Marker di pesi molecolari

Molecular-weight size markers are a set of standards used to identify the approximate size of a molecule run on a gel during electrophoresis, using the principle that molecular weight is inversely proportional to migration rate through a gel matrix. The molecular weight markers offered are ideal for verification of PCR products, for size analysis of digested DNA, and easy band identification of a number of different fragments. Certain models are available pre-mixed with loading dye.

DNA ladder, 500 bp, DNAmark™

DNA ladder, 500 bp, DNAmark™

Supplier: G-Biosciences

DNAmark™ 500 bp ladder consists of 10 DNA fragments ranging from 500 bp to 5000 bp. The 2000 bp fragment is present at increased intensity to allow easy identification. All fragments are precisely quantified and mixed during the production. For 5 µl loading, all fragments except 2000 bp are 40 ng. The 2000 bp fragment is 100 ng.

DNA QuantLadders

Supplier: LONZA

QuantLadders are prepared from five highly purified DNA fragments that provide visual quantitation of DNA within ±1% accuracy. The DNA QuantLadder provides each DNA fragment in perfect relative mass equivalence at 100 ng, 70 ng, 50 ng, 20 ng and 10 ng. The reverse QuantLadder simply reverses the mass equivalence order of the QuantLadder.

Marker per western blotting, Amersham ECL™ DualVue™

Marker per western blotting, Amersham ECL™ DualVue™

Supplier: Cytiva

I marker per western blotting Amersham ECL™ DualVue™ svolgono due funzioni fondamentali. Anzitutto, le proteine del marker pre-colorato confermano il trasferimento della proteina e definiscono chiaramente l'orientamento del blot. In secondo luogo, le proteine ricombinanti marcate vengono rilevate su pellicola o tramite imaging CCD insieme alle proteine di interesse, consentendo una determinazione del peso molecolare delle proteine target molto accurata. Questi marker vengono rilevati facilmente grazie ad uno specifico coniugato che elimina eventuali contaminazioni incrociate tra le proteine bersaglio e i marker.
