Lyme disease research studies often require generation of ticks infected with the pathogen Borrelia burgdorferi, a process that typically takes several weeks. Here we demonstrate a microinjection-based tick infection procedure that can be accomplished within hours. We also demonstrate an immunofluorescence method for in situ localization of B. burgdorferi within ticks.
Simultaneous, Rapid, and Highly Efficient Protein Transfer Using the Trans-Blot Turbo Transfer System - ADVERTISEMENT
The Trans-Blot Turbo system reduces protein transfer protocols from gels to as little as 3 minutes, while maintaining high efficiency transfers and high throughput. The system enables protein transfer of 2 mini gels in 3 minutes and up to 4 mini gels in as little as 7 minutes.
Extraction of Venom and Venom Gland Microdissections from Spiders for Proteomic and Transcriptomic Analyses
1Department of Biological Sciences, University of Massachusetts Lowell
This article provides a protocol for the extraction of venom from spiders using electrical stimulation in order to 1) conduct proteomic characterization, 2) stimulate venom gland gene expression, and 3) perform functional studies of venoms. This is followed by a description of venom gland microdissections for gene expression studies.

Lyme disease is the most commonly-reported vector-borne disease in North America. The causative agent, Borrelia burgdorferi is a spirochete bacterium transmitted by Ixodid ticks. Transmission and detection of infection in animal models is optimized by the use of tick feeding, which we describe here.

The collection of infected tick hemolymph, salivary glands, and saliva is important to study how tick-borne pathogens cause disease. In this protocol we demonstrate how to collect hemolymph and salivary glands from feeding Ixodes scapularis nymphs. We also demonstrate saliva collection from female I. scapularis adults.

The technique presented here measures the path of freely swimming microscopic species using single wavelength exposure. C. elegans are used to demonstrate shadow imaging as an inexpensive alternative to costly microscopes. This technique can be adapted to accommodate various orientations, environments and species to measure direction, speed, acceleration and forces.
