Biosystems immunoglobulin M reagent PRINCIPLE OF THE METHOD
Immunoglobulin M in the sample precipitates in the presence of anti-human immunoglobulin M
The light scattering of the antigen-antibody complexes is proportional to the immunoglobulin M concentration and can be measured by turbidimetry1,2
Store at 2-8ºC.
The Reagent is stable until the expiry date shown on the label when stored tightly closed and if
contaminations are prevented during its use.
Indications of deterioration: Presence of particulate material, turbidity, absorbance of the blank
over 0.200 at 340 nm.
− Protein Calibrators (BioSystems cod. 31075). The set contains 5 different levels of IgM
concentration and it should be used to prepare the calibration curve. The calibrators are
supplied ready to use.
Biosystems immunoglobulin M reagent REAGENT PREPARATION
Reagent is provided ready to use.
− Thermostatic water bath at 37ºC.
− Analyzer, spectrophotometer or photometer with cell holder thermostatable at 37ºC and able
to read at 340 ± 20 nm.
Serum or plasma collected by standard procedures. Use heparin or EDTA as anticoagulants.
Lipemic samples are not suitable for testing.
Serum or plasma IgM is stable for 7 days at 2-8°C.
Biosystems Coagulation reagents include the main diagnostic tests and they are characterized by high stability and a good performance using low volume consumption.
These reagents can be performed in semiautomatic and automatic coagulation instruments, independently of the kind of clot detection method (optical and mechanic).
