Northern and Southern Blot Protocols & Introduction
An introduction to both Northern and Southern blotting, popular methods for the transfer of macromolecules to membranous support. This article also offers a Southern blot protocol and a northern blot protocol.
Using Duolink™ in Multiwell Plates
When using the Duolink reagents to stain cells grown in multiwell plates, a few modifications to the Duolink protocol, optimized for staining samples deposited on glass slides, have to be made in order to suit the multiwell format. In particular

Duolink® PLA Multicolor Detection Protocol
Counterstaining after the Duolink In Situ Protocol
We recommend applying the counterstaining protocol after the completion of the Amplification step in section 7.3, step 5 of the Duolink In Situ Fluorescence User Manual.
How to Create PLA® Probes
Duolink® kits use in situ PLA®, a proximity ligation assay technology, to accurately and objectively quantify individual proteins, and their interactions and modifications in unmodified cells and tissue.
Duolink® PLA Probemaker Guide
Guide to create custom PLA probes for immunofluorescent or brightfield detection.
Handling and Storage Protocol for Synthetic Peptides
One of the most challenging aspects of working with synthetic peptides is determining the best solvent in which to dissolve the peptide. General guidelines for proper storage, handling and dissolving your synthetic peptide are provided.
Purification or Removal of DNA-Binding Proteins
This page shows how to purify or remove DNA-binding proteins with Heparin Sepharose High Performance, Heparin Sepharose 6 Fast Flow, Capto Heparin from Cytiva.
Chromatin Isolation by RNA Purification (ChIRP) Protocol
Chromatin Isolation by RNA purification (ChIRP) is a method for isolating regions of the genome that are bound by a specific RNA. This protocol uses magnetic beads coated with streptavidin to isolate the complex.
