Description
Technical field
The invention belongs to medical immunology in-vitro diagnosis field, relate to a kind of immunologic function test reagent, further, the present invention relates to a kind of IGY of utilization sections protein antibodies, the liquid double reagent kit through ferritin in the latex enhancing immune turbidimetry for Determination serum.
Background technology
Extensively there is one type of albumen of storing iron in the animal and plant body; Content is maximum in the liver of mammal and spleen; About 12～the 14nm of its external diameter, the empty pocket chamber directly is about 6nm, and shell (being apoferritin) is made up of 24 subunits; Each subunit contains 163 amino acid residues approximately, and each molecule can combine 4500 iron atoms at most.Molecular weight is about 900,000.Ferritin in conjunction with iron be " dissolving " in water, the iron that stores in the concentration of blood plasma ferritin and the body is directly proportional.
Ferritin is a kind of solvable histone of storing iron in the body.Contain small amounts of iron albumen in the normal human serum, but the different detection method there is different normal values.The general about 80-130 μ of normal mean value male sex g/L (80-130ng/ml) women about 35-55 μ g/L (35-55ng/ml).The serum levels of iron level reduces when the gestational period and acute anemia, raises when acute and chronic liver damage and liver cancer, and domestic report liver cancer patient positive rate is up to 90%.Discovered in recent years liver cancer also contains a kind of isoferritin of acidity, is called cancer embryo isoferritin, has the early diagnosis of helping.The reason that liver cancer patient has ferritin to increase possibly be: 1. HCC can synthesize and secrete ferritin or isoferritin; 2. liver cancer tissue is affected to the picked-up and the removing of ferritin; 3. hepatocellular damage is downright bad, and the ferritin that is stored in the liver cytoplasm overflows in the blood.Though serum ferritin is non-specific, except that liver cancer, cancer of pancreas moderate raise, other tumor in digestive tract such as the cancer of the esophagus, cancer of the stomach, straight colon cancer did not all raise.Liver cancer patient treatment responder serum ferritin descends, and raises and worsen and do not send out the person again, continues to increase then prognosis mala, can be used as one of curative effect monitoring means so serum ferritin is measured, and is particularly meaningful especially to the AFP negative patients.
