Many of the Swift products you have grown to love are now part of our new complete portfolio, xGen NGS. You can proceed to cloning since only productive annealing will ligate. %%EOF When abnormal results are detected with characteristic patterns, a detailed interpretation is given, including an overview of results and significance, a correlation to available clinical information, elements of differential diagnosis, recommendations for additional confirmatory studies (enzyme assay, molecular genetic analysis). startxref WebUse 3 annealing reactions: 1) oligo sense only 2) oligo antisense only 3) oligo sense + antisense Run a bit of each sample on a 2% agarose gel with ethidium bromide. Clinical features can include bone abnormalities, coarse facial features, corneal cloudiness, organomegaly, muscle weakness, hypotonia, developmental delay, and ataxia. 0000019240 00000 n Use different concentration of the annealed oligos in the ligation mix. So far when I run the single strand DNA (either forward or reverse sequence) and the "annealed" mixture in a 1% agarose gel the "annealed" sample is migrating more (lower) and produces a smear (possible DNA degradation?). Phenotype: continuum of clinical features ranging from severe and rapidly progressive disease to a milder and more slowly progressive course; infantile onset (type I) is characterized by rapidly progressive neurodegeneration. Without seeing your sequence I can still assume such long DNA strands will likely pair up randomly as well as having various forms of self-hairpins.
