Principle of the Assay: The ELISA (Enzyme Linked Immunosorbent Assay) is an immunoassay, which is particularly suited to the determination of antibodies in the field of infectious serology. The reaction is based on the specific interaction of antibodies with their corresponding antigen. The test strips of the microtiter plate are coated with specific antigens of the pathogen of interest. If antibodies in the sample are present, they bind to the fixed antigen. A secondary antibody, which has been conjugated with the enzyme alkaline phosphatase, detects and binds to the immune complex. The colourless substrate p-nitrophenylphosphate is then converted into the coloured product p-nitrophenol. The signal intensity of this reaction product is proportional to the concentration of the analyte in the sample and is measured photometrically!!Background/Introduction: Candida spp. are ubiquitous yeast-like fungi, which can even be demonstrated in around 75 % of all healthy individuals in the form of skin and mucous membrane colonization. They live as harmless saprophytes in the throat, trachea, stomach, and large and small intestines. The microorganisms are normally not capable of breaking the defence mechanisms of the human skin and mucous membranes and successfully challenging the immune system, but numerous risk factors may, however, significantly increase the likelihood of Candida albicans or related fungi becoming established, resulting in mycosis. Candida albicans is the primary cause of candidiasis. Yeasts of the genus Candida frequently cause infections of the mucous membranes, e. g. oral thrush, vaginal mycosis, or nappy-rash, but can also be responsible for systemic organ mycosis affecting the eyes, liver, kidneys or lungs and also be the cause of Candida septicaemia. Apart from the yeast form, which primarily causes superficial infections, so called pseudo mycelia are a further morphologic manifestation of the pathogen. Germ tubes and the development of pseudo mycelia mainly occur in cases of systemic mycosis. Candida spp. produce and excrete a range of destructive enzymes, that enable the facultative pathogenic microorganisms to penetrate mucous membrane barriers and blood vessels. In general, Candida spp. are transmitted from person to person by smear contamination. The primary portal of entry is the oral cavity. Changes in the fungistatic properties of the skin, which are a consequence of a slightly acidic pH value and the antagonistic bacterial flora, can facilitate the establishment of superficial candidiasis of the skin surface. Systemic mycosis results from colonization of mucous membranes, particularly in the gastrointestinal tract.

Product Notes
The Casp1 casp1 (Catalog #AAA495223) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "Caspase-1, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
