    DESCRIPTION 

    HEMOGLOBIN (Hb) is made of four globin chains each carrying a heme group. It is carried by red blood cells and transports oxygen from the lungs to the peripheral tissues to maintain the viability of cells. Quantitation of blood hemoglobin has been a key diagnostic parameter for various diseases such as anemia, polycythemia and dehydration. Simple, direct and automation-ready procedures for measuring hemoglobin concentration are becoming popular in Research and Drug Discovery. BioAssay Systems' QuantiChromTM Whole Blood Hb kit is based on an improved aqueous alkaline method, in which the hemoglobin is converted into a uniform colored end product. The intensity of color, measured at 570 nm, is directly proportional to hemoglobin concentration in the sample. The optimized formulation substantially reduces interference by substances in the raw samples.

    KEY FEATURES 

    Non-hazardous. No hazardous chemicals (e.g. potassium cyanide in Drabkin's Reagent) used. 

    Simple and high-throughput. The “mix-and-read” procedure involves addition of a single reagent and reading the optical density. Can be readily automated as a high-throughput assay in 96-well plates for thousands of samples per day. 

    Versatility. Assays can be executed in 96-well plate or cuvette. 

    High sensitivity. As low as 5 µL sample is used. Ideal when samples are limited such as mice blood samples.

    APPLICATIONS 

    Direct Assays: total hemoglobin in whole blood samples. 

    Pharmacology: effects of drugs on hemoglobin metabolism.  

    KIT CONTENTS (250 TESTS IN 96-WELL PLATES) 

    HB Reagent: 50 mL 

    Calibrator: 500 µL (12.0 g/dL)

    Storage conditions. The kit is shipped at room temperature. Store reagent and calibrator at 4°C. Shelf life: 12 months after receipt. 

    Precautions: reagents are for research use only. Normal precautions for laboratory reagents should be exercised while using the reagents. Please refer to Material Safety Data Sheet for detailed information  

    PROCEDURES 

    Procedure using 96-well plate: 

    Since 5 µL samples are used, when possible perform assays in duplicate or triplicate. 

    1. Carefully pipette 5 µL water (Blank), 5 µL Calibrator and 5 µL whole blood samples into wells of a clear bottom 96-well plate. 

    2. Transfer 200 µL HB Reagent into all assay wells. Tap plate to mix. 

    3. Incubate 5 min at room temperature. Read OD at 570 nm (range 560- 600 nm). OD values are stable for at least 60 min.

    Procedure using cuvette:

    1. Pipette 10 µL water (Blank), 10 µL Calibrator and 10 µL whole blood samples into separate cuvettes. 

    2. Transfer 1 mL HB Reagent into all cuvettes. Mix well. 

    3. Incubate 5 min at room temperature. Read OD at 570 nm (range 560- 600 nm). OD values are stable for at least 60 min.  

    CALCULATION

    Calculation: subtract blank OD (water) from the Calibrator and Sample OD values. The hemoglobin concentration of Sample is calculated as

    ODSAMPLE, ODCALIBRATOR and ODH2O are OD values of the sample, the Calibrator (12.0 g/dL) and water. 

    Conversions: 1.0 g/dL Hb is equivalent to 0.156 mM.

    MATERIALS REQUIRED, BUT NOT PROVIDED 

    Pipetting devices and accessories clear flat- bottom 96-well plates (e.g. VWR cat# 82050-760) or cuvettes and plate reader or spectrophotometer.
