Abstract
The introduction of ectopic DNA, such as plasmids, into yeast cells has for decades been a critical protocol for the study of this eukaryotic model system. We describe here an efficient transformation procedure for use in the fission yeast Schizosaccharomyces pombe. This method relies on chemical agents (lithium acetate, and polyethylene glycol) and temperature stresses, which ultimately facilitate transfer of the genetic material through the cell wall and plasma membrane without significant impact on the transferred DNA or the recipient cell. Using this protocol, we consistently see transformation efficiencies between 1.0 × 103 and 1.0 × 104 transformants per microgram of the plasmid with 108 S. pombe cells. The principal benefits and advantages of this method are its simplicity, efficiency, and relative speed of completion.
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 31 October 2018.
All research outputs
#14,376,243
of 23,023,224 outputs
Outputs from Methods in molecular biology
#4,226
of 13,166 outputs
Outputs of similar age
#240,504
of 442,361 outputs
Outputs of similar age from Methods in molecular biology
#432
of 1,498 outputs
Altmetric has tracked 23,023,224 research outputs across all sources so far. This one is in the 35th percentile – i.e., 35% of other outputs scored the same or lower than it.
So far Altmetric has tracked 13,166 research outputs from this source. They receive a mean Attention Score of 3.4. This one has gotten more attention than average, scoring higher than 64% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 442,361 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 1,498 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 66% of its contemporaries.
