Components Reagent A: 30 mL. Reagent B: 10 mL. Reagent C: 30 mL. Saline: 50 mL. Calibrator: 2 mL (equivalent to 5 mg/dL Bilirubin).
Material not included Pipeting devices and accessories, 96-well plates and plate reader.
Background Quantitative determination of bilirubin by colorimetric (530nm) method.
Procedure: 10 min.

Bilirubin is one of the degradation products of hemoglobin formed when red blood cells die. Bilirubin exists in the insoluble unconjugated form (also indirect bilirubin), or soluble glucuronide conjugated form bilirubin (also direct bilirubin). Conjugated bilirubin moves into the bile canaliculi of the liver and then to the gall bladder. When stimulated by eating, bile (including the conjugated bilirubin) is excreted into the small intestine, where bilirubin is converted into urobilinogen. Bilirubin is a key diagnostic indicator. High levels of bilirubin result when too much hemoglobin is broken down or the removal of bilirubin does not function properly. The accumulation of bilirubin in the body causes jaundice. Simple and automation-ready procedures for quantitative determination of bilirubin find wide applications in research and drug discovery. This bilirubin assay kit is designed to measure bilirubin in blood specimen in 96-well or cuvette formats. The improved Jendrassik- Grof method utilizes the reaction of bilirubin with diazotized sulfanilic acid, in which a red colored product is formed. The intensity of the color, measured at 510-550nm, is an accurate measure of the bilirubin level in the sample. Total bilirubin is assessed using caffeine benzoate to split bilirubin from the unconjugated bilirubin protein complex.
Application Notes Direct Assays: total and direct bilirubin in serum or plasma.
Pharmacology: effects of drugs on bilirubin metabolism.
Protocol Procedure using 96-well plate:
1. Reagent Preparation: prepare at least 200 L/well. Total Bilirubin is determined with Working Reagent that contains Reagent C, and Direct Bilirubin with Working Reagent that does not contain Reagent C but saline instead.
2. Calibrator: transfer 50 L H2O and 50 L Calibrator into two wells of clear-bottom 96-well plate, add 200 L H2O. The volume in each well 250 L. Samples: transfer 50 L sample into separate wells, add 200 L respective Working Reagent (i.e. for total bilirubin and/or direct bilirubin) and 200 L Blank Reagent to the sample wells.
3. Incubate 10 min and read OD530nm (510 to 550nm).

Procedure using Cuvet:
1. Prepare at least 800 L/well fresh Working Reagent.
2. Transfer 200 L H2O and 200 L Calibrator into two cuvets, add 800 L H2O. Transfer 200 L sample into cuvet, add 800 L Working Reagent.
3. Incubate 10 min and read OD530nm (510 to 550nm).
