Insect cell cultures are now commonly used in insect physiology, developmental biology, pathology, and molecular biology. As the field has advanced from methods development to a standard procedure, so has the diversity of scientists using the technique. This paper describes methods that are effective for maintaining various insect cell lines. The procedures are differentiated between loosely or non-attached cell strains, attached cell strains, and strongly adherent cell strains. - [Read Methods for Maintaining Insect Cell Cultures]
Early embryos (0-17 hours or until cuticle formation) are treated with a mixture of organic solvents, formaldehyde, and alcohols, as described here. The cuticles of late-stage embryos are usually opened by sonication. Tissues from more advanced stages of development are normally dissected by hand and then fixed and stained in a standard paraformaldehyde/detergent combination - [Read Preparing Early Whole-Mount Drosophila Embryos for Immunostaining Protocol]
Slide Preparation for Manual Microdissection for Subsequent DNA, RNA, and Protein Analysis. Manual microdissection and subsequent molecular analysis can be carried out on slides stained using standard hematoxylin and eosin methods. However, if cell types that are (or are not) expressing a specific protein are required for a study, then more advanced slide preparation methods such as Immuno-LCM may be utilized. - [Read Slide Preparation for Manual Microdissection Protocol]
