Molecular and Biochemical Analysis of Arabidopsis Protocol - http://www.roche-applied-science.com/PROD_INF/MANUALS/InSitu/pdf/ISH_197-207.pdf

Category: Plant Biology Protocols

The standard protocol for in situ hybridizations in plants still involves fixing fresh tissue, embedding the tissue in wax, sectioning with a microtome and detection of the transcripts of interest using labeled RNA-probes. This protocol concentrates only on nonradioactive methods, as they are easy to perform, very sensitive and even faster than techniques involving radioisotope labels. - [Read Molecular and Biochemical Analysis of Arabidopsis Protocol]

Category: Immunohistochemistry Protocols: Antibody Staining Protocols

Frozen tissue sections show good preservation of tissue structure and antigens. The principle disadvantages of using them in immunostaining are that the specimens must be stored frozen, and a special microtome, known as a cryostat, is required. Also, many clinical specimens are not available in this form, and most classic histological descriptions of tissue structure and pathology are based on the use of paraffin-embedded sections of formalin-fixed material. - [Read Preparing Frozen Tissue Sections for Immunostaining Protocol]

Paraffin Embedding Protocol

Paraffin Embedding Protocol for molecular profiling. This Paraffin Embedding Protocol describes the processing of the tissues into sections following ethanol fixation. Molecular profiling (MP) is a technique that is used to visualize the global patterns of RNA expression or protein expression in various cell types and disease processes.
