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 ladder 250 to 10000 bp, AMPIGENE®
Supplier: Enzo Life Sciences
AMPIGENE® DNA ladder contains DNA fragments ranging from 250 to 10000 bp that can be used as molecular weight standards for agarose gel electrophoresis. The bands are evenly spaced and are intensified at 1000 bp and 3000 bp to serve as easily identifiable reference bands. The approximate mass of DNA in each of the bands is provided, assuming 5 µl load, for determining the approximate mass of DNA in samples with comparable intensity and sizes.
