ELISA Mouse - PRL

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
-The entire kit may be stored at -20°C for up to 1 year from the date of shipment.
-Avoid repeated freeze-thaw cycles.
-The kit may be stored at 4°C for up to 6 months.
-Bring all reagents and samples to room temperature (18 - 25ºC) before use.
Protocol tips
-Levels of Dkk-1 may vary between different samples.
Optimal dilution factors
for each sample must be determined by the investigator.
-A standard curve must be run with each assay.
-Keep substrate solution protected from light.
-Read immediately after adding STOP solution.
Downstream tips
-Store your standard at <-70ºC after reconstitution, others at 4ºC.
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.
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.
