Cot-1 Humane DNA

Cot I DNA für: Mikroarray Anwendungen, komparative genomische Hybridisierung (CGH), Karyotyping , In-Situ Hybridisierung

Beschreibung:
Die Cot I Humane DNA wird ausschließlich aus Plazenten von Frauen gewonnen, die ein männliches, neugeborenes Kind ausgetragen haben. Spezielle, aufwendige Aufreinigungsverfahren reichern die DNA mit repetitiven Elementen an. Cot I Humane DNA Fraktion von GeneON enthält mindestens 98 % dieser repetitiven und schnell anlagernden Elemente.

Anwendungen:
Unterdrückung von Kreuzhybrisierungen menschlicher repetitiver DNA bei:
– Filter- oder Mikroarray Hybridisierungen
– In-situ-Hybridisierungen
Single-Copy“-Gen Hybridisierungen

Konzentration: > 1,1 mg / ml, in 10 mM Tris-HCl, 1 mM EDTA, pH 7.4

Qualitätskontrolle:
Durchschnittliche Fragmentgröße: 50-300 bp
A260/A280: 1.78
Enthaltene genomische DNA (non-repetitive DNA): < 2%.
Alle Chargen sind garantiert getestet auf und frei von HIV1,2 RNA, HCV RNA und HBV DNA

Transport: mit Kühlakkus

Lagerung: bei – 20°C für mindestens 12 Monate

Recommendation from a researcher:

For Southern blot hybridizations: add 50 μg of COT-1 human DNA (@ 10 μg/μL) to 50 μL of 20X SSC, 25 μL distilled water and 20 μL of a solution containing 0.1 M NaCl, 0.1 M Tris-HCl (pH 7.4). 0.01 M EDTA, and 1% SDS to the probe for each 25 to 500 ng of probe.

For in situ hybridizations: combine genomic probe with the proper amount of COT-1 human DNA such that the final concentration of COT-1 human DNA is 0.3 μg/μL for cosmid, plasmid, and lambda probes; or, at 1 μg/μL for Alu PCR probes.
Ethanol precipitate and resuspend in a half-volume of 100% formamide. Add a half-volume of 20% dextran sulfate in 2X SSC (prewarmed to 75 degrees C) and mix well. Denature mix by heating to 75 °C for 5 min. Incubate at 37 °C for at least 5 and up to 15 min.

Product usage: Superscript II RT was used to make labeled cDNA from a human polyA RNA sample (42C incubation temp). Cy3 or Cy5 labeled dCTP was used for these experiments. Remaining RNA was degraded by using a combination of RNase H (Invitrogen) and RNase A (USB). Array hybridization was per……

Product usage: Cultures of the human squamous cell carcinoma line SCC12(c12c2) were plated at 2.5 × 106 to 5 × 106 cells/60-mm dish and grown to 70-90% confluence before transfection. The transient transfection was performed by a lipofection method in a serum-free medium with 2.5 µg of each pla……
