Information about IFN-α ELISA Kit



Interferon and adjacent and uninfected cells can form has a special molecules made up of nucleotides, the molecules can activate ribonucleic acid hydrolase (RNAseL), L L ribonucleic acid hydrolase can destroy the full of virus RNA in the cell. At the same time, interferon can also be activated protein kinase, unfinished viral proteins in cells to destroy.
Interferon (IFN) belong to the glycoprotein. Found in humans, a total of alpha, beta, gamma three types: type of alpha interferon (IFN - alpha) is produced by white blood cells. Beta interferon (IFN - beta) is produced by the fibroblasts (fibroblast); Type gamma interferon (IFN - gamma) by T cells and natural killer cells in the immune system. All these three are effective virus inhibitors, and have certain anti-cancer effect.

The introduction of the Fibrinogen ELISA KIT



Fibrinogen (factor I) is a soluble, 340 kDa plasma glycoprotein, that is converted by thrombin into fibrin during blood clot formation. Fibrinogen is synthesized in the liver by the hepatocytes. The concentration of fibrin in the blood plasma is 200–400 mg/dL (normally measured using the Clauss method).
During normal blood coagulation, a coagulation cascade activates the zymogen prothrombin by converting it into the serine protease thrombin. Thrombin then converts the soluble fibrinogen into insoluble fibrin strands. These strands are then cross-linked by factor XIII to form a blood clot. FXIIIa stabilizes fibrin further by incorporation of the fibrinolysis inhibitors alpha-2-antiplasmin and TAFI (thrombin activatable fibrinolysis inhibitor, procarboxypeptidase B), and binding to several adhesive proteins of various cells.Both the activation of Factor XIII by thrombin and plasminogen activator (t-PA) are catalyzed by fibrin.Fibrin specifically binds the activated coagulation factors factor Xa and thrombin and entraps them in the network of fibers, thus functioning as a temporary inhibitor of these enzymes, which stay active and can be released during fibrinolysis.Recent research has shown that fibrin plays a key role in the inflammatory response and development of rheumatoid arthritis.

Information about Tag antibody


FLAG-tag, or FLAG octapeptide, is a polypeptide protein tag that can be added to a protein application recombinant DNA technology. It can be acclimated for affection chromatography, again acclimated to abstracted recombinant, overexpressed protein from wild-type protein bidding by the host organism. It can aswell be acclimated in the abreast of protein complexes with assorted subunits.
A FLAG-tag can be acclimated in abounding altered assays that crave acceptance by an antibody. If there is no antibiotic adjoin the advised protein, abacus a FLAG-tag to this protein allows one to chase the protein with an antibiotic adjoin the FLAG sequence. Examples are cellular localization studies by immunofluorescence or apprehension by SDS PAGE protein electrophoresis.
The peptide arrangement of the FLAG-tag from the N-terminus to the C-terminus is: DYKDDDDK (1012 Da). It can be acclimated in affiliation with added affection tags, for archetype a polyhistidine tag (His-tag), HA-tag or myc-tag. It can be alloyed to the C-terminus or the N-terminus of a protein. Some commercially accessible antibodies (e.g., M1/4E11) admit the epitope alone if it is present at the N-terminus. However, added accessible antibodies (e.g., M2) are position-insensitive.
