1. Prepare Wash Buffer
Allow wash buffer concentrate to reach room temperature and mix to redissolve any precipitated salts. Dilute Wash Buffer Concentrate into deionized or distilled water. Store the concentrate and 1X wash buffer in the refrigerator.
2. Prepare the thinner
The test diluent should be diluted with deionized or distilled water before use.
3. Preparation of Biotin Conjugation
Spin the biotin conjugate briefly before use. Gently stir up and down with a pipette. Collect samples in pyrogen/endotoxin-free tubes. If samples cannot be tested immediately after collection, freeze samples. Freeze samples to avoid multiple freeze-thaw cycles.
4. Pre-dilute samples
For different types of samples, different dilution solutions should be used for dilution.
5. Prepare 1X Streptavidin-HRP Solution
Quickly swirl Streptavidin-HRP before use and mix gently up and down with a pipette as a precipitate may form during storage. Do not store the diluted solution for future use.
6. Dilution Standards
Dilute standards using glass or plastic tubes. Simply spin off a vial of lyophilized standards.

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. Read the absorbance at 450nm. Read the plate within 30 minutes of adding the stop solution.
2. Generate a standard curve using curve fitting software.
3. Read the concentrations of unknown samples and controls from the standard curve. The sample dilution is corrected by an appropriate factor, resulting in a number of values (s) for the sample.

IL3; interleukin 3; IL-3; MCGF; MULTI-CSF

Interleukin 3 (IL-3), also called Mast Cell Growth Factor (MCGF), Multi-Colony Stimulating Factor (multi-CSF), or Eosinophil-CSF (E-CSF), is produced by activated T cells, mast cells and eosinophils. IL-3 is a hematopoietic growth factor that stimulates colony formation of erythroid, megakaryocyte, neutrophil, eosinophil, basophil, mast cell and monocytic lineages. Most of these functions are enhanced or dependent on co-stimulation with other cytokines. Human and mouse IL-3 share only 29% sequence identity at the amino acid level. The bioactivity of IL-3 is highly species specific. For example, human IL-3 has no activity on mouse cells. IL-3 is a potent growth promoting cytokine. IL-3 is capable of supporting the proliferation of a broad range of hematopoietic cell types, and is involved in a variety of cell activities such as cell growth, differentiation and apoptosis. IL-3 has been shown to also possess neurotrophic activity, and it may be associated with neurologic disorders.
