Candida albicans IgM ELISA, 96 wells

Introduction
The DRG Candida albicans IgM Enzyme Immunoassay Kit provides materials for the qualitative and semiquantitative determination of IgM-class antibodies to Candida albicans in serum. This assay is intended for in vitro use only.

Principle Of The Test
The DRG Candida albicans IgM ELISA Kit is a solid phase enzyme-linked immunosorbent assay (ELISA)
Patient samples are diluted with Sample Diluent and additionally incubated with IgG-RF-Sorbent, containing hyperimmune
anti-human IgG-class antibody to eliminate competitive inhibition from specific IgG and to remove rheumatoid
factors. This pretreatment avoids false negative or false positive results.
Microtiter wells as a solid phase are coated with Candida albicans antigen.
Pretreated patient specimens and ready-for-use controls are pipetted into these wells. During incubation Candida
albicans-specific antibodies of positive specimens and controls are bound to the immobilized antigens.
After a washing step to remove unbound sample and control material horseradish peroxidase conjugated anti-human IgM
antibodies are dispensed into the wells. During a second incubation this anti-IgM conjugate binds specifically to IgM
antibodies resulting in the formation of enzyme-linked immune complexes.
After a second washing step to remove unbound conjugate the immune complexes formed (in case of positive results) are
detected by incubation with TMB substrate and development of a blue color. The blue color turns into yellow by stopping
the enzymatic indicator reaction with sulfuric acid.
The intensity of this color is directly proportional to the amount of Candida albicans-specific IgM antibody in the patient
specimen. Absorbance at 450 nm is read using an ELISA microtiter plate reader.
