1. Collect samples in pyrogen/endotoxin-free tubes.
2. If the sample cannot be tested immediately after collection, freeze the sample. Freeze samples to avoid multiple freeze-thaw cycles. Thaw completely and mix well (do not vortex) prior to analysis.
3. Avoid using hemolytic or blood lipid serum. If a large amount of particulate matter is present in the sample, centrifuge or filter the sample prior to analysis.

1. Determine the number of microbars required for the number of samples required for testing and the appropriate number of holes required for running blanks and standards. Measurements should be repeated for each sample, standard sample, blank sample, and optional control sample. Remove the excess microstrip from the holder and store in an aluminum foil bag sealed with a desiccant provided from 2°C to 8°C.
2. Wash the microporous bar twice with washing buffer for each well, and thoroughly suck out the microporous contents between two washes. Allow the wash buffer to sit in the hole for about 10-15 seconds before suction. Be careful not to scratch the surface of the micropores. After the last washing step, empty the holes and tap the microstrip on an absorbant pad or paper towel to remove excess Wash buffer.
3. Standard dilution on microplate: Add calibration dilution to all standard holes in duplicate. Standard for preparation of pipette, in duplicate, in two separate Wells. The contents of the two Wells were mixed by repeated pumping and ejection and transferred to the other two Wells separately. Be careful not to scratch the inner surface of the micropores. Continue this process 6-8 times to create two rows of standard diluents. Discard the contents of the last microhole.
4. Add the calibration diluent in duplicate to the blank well.
5. Add sample thinner to sample well.
6. Add each sample in duplicate to the sample well.
7. Prepare biotin conjugates according to the manual.
8. Add biotin-Conjugate to all Wells.
9. Cover with a sticky film and incubate on a microplate oscillator at room temperature (18°C to 25°C) for 2-3 hours.
10. Prepare Streptavidin-HRP according to the operation manual.
11. Remove the film and empty the hole. Clean the microstrip 6-8 times according to the operation manual.
12. Add diluted Streptavidin-HRP to all the well, including the blank well.
13. Cover with a sticky film and incubate on a microplate oscillator at room temperature (18°C to 25°C) for 1-2 hours.
14. Remove film and empty holes. Clean the microstrip 6-8 times according to the operation manual.
15. Move TMB substrate solution into all Wells.
16. Incubate the micropores at room temperature (18°C to 25°C) for 10-30 minutes. Avoid direct exposure to the light. Color development on the plate should be monitored and the substrate reaction stopped before positive Wells are no longer properly recorded. The ideal chromogenic time period must be determined separately for each assay.
17. Stop the enzyme reaction by rapidly draining the stop solution into each well. It is important to stop the solution distributing quickly and evenly throughout the micropore to completely inactivate the enzyme. The results must be read immediately after adding the termination solution, or within 1 hour if the microstrip is stored at 2°C to 8°C in dark.
18. Read the absorbance of each micropore on a spectrophotometer, using 450 nm as the main wavelength (620 nm as the reference wavelength is optional; 610 nm to 650 nm is acceptable). Use blank holes to blank the reader according to the manufacturer's instructions. Determine absorbance of sample and standard.

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.

CSF2; GMCSF; colony stimulating factor 2; CSF

It is a cytokine that controls the production, differentiation, and function of granulocytes and macrophages. The active form of the protein is found extracellularly as a homodimer. This gene has been localized to a cluster of related genes at chromosome region 5q31, which is known to be associated with interstitial deletions in the 5q- syndrome and acute myelogenous leukemia. Other genes in the cluster include those encoding interleukins 4, 5, and 13. This gene plays a role in promoting tissue inflammation. Elevated levels of cytokines, including the one produced by this gene, have been detected in SARS-CoV-2 infected patients that develop acute respiratory distress syndrome. Mice deficient in this gene or its receptor develop pulmonary alveolar proteinosis.
