Specimen Collection
Serum Allow serum to clot for 10-20 minutes at room temperature. Centrifuge at 2000-3000 RPM for 20 minutes.
Plasma Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples for 15 minutes at 2000-3000 RPM at 2 - 8°C within 30 minutes of collection.
Urine Collect by sterile tube. Centrifuge at 2000-3000 RPM for approximately 20 minutes. When collecting pleuroperitoneal fluid and cerebrospinal fluid, please follow the procedures above-mentioned.
Cell Culture Supernatant Collect by sterile tubes when examining secrete components. Centrifuge at 2000-3000 RPM for approximately 20 minutes. Collect the supernatants carefully. When examining the components within the cell, use PBS (pH 7.2-7.4) to dilute cell suspension to the cell concentration of approximately 1 million/ml. Damage cells through repeated freeze-thaw cycles to let out the inside components. Centrifuge at 2000-3000 RPM for approximately 20 minutes.
Tissue Rinse tissues in PBS (pH 7.4) to remove excess blood thoroughly and weigh before homogenization. Mince tissues and homogenize them in PBS (pH7.4) with a glass homogenizer on ice. Thaw at 2-8°C or freeze at -20°C. Centrifuge at 2000-3000 RPM for approximately 20 minutes.
Reagent Preparation
All reagents should be brought to room temperature before use.
Standard Reconstitute the 120μl of the standard (48ng/L) with 120μl of standard diluent to generate a 24ng/L standard stock solution. Allow the standard to sit for 15 mins with gentle agitation prior to making dilutions. Prepare duplicate standard points by serially diluting the standard stock solution (24ng/L) 1:2 with standard diluent to produce 12ng/L, 6ng/L, 3ng/L and 1.5ng/L solutions. Standard diluent serves as the zero standard(0 ng/L). Any remaining solution should be frozen at -20°C and used within one month. Dilution of standard solutions suggested are as follows:
| 24ng/L | Standard No.5 | 120μl Original Standard + 120μl Standard Diluent |
| 12ng/L | Standard No.4 | 120μl Standard No.5 + 120μl Standard Diluent |
| 6ng/L | Standard No.3 | 120μl Standard No.4 + 120μl Standard Diluent |
| 3ng/L | Standard No.2 | 120μl Standard No.3 + 120μl Standard Diluent |
| 1.5ng/L | Standard No.1 | 120μl Standard No.2 + 120μl Standard Diluent |
| Standard Concentration | Standard No.5 | Standard No.4 | Standard No.3 | Standard No.2 | Standard No.1 |
| 48ng/L | 24ng/L | 12ng/L | 6ng/L | 3ng/L | 1.5ng/L |
Wash Buffer Dilute 20ml of Wash Buffer Concentrate 30x into deionized or distilled water to yield 500 ml of 1x Wash Buffer. If crystals have formed in the concentrate, mix gently until the crystals have completely dissolved.
Summary
Wash the plate 5 times.
Add substrate solution A and B. Incubate for 10 minutes at 37°C.
Add stop solution and color develops.
Read the OD value within 10 minutes.
