Alsever's solution is a saline liquid used to prevent coagulation of blood. It is composed of 2.05% dextrose, 0.8% sodium citrate, 0.055% citric acid, and 0.42% sodium chloride. For usage, an equal volume of blood is gently, but thoroughly, mixed with the solution. This solution is used to study "in vitro" anti-inflamm... | https://en.wikipedia.org/wiki?curid=42563388 |

Plasmid partition system A plasmid partition system is a mechanism that ensures the stable inheritance of plasmids during bacterial cell division. Each plasmid has its independent replication system which controls the number of copies of the plasmid in a cell. The higher the copy number is, the more likely the two daug... | https://en.wikipedia.org/wiki?curid=42574504 |
Plasmid partition system This complex recruits the motor protein, which is a nucleotide triphosphatase (NTPase). The NTPase uses energy from NTP binding and hydrolysis to directly or indirectly move and attach plasmids to specific host location (e.g. opposite bacterial cell poles). The partition systems are divided in ... | https://en.wikipedia.org/wiki?curid=42574504 |
Plasmid partition system The amino-acid sequence identity can go down to 15% between ParM and other actin-like ATPase. The mechanism of partition involved here is a pushing mechanism: The filament of ParM is regulated by the polymerization allowed by the presence the partition complex (ParR-"parC"), and by the depolyme... | https://en.wikipedia.org/wiki?curid=42574504 |
Plasmid partition system This gene does not effect the plasmid copy number nor the grow rate (excluding its implication in a post-segregational killing system). A centromere-like binding sequence is present upstream of the "par" gene, and is composed of seven direct repeats and one inverted repeat. | https://en.wikipedia.org/wiki?curid=42574504 |
Intercalation (biochemistry) In biochemistry, intercalation is the insertion of molecules between the planar bases of deoxyribonucleic acid (DNA). This process is used as a method for analyzing DNA and it is also the basis of certain kinds of poisoning. There are several ways molecules (in this case, also known as "lig... | https://en.wikipedia.org/wiki?curid=42600851 |
Intercalation (biochemistry) In order for an intercalator to fit between base pairs, the DNA must dynamically open a space between its base pairs by unwinding. The degree of unwinding varies depending on the intercalator; for example, ethidium cation (the ionic form of ethidium bromide found in aqueous solution) unwind... | https://en.wikipedia.org/wiki?curid=42600851 |
Intercalation (biochemistry) The ligand displaces a sodium and/or magnesium cation present in the "condensation cloud" of such cations that surrounds DNA (to partially balance the sum of the negative charges carried by each phosphate oxygen), thus forming a weak electrostatic association with the outer surface of DNA. ... | https://en.wikipedia.org/wiki?curid=42600851 |
