Kommentare:

This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-IL-8 polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-IL-8 polyclonal antibody was used as detection antibodies. The standards test samples and biotin conjugated detection antibody were added - the wells subsequently and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were used - visualize HRP enzymatic reaction. TMB was catalyzed by HRP - produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional - the IL-8 amount of sample captured in plate. Read the O.D. absorbance at 450 nm in a microplate reader and then the concentration of IL-8 can be calculated.
15.6 - 1000 pg/mL (body fluids, lysates, supernates), 7.8 - 500 pg/mL (serum, plasma)

Plattentyp: Pre-coated

Aufbereitung der Reagenzien:

1. Before the experiment, centrifuge each kit component for several minutes to bring down all reagents to the bottom of tubes. 2. It is recommend to measure each standard and sample in duplicate. 3. Do NOT let the plate completely dry at any time! Since the dry condition can inactivate the biological material on the plate. 4. Do not reuse pipette tips and tubes to avoid cross contamination. 5. Do not use the expired components and the components from different batches. 6. To avoid the marginal effect of plate incubation for temperature differences (the marginal wells always get stronger reaction), it is recommend to equilibrate the ABC working solution and TMB substrate for at least 30 min at room temperature (37 °C ) before adding to wells.The TMB substrate (Kit Component 8) is colorless and transparent before use, if not, please contact us for replacement.

Aufbereitung der Proben:

Preparation of sample and reagents 1. Sample Isolate the test samples soon after collecting, then, analyze immediately (within 2 hours). Or aliquot and store at -20 °C for long term. Avoid multiple freeze-thaw cycles.
Tissue lysate, body fluids and cell culture supernatants: Centrifuge to remove precipitate, analyze immediately or aliquot and store at -20 °C .
Serum: Coagulate the serum at room temperature (about 4 hours). Centrifuge at approximately 1000 × g for 15 min. Analyze the serum immediately or aliquot and store at -20 °C .
Plasma: Collect plasma with citrate, heparin or EDTA as the anticoagulant. Centrifuge for 15 min at 1000 x g within 30 min of collection. Analyze immediately or aliquot and store frozen at -20 °C. Note: 1. Coagulate blood samples completely, then, centrifuge, and avoid hemolysis and particle. 2. NaN3 can not be used as test sample preservative, since it is the inhibitor for HRP.

Details zu IL-8

Target: IL-8 (IL8) (Interleukin 8 (IL8))

Andere Bezeichnung: IL-8

Hintergrund: Interleukin-8 (IL8) is a member of the CXC chemokine family. It is proinflammatory and primarily mediates the activation and migration of neutrophils into tissue from peripheral blood. It produced by macrophages, and also synthesized by endothelial cells. IL-8 is one of the major mediators of the inflammatory response. It is secreted by several cell types. It functions as a chemoattractant, and is also a potent angiogenic factor. Primary function of IL-8 is the induction of chemotaxis in its target cells, and it also recruits neutrophils to phagocytose the antigen, which triggers the antigen pattern toll-like receptors. IL-8 is often associated with inflammation. As an example, it has been cited as a proinflammatory mediator in gingivitis and psoriasis.
