Bead aggregation assay to demonstrate presynaptic differentiation induced by the NGL family of cell adhesion molecules. - [Read Bead Aggregation Assay Protocol]
A silver stain to demonstrate neurofibrillary tangles, nerve fibers and senile plaques in Alzheimer's disease. The nerve fibers are sensitized with a silver solution. The sections are treated with ammoniacal silver, and then reduced to a visible metallic silver. - [Read Bielschowsky Technique for Senile Plaques Protocol]
Protocol to demonstrate amyloid deposits in tissue sections. When stained with the Congo Red Stain the amyloid, with the aide of polarizing lenses, will birefringe an apple green color. Under the microscope. - [Read Congo Red Putcher's Modification Amyloid Protocol]
High-resolution SNP mapping by denaturing HPLC. A SNP mapping procedure that relies on resolving polymorphisms by denaturing HPLC without the necessity of determining the nature of the SNPs. They demonstrate the use of denaturing high-performance liquid chromatography to identify mutations in the candidate genes and to fine-map chromosomal breakpoints. - [Read High-resolution SNP mapping by denaturing HPLC]
This procedure was first described by Bertrand et al to demonstrate that ribozymes could be enzymatically active in vivo. We adapted the method to show that certain oligodeoxynucleotides could direct the activity of endogenous ribonuclease H to cleave tar - [Read Reverse Ligation Mediated RT - PCR]
