Immunohistochemistry (the localization of proteins in a tissue by binding antibodies to specific antigens) is a technique where one protocol definitely does not fit all. Each model organism seems to have its own quirks, whether it be in the fixative used, the methods needed for antibody penetration, issues with autofluorescence or even just figuring out which cross-species antibodies work in a given system. To that end, we’ve been working on expanding our coverage of immunohistological protocols. The February issue of CSH Protocols brings methods for plant sections, using both avidin-biotin and alk-phos, as well as a method for whole-mount immunocytochemistry in Xenopus embryos from John Wallingford’s lab at the University of Texas (they provided the lovely cover image for this month).

September’s issue of CSH Protocols is upon us (my, that was a quick summer–Kurt Weill sure knew what he was talking about). We’re featuring two protocols this month, both available freely to non-subscribers (as are all of our sample protocols). The first is for generating mouse models for squamous cell carcinoma and the second is for the Oligonucleotide Ligation Assay (OLA), used for finding Single-Nucleotide Polymorphisms (SNP’s).
