| Streptolysin O | Streptolysin O, a group A streptococcal toxin, is a well-characterized oxygen-labile prototype of a cholesterol-binding bacterial exotoxin. Streptolysin O causes both lysis of cells and cardiotoxicity. Streptolysin O is widely used for the controlled permeabilization of cell membranes. Streptolysin O exists in two forms, a reduced active state and an oxidized reversibly inactive state [1] [2] [3] [4]. Uses: Scientific research. Group: Natural products. CAS No. 98072-47-0. Pack Sizes: 25 KU. Product ID: HY-135416. |  |
| Native Human Antistreptolysin O | Streptolysin is a hemolysin produced by group A streptococci. In an infected individual streptolysin O acts as a protein antigen, and the patient mounts an antibody response. A rise in anti-streptolysin O level begins about 1 week after infection and peaks 2-3 weeks later. In the absence of complications or reinfection, the anti-streptolysin O ASO titer will usually fall to preinfection levels within 6-12 months. Both clinical and laboratory findings should be correlated in reaching a diagnosis. Streptococcal infections are caused by bacteria known as Streptococcus. There are several disease-causing strains of streptococci (groups A, B, C, D, and G), which are identified by t... antibody tests are useful for group A streptococci. Group A streptococci are the most virulent species for humans and are the cause of strep throat, tonsillitis, wound and skin infections, blood infections (septicemia), scarlet fever, pneumonia, rheumatic fever, Sydenham's chorea (formerly called St. Vitus' dance), and glomerulonephritis.

| Native Streptococcus pyogenes Streptolysin O | Streptolysin O possesses a single polypeptide chain with a molecular weight of f62 kDa. Streptolysin O binds to membrane cholesterol and oligomerizes to create a ring structure that consists of 45 to 50 units. The ring structure inserts into the membrane to make a large pore (25 to 30 nm), which DNA, RNA, peptides and proteins may pass. It is thiol-activated. It is inhibited by allicin, an active component of garlic. Applications: Permeabilizes membranes to permit cellular uptake of large or charged molecules. streptolysin o is a toxin secreted by streptococcus pyogenes and is a prototype member of poreforming bacterial cytolysins. it is used permeabilize cell membranes to permit cellular uptake of large or charged molecules. it is used to study macromolecule delivery. it is a potential anticancer agent and is used to study suicide cancer gene therapy. Group: Enzymes. Synonyms: Streptolysin O; 98072-47-0; SLO. CAS No. 98072-47-0. SLO. Mole weight: 69 kDa. Storage: 2-8°C. Form: lyophilized powder. Source: Streptococcus pyogenes. Streptolysin O; 98072-47-0; SLO. Cat No: NATE-0671. | |
| Native Streptolysin O from Escherichia coli | Streptolysin O possesses a single polypeptide chain with a molecular weight of f62 kDa. Streptolysin O binds to membrane cholesterol and oligomerizes to create a ring structure that consists of 45 to 50 units. The ring structure inserts into the membrane to make a large pore (25 to 30 nm), which DNA, RNA, peptides and proteins may pass. It is thiol-activated. It is inhibited by allicin, an active component of garlic. Streptolysin-o is one of several toxic immunogenic exoenzymes produced by most strains of group a and many strains of groups c and g, β-hemolytic streptococci. the o in the name stands for oxygenlabile; the other related toxin being oxygen-stable streptolysin-s. the main function of streptolysin o is to cause hemolysis (the breaking open of red blood cells) in particular, beta-hemolysis. Applications: Used in the formulation of anti-streptolysin o (aso) assays which are used in the diagnosis of group a streptococcal based illnesses. Group: Enzymes. Synonyms: Streptolysin O; 98072-47-0; SLO. Enzyme Commission Number: EC.3.2.2.5. CAS No. 9032-65-9. Purity: > 90%. SLO. Appearance: Clear to slightly cloudy solution. Source: Escherichia coli. Streptolysin O; 98072-47-0; SLO. Cat No: NATE-1161. | |
