Pricing and Online Ordering at www.alphalabs.co.uk Clinical Chemistry Kappa and Lambda light chains (Turbidimetric) For the quantitative immunoturbidimetric determination of bound and free kappa or lambda light chains in serum and plasma. In healthy individuals the ratio between kappa and lambda in serum is normally around 2:1. In case of monoclonal gammopathy, this ratio is altered because there is expansion in either a kappa- or lambda-producing clone that produces a high quantity of homogeneous free light chains. n Dual liquid-stable reagent n Measuring range: Kappa light chains: 70-1600 mg/dL Lambda light chains: 40-1000 mg/dL n Open-vial stability: 120 days when stored at 2-8C Technical information: The determination is based on a turbidimetric reaction between a specific polyclonal antiserum and light chains in the presence of polyethylenglycol polymer (PEG). The change in absorbance caused by the immuno-complex is proportional to the concentration of the analyte in the sample.

Iron exists in biological fluids as a component of haemoglobin and myoglobin as well as bound to transferrin (for transport in plasma) and ferritin (for storage). Increased iron concentrations occur in haemochromatosis and liver damage. Decreased iron levels (anaemia) can be caused by malabsorption as consequence of gastrointestinal diseases or by blood loss as a result of gastrointestinal lesions or heavy menstrual bleeding. For the estimation of the body iron status, the measurement of transferrin and ferritin can also provide additional information. n Dual liquid-stable reagent n Linearity: up to 1000 μg/dL n Open-vial stability: 90 days when stored at 2-8C n Includes standard Technical information: At pH 4.8, bound iron is released from transferrin and then quantitatively reduced to a ferrous state. Divalent iron forms a stable coloured complex with Ferene S {3-(2-pyridil)-5,6-bis-2-(5-furylsulfonic acid)-1,2,4- triazine}, the intensity of which is proportional to the amount of iron in the sample. Interference from copper is eliminated by particular reaction conditions and a specific masking agent.
