Complement Pathway ELISA Kit [Pig], 3 x 96 det. (CAT#: CB-P116-K) Datasheet

Product Type
The innate immune system is important in the important defense against foreign pathogens. The main component of this response is the complement system. The complement system consists of a complex family of proteins and receptors, which are found in the circulatory system, tissues and other body fluids. Today, some connections with adaptive immunity are also described. The system consists of three defined pathways, which are activated by pathway-specific molecules. Complement activation proceeds in a sequential manner through the proteolytic cleavage of a series of proteins, resulting in the production of activation products that mediate various biological activities through interactions with specific cell receptors and other serum proteins. These three pathways are the classical pathway, the lectin pathway and the alternative pathway, which converge into the final universal pathway at the central component. That is, the activation of C3 leads to the formation of C3a and C3b. This cleavage activates the terminal complement pathway, which ultimately leads to the formation of the terminal C5b-9 complement complex (TCC). The alternative pathway is initiated by the binding of C1q to the antibody complex, while the alternative pathway and the lectin pathway are through the interaction of complement components with specific carbohydrate groups and lipopolysaccharide (LPS) on the surface of the foreign pathogen to The antibody is activated in an independent manner. Alternative pathways also serve as amplification loops for other pathways. Under certain conditions, the complement system may be detrimental to the host, causing for example. Autoimmune diseases and infections. The lack of C3 is, for example, related to SLE. Changes in alternative pathways, such as properdin or fibronectin deficiency, can increase susceptibility to infection. Mannose-binding lectin (MBL) is the main component of the lectin pathway and is related to bacterial, fungal and viral infections. One common method for measuring the activity of alternative pathways or alternative pathways is hemolysis of red blood cells. In addition, several assays have been described to measure the activity of the MBL pathway. Not all determinations are easy to perform. By using a combination of specialized coatings and buffers, the rat approach ELISA is easy to use and specific. Complement defects or other defects in the complement system can be easily screened by analyzing each pathway in parallel or separately.
Porcine complement pathway ELISA is a qualitative/semi-quantitative ELISA for in vitro determination of the activation of the classical pathway, lectin pathway and alternative pathways of the complement system in serum and plasma samples.
The kit contains three complementary pathway assays:

CB-P121-K-Alternative complement pathway assay kit [Pig]
3 x 96 det.
Detection Method
Enzyme immunoassay (ELISA) technique
Serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids
Specimen Collection
Blood samples were collected using sterile venipuncture techniques, and serum was obtained using standard procedures. At least 5 ml of whole blood is recommended. Let the blood clot in the serum test tube for 60-65 minutes at room temperature (20-25°C). Centrifuge the blood sample and transfer the cell-free serum to a clean test tube. The serum must be handled correctly to prevent complement activation in vitro. Serum should be frozen in a sealed tube at -70°C or lower for long-term storage or transport on dry ice. The sample should not be frozen and thawed more than once. Do not use jaundice, lipemia and hemolytic serum. You cannot use heat-inactivated serum. Plasma cannot be used.
Sample Volume
100 µl/well
The ELISA contains a positive control which can be used as process control to ensure that the complement cascades has run completely.
