Methods for generating large-scale gRNA libraries should be simple, efficient and cost-effective. We describe a protocol for the production of gRNA libraries based on enzymatic digestion of target DNA. This method, CORALINA (comprehensive gRNA library generation through controlled nuclease activity) presents an alternative to costly custom oligonucleotide synthesis.

Mycobacterial pathogenic strategies remain poorly understood. The slow growth rate of most species, the impenetrable nature of the cell-wall, and the hazards of working with pathogens make mycobacteria difficult to study and are largely responsible for our poor understanding of these organisms. In this video we will demonstrate the technique of electroporation, which involves subjecting cells to a brief high electrical impulse to allow the entry of DNA. It is the most widely used method for...

In utero electroporation is an important technique for studying the molecular mechanisms that guide the proliferation, differentiation, migration, and maturation of cells during neural development. Electroporation enables the rapid and targeted delivery of material into cells by utilizing electrical pulses to create transient pores in cell membranes. Although electroporation has traditionally been used in in vitro studies, scientific advancements have now broadened its utilization to intact...

Construction of a fosmid library with environmental genomic DNA isolated from the vertical depth continuum of a seasonally hypoxic fjord is described. The resulting clone library is picked into 384-well plates and archived for downstream sequencing and functional screening by the application of an automated colony picking system.
FAQs
The electrical pulse briefly creates pores in the cell membrane, allowing library DNA to cross into cells. Pulse conditions therefore influence whether introduced DNA produces viable recombinant clones rather than merely entering cells. In practice, conditions are optimized alongside cell competency, DNA input, and recovery so the recovered population retains more of the library’s sequence diversity.
Library size matters because it indicates how many viable recombinant clones are available to represent sequence diversity. A larger recovered population can provide broader representation for downstream screening, while a smaller one may leave less of the intended library represented. This makes clone count a practical indicator of whether the library can support searches for immune binders or pathogen-associated targets.
Cell competency, DNA input, pulse conditions, and recovery all affect the number of viable recombinant clones recovered after electroporation. Improving these factors can increase represented diversity, but the relevant outcome is not DNA delivery alone. Researchers need enough surviving, selected transformants to quantify library size and estimate coverage for subsequent screening.
The measured library size is an observed count of viable recombinant clones after cells recover and are selected. Library diversity is the sequence variation that this population can represent. Keeping these ideas separate helps researchers interpret whether a screening collection is sufficiently represented, rather than treating DNA input as the final measure of experimental success.
The workflow begins by introducing recombinant library DNA into cells with a brief electrical pulse. Cells then undergo recovery, followed by selection to identify viable recombinant clones. Researchers quantify the resulting transformants and use that measurement to estimate library coverage. This sequence connects the electroporation step with the population size available for downstream screening.
After recovery and selection, transformants are quantified as viable recombinant clones produced from the introduced library. Their number provides an estimate of how much sequence diversity the recovered population can represent. The measurement therefore helps researchers judge whether the library has sufficient coverage for a planned screen, while also revealing when optimization may be needed to improve representation.
In immunology and infection studies, library size helps evaluate collections containing antibody, peptide, or antigen variants. Researchers can use these libraries to identify immune binders and pathogen-associated targets. A sufficiently represented clone population strengthens the basis for downstream screening because more of the intended variant sequence space remains available for evaluation.
An insufficient library size means fewer viable recombinant clones are available to represent the intended sequence diversity. As a result, antibody, peptide, or antigen variants may be less completely represented during screening. Optimizing pulse conditions, cell competency, DNA input, and recovery can improve diversity and strengthen the reliability of downstream searches for immune binders or pathogen-associated targets.
