Hi, as Sathya Srinivasan says CTCF is basically background subtraction, so if there's a significant background in your images and the background level can vary from image to image (especially between sample and control), it will help you to get background-independent fluorescence readings. WebT-ALL is characterized by specific driving oncogene rearrangements that delineate 4 to 5 subtypes that harbor unique expression signatures. 63, 69, 70, 71 CTCF aberrations were especially frequent in patients with T-ALL with TLX3-rearrangements (53%) compared with patients with other driving oncogenic rearrangements (6%, p = 2.2 × 10 −16; Figure 1 E). brabantia 60 metre washing line
