further democratize long-read sequencing for routine plasmid analysis & guide future efficiencies as tech improves.

Give it a spin at Google Colab (https://colab.research.google.com/github/MasaakiU/MultiplexNanopore/blob/master/colab/MultiplexNanopore.ipynb) or @GitHub (https://github.com/MasaakiU/MultiplexNanopore).

Congrats to HFSP postdoctoral fellow Masaaki Uematsu, who did it all (except write these toots)! /end

Do you (want to) use whole-plasmid sequencing (e.g. @plasmidsaurus) but are put off by $15/sample? Use SAVEMONEY—our (postdoc Masaaki Uematsu’s) algorithm that lets you mix 6 or more plasmids/sample & computationally de-mixes reads!

How it works: 1/n

Google Colaboratory

Incredibly, you can reliably mix together plasmids differing by as few as 2 bases & up to 6 (or even more) plasmids in a single sample, which lowers the effective cost of whole-plasmid sequencing to less than that of a single Sanger run! We hope that SAVEMONEY will... 5/n
SAVEMONEY has two basic parts: (1) pre-survey & (2) post-analysis. Pre-survey examines your plasmid maps and tells you which groups of plasmids to mix together. Post-analysis classifies, aligns, and generates consensus sequences for each plasmid in the mixture. 4/n
Multiplexing exists for long-read sequencing but typically involves extra barcoding or is geared toward those with their own sequencers. SAVEMONEY (Simple Algorithm for Very Efficient Multiplexing of Oxford Nanopore Experiments for You) is for users of 3rd party services. 2/n
Nanopore sequencing typically provides 100s of reads/sample to generate a consensus sequence. But Masaaki realized that w/prior information of expected sequence & Bayesian analysis, you can get sequences w/~30 reads/plasmid—in other words, money is being left on the table. 3/n

Glycans are sweet,
Nucleic acids—they’re fine.
Proteins are interesting,
But nothing beats #lipidtime!

🚨New manuscript: interorganelle lipid transport is rapid, & it is hard to quantify discrete steps in this network, mediated by lipid transfer proteins working at membrane contact sites between different organelles. We (Dongjun Liang & Lin Luan) harness chemoenzymatic tagging & super-fast #bioorthogonal chemistry to make fluorescent lipids that report on PM-to-ER phospholipid flux mediated by a family of lipid transfer proteins at these contact sites! https://doi.org/10.1101/2023.02.01.526230 #lipidtime #chembio

A phishing message from an account pretending to be me is going around my department.

I'm deeply offended by the typos and grammatical errors.

If the phisher uses "utilize," I swear I'll hunt them down and force them to copy lines from Strunk and White.
