Fig. 1From: BRAF V600 mutations in Langerhans cell histiocytosis with a simple and unique assayOptimization of TspRI digestion for the BRAF amplicons. 100 ng of BRAF PCR fragments amplified from normal DNA were digested with TspRI. Lane 1: No TspRI, 65 °C, 15 min. Lane 2: 5U TspRI, 65 °C, 5 min. Lane 3: 10U TspRI, 65 °C, 10 min. Lane 4: 20U TspRI, 65 °C, 15 min, leading to digestion of the majority of BRAF PCR fragmentsBack to article page
