Quantifying Corticolous Arthropods Using Sticky Traps

Michael W. Eichholz^*1, Elise C. Zarri^*2, Kevin P. Sierzega^*1

¹Cooperative Wildlife Research Laboratory, Center for Ecology, Department of Zoology, Southern Illinois University, ²Montana Cooperative Research Unit, University of Montana

We describe a semi-quantitative approach of measuring characteristics of corticolous (bark-dwelling) arthropod communities. We placed commercially manufactured sticky traps on tree boles to estimate abundance, total length (a surrogate to biomass), richness, and Shannon diversity for comparison among tree species.

In Situ Detection of Ribonucleoprotein Complex Assembly in the C. elegans Germline using Proximity Ligation Assay

Nicholas J. Day¹, Xiaobo Wang¹, Ekaterina Voronina¹

¹Division of Biological Sciences, University of Montana

This protocol demonstrates use of the proximity ligation assay to probe for protein-protein interactions in situ in the C. elegans germline.

Biochemistry

Resin-Assisted Capture Coupled with Isobaric Tandem Mass Tag Labeling for Multiplexed Quantification of Protein Thiol Oxidation

Matthew J. Gaffrey¹, Nicholas J. Day¹, Xiaolu Li², Wei-Jun Qian¹

¹Integrative Omics, Biological Sciences Division, Pacific Northwest National Laboratory, ²Bioproducts Sciences and Engineering Laboratory, Department of Biological Systems Engineering, Washington State University

Protein thiol oxidation has significant implications under normal physiological and pathophysiological conditions. We describe the details of a quantitative redox proteomics method, which utilizes resin-assisted capture, isobaric labeling, and mass spectrometry, enabling site-specific identification and quantification of reversibly oxidized cysteine residues of proteins.
