Ramon Terrado 10.17504/protocols.io.eyzbfx6 Caron Lab - Protistan Ecology This protocol describes how to isolate bacteria in order to label its biomass using 13C-glucose and 15N-ammonia. The first steps aim to isolate candidate bacteria that are able of growing on the chosen substrates for isotopic labeling.The protocol was applied to the isolation of bacetria from freshwater algal cultures, although it can be applied to natural samples.The M9 media used in the protocol is based on the media from Marley, Lu and Bracken (2001).References:Marley, J., Lu, M., & Bracken, C. (2001). A method for efficient isotopic labeling of recombinant proteins. Journal of Biomolecular Nmr, 20(1), 71–75. University of Southern California (USC) 1 2016 Ramon Terrado 2016.

RNA Imaging with MERFISH - Design of Oligonucleotide Probes
 
Resource Report
Resource Website
Jeffrey R. Moffitt, Xiaowei Zhuang 10.17504/protocols.io.menc3de Human Cell Atlas Method Development Community, Neurodegeneration Method Development Community The first step in any MERFISH experiment is the design of the oligonucleotide probes that will be used to label individual RNA species. In our current implementation of MERFISH, each oligonucleotide encoding probe consists of three basic components as illustrated in Figure 2. The first region is a 30-nt targeting region that is complementary to a portion of the sequence of the RNA to which it is designed to bind. The second region is a set of sequences that are called readout sequences, which were designed to be complementary and hence only bind to MERFISH readout probes and not other nucleic acid in the cell. Finally, the third region is a set of priming regions used in the construction of these probes, which will be discussed in detail in Probe Construction. In addition to the nucleotide sequences for each of these components, a codebook —the specific set of binary barcodes that will be used and their association with different RNA species of interest—must also be designed. In this section, we provide protocols to design these sequences and to build a codebook. Example code to perform these steps can be found at http://zhuang.harvard.edu/merfish/ .

Bimanual Interference Experimental Paradigm
 
Resource Report
Resource Website
Rini Varghese, Jasmine Ma, James Gordon, Robert L Sainburg, Carolee J Winstein 10.17504/protocols.io.7r3hm8n Successful bimanual coordination is accomplished by overcoming a variety of cognitive, perceptual and neuromotor constraints, e.g. higher-order representation of task goals, visual perceptual demands, attention demands, task demands (i.e., speed, accuracy) and sensorimotor integration. Sensorimotor interference in planning, executing and correcting bilateral movements especially arise when the hands are required to accomplish two independent or disparate goals. In this study, we describe the experimental paradigm to study sensorimotor interference during performance of a planar reaching task, in which the experimental condition consists of the two hands moving to two visually cued targets at separate distances (spatially asymmetric). Whereas the control conditions consisted of same-size movements performed unimanually with each limb and bimanually to symmetric targets. The paradigm is a modification of a previously conceptualized model task paradigm (e.g. 1-5) to study interference in discrete bilateral movements, wherein the two limbs are tasked with accomplishing asymmetric movement goals. However, our study paradigm involved important modifications to task design such as absence of online visual feedback (so as to test fairly rapid preprogrammed movements) and task instructions which emphasized speed and accuracy but not interlimb synchrony. The study aims: 1) to characterize sensorimotor interference in discrete bilateral reaching movements in young adults, and subsequently, 2) to determine the influence of the side of stroke on such sensorimotor interference. The experimental paradigm was conducted using the KineReach kinematic data collection system and accompanying software (Sainburg, Pennsylvania State University). MATLAB code to generate session and target files for this experiment are included in this protocol. Details of data processing and analysis will be published in the primary papers and code will be made available thereafter.References:1. Kelso (1979)2. Marteniuk (1984)3. Swinnen (1991)4.

This protocal should be paired with our digital PCR protocal. The protocol follows the approximate workflow:Separate and aliquot sample (~4 hrs)Spike with BCoV (~1 hr)Extract RNA (~ 12 hours total, may be split into 2-3 steps/days)Inhibitor removal (~1 hr)Biosafety ConcernsConcentration and extraction procedures that utilize raw samples must adhere to strict Biosafety Level 2+ procedures. These procedures should be performed in a dedicated room. Downstream products may be handled using standard laboratory safety guidelines.
