hs-CRP ELISA Kit (C-Reactive Protein)

INTENDED USE

Human hs-CRP ELISA kit is a method for analysing in vitro quantitative high sensitive concentrations c-reactive protein (hs-CRP) in human serum and plasma. This assay has a minimum detection limit of < 0.02 µg/ml.

BACKGROUND

C-reactive protein (CRP) has a total approx. molecular mass of 120.000 Daltons and is made up of a symmetrical pentamer structure. It is essentially a kind of non-immunoglobulin serum substance which is also a heat labile beta-globulin. The levels can increases dramatically after microbial infections and this property has been particularly helpful for the diagnosis and monitoring a large number of bacterial septicemia in neonates and in many other immune-compromised patients.

The concentrations of CRP begins to rise within 6 hours of an acute inflammatory challenge. Also, many injuries that are responsible for causing necrosis and tissue breakdown are also found to elevate serum levels, examples of these are observed in major surgery, myocardial infarction and thermal burns.

CONTENT

All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

• Coated Microtiterstrips: Coated with monoclonal antibodies to human CRP.
• Standards (A-E): Concentrations 0, 0.4, 1, 5, 10 µg/ml.
• Enzyme Conjugate.
• Specimen Dilution Buffer (5x).
• Washing Solution (20x).
• TMB Chromogen Solution.
• Stopping Solution.

SENSITIVITY

The minimum detection sensitivity level of high sensitive c-reactive protein (CRP) using this hs-CRP ELISA kit was 0.02 µg/ml. The dynamic assay range for this kit is 0.4 – 10.0 µg /ml.

ASSAY CHARACTERISTICS

– Analytical Sensitivity: 0.02 µg/ml
– CRP values < 1.0 mg/L = Low risk for CVD.
-CRP values 1.0 – 2.9 mg/L = Intermediate risk for CVD
– CRP values > 3.0 mg/L = High risk for CVD
– Intra Assay Precision: 4.1 – 6.9%
– Inter Assay Precision: 5.8 – 6.3%
– Cross-Reactivity: Recognizes natural and recombinant human CRP.
