Reusing Nylon Membranes for Radioactive Hybridizations

Reusing nylon membranes for radioactive hybridizations.

We describe a procedure for recycling nylon hybridization membranes, enabling their repeated use for radioactive Southern hybridization analysis of different DNA samples. Following hybridization and probe removal, nylon membranes containing covalently linked DNAs were treated with 0.55% sodium hypochlorite. This destroyed the DNA, thereby preventing it from participating in further hybridizatio...

A common reference for cDNA microarray hybridizations.

Comparisons of expression levels across different cDNA microarray experiments are easier when a common reference is co-hybridized to every microarray. Often this reference consists of one experimental control sample, a pool of cell lines or a mix of all samples to be analyzed. We have developed an alternative common reference consisting of a mix of the products that are spotted on the array. Po...

Reverse-Bumpy-Ball-Type-Nanoreactor-Loaded Nylon Membranes as Peroxidase-Mimic Membrane Reactors for a Colorimetric Assay for H2O2

Herein we report for the first time fabrication of reverse bumpy ball (RBB)-type-nanoreactor-based flexible peroxidase-mimic membrane reactors (MRs). The RBB-type nanoreactors with gold nanoparticles embedded in the inner walls of carbon shells were loaded on nylon membranes through a facile filtration approach. The as-prepared flexible catalytic membrane was studied as a peroxidase-mimic MR. I...
