WebCloning single gRNA plasmids To introduce target sites into the single gRNA vectors pCFD1-3 we are using a cloning strategy that ligates two annealed oligos into the backbone that has been digested with a type II-S restriction enzyme. Use different concentration of the annealed oligos in the ligation mix. I have tried mixing them in 1x Annealing Buffer (10 mM Tris, pH 7.58.0, 50 mM NaCl, 1 mM EDTA) at 10uM final concentration for both the forward and the reverse and then putting them at 97C for 10-15 min and cooling down slowly either on a thermomixer or on a thermal cycler with a decrease of 1 degree/minute after the 97C step. Not for use in diagnostic procedures. Transformation/plating/picking colonies 2ul ligation reaction mix is added to 25ul competent cells (DH5). This is a screening test; not all oligosaccharidoses are detected. Take advantage of free shipping for any order totaling over $350. To obtain a long double stranded DNA with sticky ends, I started from multiple oligos (see attached file) instead of only 2 long oligos in order to avoid having internal annealing and secondary structure. You can arrange these structures in order of decreasing melting temperature (Tm). Not for use in diagnostic procedures. *Note: you can also use TE buffer (10 mM Tris, 0.1 mM EDTA; pH 8.0) supplemented with 50 mM NaCl as an annealing buffer. 0000000016 00000 n Clinical diagnosis can be difficult due to the similarity of clinical features across disorders and their variable severity.
