This is a protocol to isolate active full length Kinesin from Drosophila embryos for single-molecule biophysical studies. We show how to collect embryos, make the embryo lysate, and then polymerize microtubules (MTs). Kinesin is purified by immobilizing it on the MTs, spinning down the Kinesin-MT complexes, and then releasing the kinesin from the MTs via ATP addition.

Slice cultures facilitate the manipulation of embryo development by gene and pharmacological perturbations. However, culture conditions must ensure that normal development can proceed within the reduced environment of the slice. We illustrate a protocol that facilitates normal spinal cord development to proceed for at least 24 hr.

2013
We report an efficient and simple method to isolate embryos at early stages of development from Arabidopsis thaliana seeds. Up to 40 embryos can be isolated in 1 hr to 4 hr, depending on the downstream application. The procedure is suitable for transcriptome, DNA methylation, reporter gene expression, immunostaining and fluorescence in situ hybridization analyses.
FAQs
Careful dissection preserves the embryo’s structure while removing extraembryonic and uterine tissues that could interfere with later analysis. Excessive mechanical force can damage the specimen, whereas incomplete tissue removal may reduce the consistency of samples used for imaging, molecular analysis, or neural culture preparation. The balance between tissue clearance and physical protection therefore directly influences sample quality.
Aseptic handling minimizes contamination introduced during recovery and tissue removal. This is especially important when isolated embryos provide material for primary neural cultures, because contamination can compromise the sample and reduce the reliability of downstream observations. Maintaining clean handling conditions supports viable material for developmental studies and helps make results more reproducible across experiments.
Structural preservation and viability are central because they determine whether an isolated embryo remains suitable for later investigation. Intact material can support examination of neural development, preparation of primary neural cultures, and analysis of genetic or environmental influences on nervous-system formation. Consistent sample condition also improves the interpretability of imaging and molecular results.
The workflow centers on recovering the embryo, carefully dissecting it from maternal or surrounding tissues, removing extraembryonic and uterine components, and maintaining aseptic conditions throughout handling. Each stage has a distinct purpose: recovery obtains the specimen, dissection and tissue removal improve its suitability for study, and clean handling helps protect viability and limit contamination.
Isolated embryos are useful when investigators need material to examine neural development or prepare primary neural cultures. They also support studies of how genetic or environmental factors influence nervous-system formation. Because the recovered material can be directed toward developmental investigations, imaging, or molecular analysis, the protocol connects specimen preparation with several complementary neuroscience research approaches.
Consistent isolation produces samples with more comparable structural condition and viability, which strengthens downstream comparisons. Researchers can use such material for imaging, molecular analysis, developmental investigations, and neural culture preparation. In neuroscience, this consistency helps distinguish effects associated with genetic or environmental factors from variation introduced during specimen recovery and handling.
