General description
- Unsere DNase I schließt Doppelstrang- und Einzelstrang-DNA zu Oligo- und Mononukleotiden auf.
- Rinderpankreas-DNase existiert als vier Isozyme mit folgenden isoelektrischen Punkten für A, B, C und D: 5,22; 4,96; 5,06 und 4,78.3. Die vorherrschende Form ist A, mit kleineren Anteilen von B und C und nur einer geringen Menge von D.
- Die Struktur von DNase I ähnelt der Struktur von Exonuklease III. Sie umfasst zwei zentrale β-Faltblätter. Jedes β-Faltblatt besteht aus sechs β-Strängen. Dieser Komplex aus β-Faltblättern ist von umfangreichen Schleifen und α-Helixregionen umgeben. Dieses Enzym weist eine strukturelle Ähnlichkeit zu Endonuklease III auf.[1]
Application
- Verringert die Viskosität und bietet bessere Ausbeuten, indem DNA bei der Primärzellisolation entfernt wird:
- Integrieren von markierten Basen in DNA: DNA-Nick
- Radioaktive Markierung
- Bioprozesstechnik-Anwendungen: DNA-Entfernung
- Entfernen von genomischer DNA aus RNA-Aufbereitungen vor RT-PCR
- In-vitro-Transkription
- Nick-Translation
- DNase-Footprinting
- Aktinregulierung der Aktinpolymerisation in Zellen und Zellapoptose
- UV-Vernetzung von Proteinen mit Nukleinsäuren
- DNase spielt eine Rolle bei der Regulierung der Aktinpolymerisation in Zellen und ist am Apoptoseprozess beteiligt [1]

I would like to know if this product can be used to eliminate DNA from cells in tissue culture (12 wells chamber slide) before immunofluorescent staining? if it can be used - how?
1 answer-
This product can be used to eliminate DNA from cells in tissue culture. Concentration and incubation time should be optimized based on the specific application.

HOW CAN I PRESERVE DN25 DILUTED and filtered in culture medium? 4C or -20 C?. It will lose activity?
1 answer-
This product is soluble in 0.15 M NaCl at 5 mg/mL. Solutions prepared at 10 mg/mL in 0.15 M NaCl may lose up to 10% activity when stored for 1 week in aliquots at –20 °C. The same solutions stored in aliquots at 2-8 °C can lose up to 20% activity. Please see the link below to review the product datasheet for additional information:

What is the recommended method for long-term storage of the 1 gram bottle of DN25 in solution?
1 answer-
The user bulletin provides guidance on the storage of DNase I once reconstituted. When stored in aliquots at -20°C, solutions of DNase I at 10 mg/mL in 0.15 M NaCl may lose 10% of activity over a week, while storing the same solutions at 2–8°C can result in a 20% activity loss. Alternatively, maintaining solutions at a minimum concentration of 1 mg protein/mL with 5 mM calcium chloride at -20°C can retain 90% activity for at least a year. Solutions with 0.1 mg protein/mL are less stable and may need gelatin as a stabilizer.
For applications not affected by glycerol, two storage buffer options are available as they do not freeze at -20°C:
• 20 mM sodium acetate (pH 6.5) with 5 mM CaCl2, 0.1 mM phenylmethylsulfonyl fluoride (PMSF), and 50% (v/v) glycerol, containing DNase I at 5 mg/mL.
• 10 mM Tris-HCl (pH 7.5) with 50 mM NaCl, 10 mM MgCl2, 1 mM DTT, and 50% (v/v) glycerol, with DNase I at 2 mg/mL.Helpful?

Hi I use the DNase during isolation of cells from lung tissue. Do I need to filter the DNase solution before usage?
1 answer-
This is not a sterile product. If sterility is required due to the specific application, solutions may be filter sterilized before use. Please see the link below to review the product datasheet:

I use the DNase when I isolate lung cells from lung. Do I need to filter them before I use? I will culture the isolated lung cells.
1 answer-
Yes, please filter the DNase solution before use in cell culture, preferably with a 0.22 um filter. The powder is not sterilized as provided.
