RNAi In Situ

Sigma® has prepared product lists for commonly used protocols from Cold Spring Harbor Protocols.

Thomas Lufkin
This protocol was adapted from "Techniques for Visualizing Gene Products, Cells, Tissues, and Organ Systems," Chapter 16, in Manipulating the Mouse Embryo, 3rd edition, by Andras Nagy, Marina Gertsenstein, Kristina Vintersten, and Richard Behringer. Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY, USA, 2003.

This is a protocol describing how to perform in situ hybridization on whole mouse embryos. Here we describe the hybridization procedure, and the localization of the DIG-labeled RNA using a conjugate of anti-DIG Fab antibody and calf intestinal alkaline phosphatase. Enzyme activity of the reporter is detected by a color reaction, resulting in the formation of a water-insoluble purple/blue precipitate.
