Ihre Suche nach: Molekulargewichtsmarker
Molekulargewichts-Referenzmarker sind Standardsätze, die verwendet werden, um die ungefähre Größe eines Moleküls bei der Elektrophorese zu identifizieren. Dies beruht auf dem Prinzip, dass das Molekulargewicht umgekehrt proportional zur Wanderungsgeschwindigkeit durch eine Gittermatrix ist. Die angebotenen Molekulargewichtsmarker sind ideal zur Verifizierung von PCR-Produkten, zur Größenanalyse von verdauter DNA und zur einfachen Banderkennung verschiedener Fragmente. Bestimmte Modelle sind bereits mit Ladepuffer vorgemischt erhältlich.
Lambda DNA phage, E. coli W8850
Supplier: Rockland Immunochemicals
Lambda phage consists of a virus particle including a head (also known as a capsid), a tail and tail fibres. The head contains the phage's double-stranded circular DNA genome. The phage particle recognises and binds to its host E.coli causing DNA in the head of the phage to be ejected through the tail into the cytoplasm of the bacterial cell. Lambda phage DNA is commonly used as a DNA molecular weight marker. Digestion of the lambda phage genome with HindIII produces a set of 8 fragments consisting of 125, 560, 2000, 2300, 4300, 9400, and 23000 base pairs.

DNA ladders, ultra low range, FastRuler
Supplier: Thermo Fisher Scientific
FastRuler ultra low range DNA ladder is specifically designed for fast sizing and approximate quantification of double-stranded DNA in 48 well (or 96-well) high throughput gels, as well as in conventional agarose gels. The ladder is a mixture of five blunt-ended chromatography-purified individual DNA fragments that are easily resolved in a short separation distance (10 to 20 mm) after an 8 to 14 minutes run on the appropriate agarose gel.

DNA ladder, O'RangeRuler™
Supplier: Thermo Fisher Scientific
O'RangeRuler™ DNA ladders are step ladders that consist of basic unit repeats of 10, 15, 20, 50, 100, 200, or 500 bp. The ladders have a higher density of bands at a specific DNA size range and are therefore suitable for more accurate sizing of DNA in agarose or non denaturing polyacrylamide gels.
