Objective: Isolation of RNA from serum samples has gained importance, especially in studies on the use of small RNA molecules such as miRNA as biomarkers. Selection of the optimal kit is critical for the accuracy of downstream processing. The aim of this study was to compare the performance of different commercial kits in terms of efficiency, RNA purity and contamination control during the isolation process.
Methods: Three different RNA isolation kits were used for 5 serum samples: 1.miRNeasy Serum/Plasma Kit (Cat. No: 217184, Qiagen, USA), 2.Norgen Plasma/serum RNA purification kit (Cat. No: 55000, Norgen, Canada), 3.Nucleogene RNA isolation kit (Cat. No: NG044, Nucleogene, Turkey). The purity and intensity of the obtained RNAs were evaluated by measuring A260/280 ratios with a nanodrop spectrophotometer.
Results: When the concentrations and A260/280 ratios obtained from the kits were evaluated by One Way Anova Test using GraphPad Prism (V10.4.0), it was observed that there was a statistically significant difference between the concentrations and A260/280 ratios of the 3 kits (p≤0.05 and p≤ 0.001).
RNAs obtained from Norgene had the lowest concentration and the lowest A260/280 ratio, while Nucleogene had the highest RNA concentration and A260/280 ratio of 2 and above among the three kits (p≤0.05).

Amaç: Serum örneklerinden RNA izolasyonu, özellikle miRNA gibi küçük RNA moleküllerinin biyo-belirteç olarak kullanımına yönelik çalışmalarda önem kazanmıştır. Optimal kitin seçimi sonraki işlemlerin doğruluğu için kritik öneme sahiptir. Bu çalışmanın amacı izolasyon sürecinde farklı ticari kitlerin verimlilik, RNA saflığı ve kontaminasyon kontrolü açısından performanslarını kıyaslamaktır.
Yöntem: Çalışmada 5 serum örneği için üç farklı RNA izolasyon kiti kullanılmıştır: 1. miRNeasy Serum/Plazma Kiti (Kat. No: 217184, Qiagen, ABD), 2. Norgen Plazma/serum RNA saflaştırma kiti (Kat. No: 55000, Norgen, Kanada), 3. Nucleogene RNA izolasyon kiti (Kat. No: NG044, Nucleogene, Türkiye). Elde edilen RNA’ların saflık ve yoğunluğu nanodrop spektrofotometre ile A260/280 oranları ölçülerek değerlendirilmiştir.
Bulgular: Kitlerden elde edilen konsantrasyonlar ve A260/280 oranları GraphPad Prism (V10.4.0) kullanılarak One Way Anova Testi ile değerlendirildiğinde, 3 kitin konsantrasyonları ve A260/280 oranları arasında istatistiksel olarak anlamlı bir fark olduğu görülmüştür (p≤0,05 ve p≤ 0,001).
Norgene'den elde edilen RNA'lar en düşük konsantrasyona ve en düşük A260/280 oranına sahipken, Nucleogene üç kit arasında en yüksek RNA konsantrasyonuna ve 2 ve üzeri A260/280 oranına sahipti (p≤0,05).
Sonuç: Serum RNA izolasyonu için kullanılan kitler arasında Nucleogene kiti genel olarak en yüksek RNA verimi ve uygun A260/280 değerleriyle öne çıkmaktadır. Bununla birlikte Qiagene ve Norgene kitleri bazı spesifik durumlarda tercih edilebilir.
