Detecting Spaciotemporal Transcript Accumulation in Maize by RNA In Situ Hybridization

Authors: Josh Strable and James W. Satterlee, date: 02/20/2021, view: 248, Q&A: 0

RNA in situ hybridization is a method for visualizing spatiotemporal transcript accumulation in cells and tissues. The method provides clear resolution, is highly sensitive and specific, and can uncover gradients of transcript accumulation ...

Transcardiac Perfusion of the Mouse for Brain Tissue Dissection and Fixation

Authors: Jinyun Wu, Yuqi Cai, Xiaoyang Wu, Yue Ying, Yilin Tai and Miao He, date: 01/05/2021, view: 976, Q&A: 0

Transcardiac perfusion with saline followed by 4% paraformaldehyde (PFA) is widely used to clear blood and preserve brain for immunostaining or in situ hybridization. PFA breaks into formaldehyde in solution, which cross-link protein and ...

In vitro assessment of ivermectin resistance and gene expression profiles of P-glycoprotein genes from Haemonchus contortus (L₃)

Authors: Marilyn Cedillo-Borda, Ma. Eugenia López-Arellano and David E. Reyes-Guerrero, date: 12/20/2020, view: 399, Q&A: 0

The aim of the present protocol is to improve the methodology to identify resistance to ivermectin (IVM), one of the main anthelmintic drugs against parasitic nematodes of ruminants, using the blood-feeding nematode Haemonchus contortus as ...

Immunophenotyping and Intracellular Staining of Fixed Whole Blood for Mass Cytometry (CyTOF)

Authors: Sangeeta Kowli and Holden Maecker, date: 09/05/2020, view: 2104, Q&A: 0

In this report, we present the implementation of mass cytometry for intracellular staining using fixed whole blood. In our assay described here, 250 µl of whole blood, is stimulated in vitro with PMA/ionomycin (or left unstimulated), in the ...

A Detailed and Radioisotope-free Protocol for Electrophoretic Mobility Shift Assay (EMSA)

Author: Nguyen Hoai Nguyen, date: 08/20/2020, view: 1067, Q&A: 0

To comprehensively characterize the functions of a transcription factor (TF), it is required to analyze the interaction of this TF with its targeted loci. Several methods such as β-glucuronidase (GUS) or luciferase reporter, yeast one-hybrid (Y1H), ...

Heterologous Expression and Purification of SARS-CoV2 Nucleocapsid Protein

Authors: Ankur Garg, Lihong Liu, David D. Ho and Leemor Joshua-Tor, date: 08/05/2020, view: 2264, Q&A: 0

This protocol describes a step by step method for heterologous expression of SARS-CoV2 Nucleocapsid (N) protein in Escherichia coli. Moreover, this protocol includes steps to purify the N protein to high purity and homogeneity. Thus, ...
