[Abstract] Although many spherical and rod-shaped plant virus purification protocols are now available, only a few protocols on filamentous plant virus purification have been published. Here, we report a protocol for large-scale purification of Rice stripe virus (RSV) from RSV-infected rice tissues. RSV virions with high infectivity were first precipitated ...
Yeast Single-cell RNA-seq, Cell by Cell and Step by Step
[Abstract] Single-cell RNA-seq (scRNA-seq) has become an established method for uncovering the intrinsic complexity within populations. Even within seemingly homogenous populations of isogenic yeast cells, there is a high degree of heterogeneity that originates from a compact and pervasively transcribed genome. Research with microorganisms such as yeast ...
Detachment Procedure of Bacteria from Atmospheric Particles for Flow-cytometry Counting
[Abstract] The protocol separates bacteria from atmospheric particles, obtaining with greater precision their abundance in the atmospheric deposition. This procedure is similar to the one used to separate bacteria in streambed sediments. The detachment procedure consists of a chemical treatment with sodium pyrophosphate and Tween 20 and a physical treatment ...

[Abstract] Continuous in vitro growth of Cryptosporidium parvum has proved difficult and conventional in vitro culture techniques result in short-term (2-5 days) growth of the parasite resulting in thin-walled oocysts that fail to propagate using in vitro cultures, and do not produce an active infection using ...
Alphavirus Purification Using Low-speed Spin Centrifugation
[Abstract] Chemical and sedimentation procedures are used to purify virus particles. While these approaches are successful for wild-type viruses, they are often not feasible for purifying mutant viruses with assembly defects. We combined two published methods (Atasheva et al., 2013; Moller-Tank et al., 2013), to generate a protocol that ...
Induction, Isolation and Counting of Akinetes in Aphanizomenon ovalisporum
[Abstract] Akinetes are spore-like resting (dormant) cells formed by strains of filamentous cyanobacteria for surviving long periods of unfavorable conditions. During deprivation for potassium, vegetative photosynthetic cells along the filaments of the cyanobacterium Aphanizomenon ovalisporum (A. ovalisporum) (strain ILC-164) differentiate ...
