ELISA Mouse - SDF-1/CXCL12

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
-Store the unopened kit at 2-8 °C.
-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.
-Substrate Solution should remain colorless until added to the plate.
-Keep Substrate solution protected from light.
-Stop Solution should be added to the plate in the same order as the Substrate Solution.
-Wells that are green in color indicate that the Stop Solution has not mixed thoroughly with
the Substrate Solution.
Upstream tips
-Bring all reagents and samples to room temperature (18–25 °C)
before use.
Protocol tips
-Wash by filling each well with Wash Buffer (300 µl) using a
multi-channel Pipette or autowasher. Complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Buffer by aspirating or decanting. Invert the plate and blot it against clean paper towels.
-Read at 450 nm immediately after adding STOP solution.
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.
