What is the main goal of the venom extraction protocol?
The main goal is to extract venom for proteomic characterization and gene expression studies.
How is the spider immobilized for venom extraction?
The spider is immobilized using CO2 anesthesia before extraction.
What method is used to collect the venom?
Venom is collected using electrical stimulation and micro capillary tubes.
Why is visual demonstration important in this protocol?
Visual demonstration is critical due to the complexity and coordination required in the venom collection steps.
What analyses can be performed on the collected venom?
Mass spectrometry and other proteomic analyses can be performed on the collected venom.
How are the venom glands prepared for gene expression studies?
Venom glands are dissected two to three days after venom collection for gene expression analysis.
