When added to the DNA library in solution, the probes hybridise with their targets. The targeted DNA fragments bound to the probes are captured using magnetic beads coupled with streptavidin, which has a high affinity for the biotin present on the probes. Non-targeted DNA is removed through successive washes, whilst the probe-target sequence complex is retained by magnetisation. A short PCR amplification step increases the quantity of sequences and degrades the probes. Sequencing can be performed independently on an Illumina MiSeq i100 or NextSeq 2000 (depending on the number of targets and\/or samples).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img data-recalc-dims=\"1\" fetchpriority=\"high\" decoding=\"async\" width=\"750\" height=\"321\" data-attachment-id=\"554\" data-permalink=\"https:\/\/pgtb.fr\/en\/nimblegene\/\" data-orig-file=\"https:\/\/i0.wp.com\/pgtb.fr\/wp-content\/uploads\/2022\/02\/nimblegene.png?fit=1001%2C429&amp;ssl=1\" data-orig-size=\"1001,429\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"nimblegene\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/pgtb.fr\/wp-content\/uploads\/2022\/02\/nimblegene.png?fit=750%2C321&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/pgtb.fr\/wp-content\/uploads\/2022\/02\/nimblegene.png?resize=750%2C321&#038;ssl=1\" alt=\"\" class=\"wp-image-554\" style=\"width:780px;height:334px\"\/><\/figure>\n\n\n\n<h2 id=\"avantages\" class=\"wp-block-heading\">Benefits<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Capture of panels of varying sizes (up to 24 MB)<\/li>\n\n\n\n<li>Tolerance to polymorphisms: a probe panel can be used on closely related species<\/li>\n\n\n\n<li>Advanced technology for the extraction of ancient or degraded DNA<\/li>\n\n\n\n<li>It is possible to focus on specific areas of interest by increasing the density of the sensors (tilling)<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"inconvenients\" class=\"wp-block-heading\">Disadvantages<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Requires high-quality DNA<\/li>\n\n\n\n<li>Probe non-specificity can lead to hybridisation at other regions of the genome (off-target)<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" style=\"font-size:29px\">Services<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">SureSelect capture of DNA and methylated DNA, on panels ranging from 0.5 Mb to 24 Mb, for a few samples up to several hundred.
