Gentamycin (Gentamicin) Sulfate USP Quick inquiry Where to buy Suppliers range | Broad spectrum, cell culture aminoglycoside antibiotic that is non toxic to viruses and mammalian cells at antibacterial levels. Inhibits growth of gram positive and negative bacteria, and mycoplasma. Inhibits normal protein synthesis by binding to L6 protein of 50S ribosomal subunit. Useful antibiotic for Baculovirus expression systems since mutations in rplF prevent Gentamycin from binding.Causes codon misreading by binding to the 30S ribosomal subunit, blocking the translocation of peptidyl-tRNA from the acceptor site to the donor site. Antibacterial against Gram-negative aerobic bacteria, Gram-positive bacteria and mycoplasmas. Used as a selection agent (gentamicin-resistance gene) in molecular biology applications. Broad-spectrum cell culture antibiotic that is nontoxic to viruses and mammalian cells at antibacterial and antimycoplasmal concentrations. Due to its extended stability and slow development of bacterial resistance, it is a useful antibiotic in long-term virus und tissue culture studies.Bactericidal effects are exerted by the binding to the outer membrane, causing disruption of the membrane. This increases the permeability of the cell envelope, leakage of cell contents, and leading to apoptosis and proteolysis (cell death). Causes also cell death by generation of free radicals, phospholipidosis, extracellular calcium-sensing recep- tor stimulation and energetic catastrophe. Source:Micromonospora sp. Group: Biochemicals.

Lead Quick inquiry Where to buy Suppliers range | Lead. Uses: The metal is not attacked by hot water. But in the presence of free oxygen, lead(II) hydroxide is formed. The overall reaction is: 2Pb + 2H2O + O2 ? 2Pb(OH)2 In hard water, however, the presence of small amounts of carbonate, sulfate, or silicate ions form a protective film on the metal surface, and prevent the occurrence of the above reaction and thus, corrosion of the metal. Lead does not evolve hydrogen readily with acids. Nitric acid attacks the metal readily, forming lead nitrate and oxides of nitrogen: 3Pb + 8HNO3 ? 3Pb(NO3)2 + 2NO + 4H2O This reaction is faster in dilute nitric acid than strong acid. Hydrochloric acid has little effect on the metal. At ordinary temperatures, lead dissolves slowly in hydrochloric acid, forming a coating of lead(II) chloride, PbCl2 over the metal, which prevents further attack. At ordinary temperatures, lead is not readily attacked by sulfuric acid. A coating of insoluble lead sulfate formed on the metal surface prevents any further reaction of the metal with the acid. The acid is, therefore, stored in specially designed lead containers. Also, the action of hot concentrated sulfuric acid is very low up to about 200°C. However, at temperatures near 260°C, both the concentrated sulfuric and hydrochloric acids dissolve lead completely. At ordinary temperatures, hydrofluoric acid also has little action on the metal. Formation of insoluble PbF2 prevents dissolution of lead in the acid. Organic acids in the presence of oxygen react slowly with lead, forming their soluble salts. Thus, acetic acid in the presence of oxygen forms lead(II) acetate: 2Pb + 4CH3COOH + O2 ? 2Pb(CH3COO)2 + 2H2O Lead dissolves in alkalies forming plumbite ion, Pb(OH)42¯ with the evolution of hydrogen: Pb + 2OH¯ + 2H2O ? Pb(OH)42¯ + H2 Lead combines with fluorine, chlorine, and bromine, forming bivalent lead halides: Pb + Cl2 ? PbCl2 Fusion with sulfur at elevated temperatures yields lead sulfide, PbS. The metal is oxidized to PbO when heated with sodium nitrate at elevated temperatures. Pb + NaNO3 ? PbO + NaNO2 Lead is widely used in storage batteries. Each cell consists of a spongy lead plate as cathode and lead dioxide as anode immersed in the electrolyte sulfuric acid. The overall chemical reaction in the cell during discharge is as follow | |

Quinidine Quick inquiry Where to buy Suppliers range | Quinidine. Uses: Quinidine occurs in cinchona bark to about0.25-0.3% and also in cuprea bark. It is present in quinine sulfate mother liquor. Itis formed by isomerization of quinine. Itis used in the prevention of certain cardiacarrhythmias.Primary indications for the use of quinidine include (1) abolition of premature complexes that have an atrial, A-V junctional, or ventricular origin; (2) restoration of normal sinus rhythm in atrial flutter and atrial fibrillation after controlling the ventricular rate with digitalis; (3) maintenance of normal sinus rhythm after electrical conversion of atrial arrhythmias; (4) prophylaxis against arrhythmias associated with electrical countershock; (5) termination of ventricular tachycardia; and (6) suppression of repetitive tachycardia associated with Wolff- Parkinson-White (WPW) syndrome. Although quinidine often is successful in producing normal sinus rhythm, its administration in the presence of a rapid atrial rate (flutter and possibly atrial fibrillation) can lead to a further and dangerous increase in the ventricular rate secondary to inhibition of basal vagal tone upon the A-V node. For this reason, digitalis should be used before quinidine when one is attempting to convert atrial flutter or atrial fibrillation to normal sinus rhythm. Group: Heterocyclic Organic Compound.
