Işlenecek kaç örneklerindendir bağlı olarak, bu iki saatlik inkübasyon adımları ve tekrarlanan yıkama ve santrifüj adımları nedeniyle bir süre yoğun bir prosedür olabilir. Bol zaman terk etmek, bu işlem için iki tam gün planlamak için en iyisidir. Artık uygun hacmi kadar (Bölüm Üç tekrarlayın) ek TE yıkar ve santrüfüj yapmaya çalışın, DNA konsantrasyonu ve yıkama sırasında 200-500μl azaltmak için Amicon tüp nihai özü hacmi sorunları vardır.

A correction was made to "<a href="/video/1352">DNA Extraction from 0.22 &#181;M Sterivex Filters and Cesium Chloride Density Gradient Centrifugation</a>". A typo in a volume's measurement was corrected in step 1.2.
The step was corrected from:
Once the filter has thawed, begin the first of two incubations: one to lyse the cells and remove RNA, and one to break down proteins. For the first incubation, add 100 &#956;l lysozyme (125 mg in 1000 &#956;l TE) and 20 ml RNase A (10 &#956;g/ml) to the filter. Reseal the filter with Parafilm and leave it to rotate in the hybridization oven at 37&#176;C for 1 hour.

dna extraction from 0.22 &mu;m sterivex filters and cesium chloride density gradient centrifugation

Bu yöntem, depolama / lizis tamponu ile tedavi edilen ve -80 ° C&#39;de arşivlendi 0.22 mcM Sterivex filtreler üzerinde yoğunlaştı planktonik biyokütleden yüksek molekül ağırlıklı genomik DNA ayıklamak için, ve sezyum klorür yoğunluk gradiyenti kullanarak bu DNA arındırmak için kullanılır. Protokol, hücrelerin DNA kurtarmak ve RNA kaldırmak için iki kez birer saat inkübasyon adımlar ile başlar. Sonra, bir dizi fenol: kloroform ve kloroform ekstraksiyon, proteinler ve hücre zarı bileşenleri, sulu DNA özü toplama, ve özü yıkayın ve konsantre birkaç tampon değişim adımları kaldırmak için santrifüj yoluyla takip yapılır. Beşinci Bölüm, isteğe bağlı arıtma sezyum klorür yoğunluk gradiyenti ile açıklanmıştır. Bu karışıklığı önlemek ve protokol süresini azaltmak için tek seferde en az 15 örnek ile çalışmak tavsiye edilir. Bu protokol için gerekli toplam süre çıkarılan numune sayısı bağlıdır. 10-15 örnekler ve uygun santrifüj ekipmanları mevcut olduğu varsayılarak, tüm bu protokol, 3 gün sürmesi bekleniyor. Hibridizasyon fırınlar sürecin başında ısıya ayarlanmış olduğundan emin olun.
