96 well plate

1. The buffer concentrate should be brought to room temperature and diluted before starting the test procedure.
2. If crystals form in the buffer concentrate, heat gently until the crystals are completely dissolved. See the kit manual for the rest.

1. For the standard curve, add the standard to the corresponding hole. For sample, add diluted sample to the well.
2. Cover well and incubate at room temperature for 2-4 hours or gently shake at 4°C overnight.
3. Discard the solution and wash it 3-5 times with 1X wash buffer. Use a multi-channel pipette or automatic cleaner to fill each hole with a cleaning buffer. Complete liquid removal at each step is essential for good performance. After the last wash, remove any remaining wash buffer by suction or decanting. Turn the board upside down and drain with a clean paper towel.
4. Add the prepared biotin conjugates into each well.
5. Incubate gently at room temperature for 1-2 hour.
6. Discard the solution. Repeat the washing in Step 3.
7. Add the prepared Streptavidin-HRP solution to each well.
8. Incubate gently at room temperature, shaking for 30-50 minutes.
9. Discard the solution. Repeat the washing in Step 3.
10. Add TMB substrate to each well. The substrate will begin to turn blue.
11. Incubate at room temperature, dark, for 30-45 minutes, shaking gently.
12. Add termination solution to each well. Tap lightly on the sides of the boards to blend. The solution in the hole changes from blue to yellow.

1.Calculate the mean absorbance values for each set of replicate standards and samples.
2. Create a standard curve by plotting the mean absorbance of each standard concentration on the ordinate and the monkey IL-2 concentration on the abscissa.
3. To determine the circulating monkey IL-2 concentration for each sample, first find the mean absorbance value on the ordinate and extend a horizontal line onto the standard curve.
4. At the intersection, the vertical line is extended to the abscissa and the corresponding monkey IL-2 concentration is read.
5. The sample has been diluted, so the concentration read from the standard curve must be multiplied by the dilution factor.

IL2; IL-2; TCGF; lymphokine; interleukin 2

Interleukin-2 (IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system. It is a 15.5-16 kDa protein that regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity. IL-2 is part of the body's natural response to microbial infection, and in discriminating between foreign ("non-self") and "self". IL-2 mediates its effects by binding to IL-2 receptors, which are expressed by lymphocytes. The major sources of IL-2 are activated CD4+ T cells and activated CD8+ T cells.
