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. Add Incubation Buffer to all wells except the chromogen blank.
2. Add the standard, buffer solution, or cell culture medium sample to the appropriate wells. for
Serum and control samples, add standard dilution buffer, then add samples to
suitable well. Leave the chromogen blank holes blank.
3. Tap the side of the plate to mix. Cover the plate with a plate lid and incubate at room temperature for 2-3 hours.
4. Aspirate the solution thoroughly and wash the wells 4 times with wash buffer.
5. Add Biotin Conjugate solution to each well except the chromogen blank.
6. Cover the plate and incubate at room temperature for 1-2 hours.
7. Aspirate the solution thoroughly and wash the wells 4 times with wash buffer.
8. Add Streptavidin-HRP solution to each well except the chromogen blank.
9. Cover the plate with a plate cover and incubate at room temperature.
10. Aspirate the wells thoroughly and wash the wells 4-6 times with wash buffer.
11. Add stable chromogen to each well. The substrate solution begins to turn blue.
12. Incubate at room temperature for 30-45 minutes in the dark.
13. Add stop solution to each well. Tap the side of the plate to mix. The solution in the well changed from blue to yellow.

1. Read the absorbance at 450nm. Read the plate within 2 hours 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.
