The majority of patients have milder presentations, which include ataxia, myoclonus, angiokeratoma, cognitive and neurologic decline. This can be done by combining 1 l of each 100 M oligo stock in a single tube with an appropriate volume of buffer for a total volume of 500 l. For annealing I use a buffer which has final 10 mM Tris pH 7.4, 1 mM MgCl2, 100 mM NaCl. 2.

If you phosphorylate, then it is easy to check for annealing integrity by ligating the annealed product to itself so that you end up with 160 bp of ligated product versus 80 bp mostly ssDNA. DMSO is commonly used to PCR amplify GC rich sequences, and I wonder if it would be of any help here? -Congenital Disorders of Glycosylation: Screening Algorithm.

I repeated the annealing and it improved a little bit but because the annealing will produce sticky ends that should in theory fit perfectly the sticky ends on the other fragments, I will just use a high amount of this linker and hope that whatever was able to anneal proper will be ligated while all the rest should be excluded from ligation. For convenience, keep Annealing Buffer volume below 500 l for each oligo. I am willing to share my protocol with you if you are interested. Transform 2 l of assembled mix into 50 l of NEB 5-alpha Competent. Use UV back shadowing or a stain such as SYBR Gold to visualize the bands.

Phenotype: infantile onset is characterized by rapidly progressive neurodegeneration, exaggerated startle reflex, "cherry red spot".
