solution to glass, foil, or metal. If the solution is blue before use, DO NOT USE IT.
Upstream tips
-Equilibrate all reagents to room temperature (18-25°C) prior to use.
Protocol tips
-Avoid foaming or bubbles when mixing or reconstituting components.
-Ensure plates are properly sealed or covered during incubation steps.
-Complete removal of all solutions and buffers during wash steps is necessary to minimize background.
Downstream tips
-Unused well strips should be returned to the plate packet and
stored at 4°C.
