Browse all PicoKine™ ELISA KitsWhat is an ELISA Kit?
ELISA kits are ready-to-use immunoassay kits that contain all reagents required to perform ELISA (Enzyme-Linked Immunosorbent Assay). ELISA is a plate-based experiment designed to detect and quantify molecules, such as proteins, antibodies, hormones, peptides and sometimes small molecules like vitamins and coenzymes. Antibodies linked with enzymes are used to quantify the results. Various formats (see below) exist and in each one the antibody antigen interaction principle is different.

How does ELISA kit work?
The key step, immobilization of the antigen of interest, can be accomplished by direct adsorption to the assay plate or indirectly via a capture antibody that has been attached to the plate. The antigen is then detected either directly (enzyme-labeled primary antibody) or indirectly (enzyme-labeled secondary antibody). The detection antibodies are usually labeled with alkaline phosphatase (AP) or horseradish peroxidase (HRP). A large selection of substrates is available for performing the ELISA with an HRP or AP conjugate. The choice of substrate depends upon the required assay sensitivity and the instrumentation available for signal-detection (spectrophotometer, fluorometer or luminometer). Detection is achieved by measuring the enzyme activity. One method is through incubation with TMB substrate which can be detected via the converted substrate’s light absorbance at 450nm. Alternatively the enzyme can catalyze Chemiluminescent substrate, triggering a strong luminescent reaction which can be quantified.
Typical ELISA Protocol Workflow
Nemametrix provide a streamlined immigration case management software. Case management shouldn’t take hours. So we designed it to be easy. With the following simple steps, all your documents will fall in the right place, so your team can focus on the things that matter :
-
Coating
Polystyrene plate is treated with a solution of either antigen or antibody.
-
Blocking
An unrelated protein-based solution is used to cover all unbound sites on the plates.
-
Detection
Enzyme-conjugated antibody or antigen binds specifically to the target antigen or antibody.
-
Read Results
Substrate is added and the signal produced by the enzyme-substra reaction is measured.

what life scientists are saying about Boster ELISA kits
"We are a pharmaceutical startup optimizing cell based drug assays where one of our endpoints was observing the differences in mature IL-1b production in the media. I have compared several kits from the most expensive versions of R&D, over eBioscience/Affymetrix to a more budget Boster's kit. The aim was to decide..

I was using this kit to detect IL-2 secretion from Jurkat T-cells upon activation with PMA and PHA. I followed the protocol exactly. I had extremely low levels of IL-2 in my experiment, which were just above background. In this case, it was essential for me to use the standards and blanks...

A number of problems commonly arise during ELISA that can result in low signal and poor color development. Use are some troubleshooting tips to help you improve your experiment and get better data. For more information, visit ELISA Troubleshooting Low Signal.
Matrix Effect occurs when the target antigen interacts with matrix components in plasma or serum samples. These matrix components can be endogenous biological components such as phospholipids, carbohydrates, and metabolites. Matrix components can reduce the binding of the antibody to the target protein, or non-specifically bind the antibody, generating weak or noisy results. Read some tips to reduce matrix effect.
On each 96 well plate, we recommend running an 8-point standard curve with duplicate wells. With the remaining 80 wells, 40 samples can be tested in duplicate. Learn more about the number of samples tested per micotiter plate.
Yes the ELISA kit plate is separable if the kit description says that there are removable strips. There are 12 strips of 8 wells each, all removable from the plate.
Our Elisa kits contain 0.02% Sodium Azide. All of the components except TMB colour developing reagent and stop solution contains 0.02% Sodium azide as the preservative.
The kit can be used within a month sequentially if it's opened and stored at 4 degree. There is no need to use sealants, the plate can be packaged with aluminum foil bag, and for other reagents keep bottle tightly closed.
This information can be found for each kit under the "Properties" section, and you can find the immunogen sequence information in the "Overview" section.
Our Elisa kits do not come with wash solution, but we have included information about how to make washing buffer on the datasheet. Please refer to the "Material Required But Not Provided" section. We also offer washing buffer for sale separately (Phosphate Buffered Saline Powder SKU: AR0030).
The well depth is 300ul, and the max capacity is 350ul. The height of the well is 1.1 cm, and the internal size is 1 cm.

We test serum and plasma routinely, and there is very little difference between serum, plasma and whole blood. The whole blood also contains proteins we need to test. The kit can be used to test whole blood in theory.
It means Avidin-Biotin-Peroxidase Complex(AR1103) and you could find it in Kit Components.
None of the components in our ELISA kits are produced in humans or primates.
Our kits would work normally with samples from Wistar Rat.
For tissue homogenates, endogenous biotin should be considered. Endogenous biotin in tissue homogenates might introduce false positive signal. Please run the test as described below to confirm if there is Endogenous biotin in the tissue lysate samples using the ELISA kit.
• Add tissue homogenates into the wells and then add ABC and TMB without adding any biotinylated detection antibody to see if any signal will be observed.
If no signal is produced, then you can work on the tissue sample by using the kit.
• Add tissue homogenates into the wells and then add ABC and TMB without adding any biotinylated detection antibody to see if any signal will be observed.
If no signal is produced, then you can work on the tissue sample by using the kit.
Our kits should still be stable after being in ambient temperatures for around 5 days. It would not affect the performance of the kit. We suggest you to run the test and contact us if does not work as expected.
The bubbles in the wells is an uncommon issue, but it would not affect the results of your experiment. We suggest to wash the plate to remove the bubbles as suggested in the protocol below prior to the assay: Wash the plate 3 times with the 1X wash buffer. Discard the liquid in the wells into an appropriate waste receptacle. Then, invert the plate on the benchtop onto a paper towel and tap the plate to gently blot any remaining liquid. It is recommended that the wells are not allowed to completely dry at any time. Add 300 µl of the 1x wash buffer to each assay well. (For cleaner background incubate for 60 seconds between each wash). Repeat steps a-b 2 additional times.
