PeerJ line numbers
Line numbers changes on PeerJ PDF even when it is preformated in DOCX. This create a headache when line numbers are cited in response letter. I tried different page margin and format. The lines number still changes between my DOCX and PeerJ pdf.

lab 4
1. The students may have to work to see the Brownian Movement. Don’t let them give up :)
2. It is always a good idea to have the students start section 3 with the potatoes first thing. That way as they are waiting the 45 minutes for the potatoes to sit in the NaCl, they can do the other parts of the lab. After they clean their glassware, have them put the test tubes upside down in the rack with paper towels underneath. It will allow the water to drain before the next class arrives. Things have been going very well on the cleanliness aspect – Thanks! This one is the last really messy lab we have, so keep up the good work.
3. ** Filtration Exercise **
I have posted a modified procedure for the filtration exercise on blackboard. Please let your students know about the new procedure. I basically increased the amount of copper sulfate to use and changed the wood charcoal to some that is powdered (rather than the granular stuff that was there before). This should help things get dissolved and then filter out at the end. Please let me know if you have any questions about this.
4. Paramecium Video: Please refer to my previous email about posting youtube links and the two questions associated with the videos.
5. Feel free to use any of the live specimen for your quizzes next week – I have more if you need to use some. It would be good practice for their lab practical.

Also: tried "sudo nano -w /etc/enviroment", but it did not work.
RNAseq analysis protocol
"Quality of the reads was analyzed with FastQC v0.10.1, and trimming of low-quality reads was performed with Trimmomatic v0.33 [1]. The reads were aligned to the hg19 version of the human genome using the software TopHat v2.0.13 [2]. The Human UCSC hg19 genome annotation was downloaded from Illumina’s FTP repository located on ftp://igenome:G3nom3s4u@ussdftp.
illumina.com/Homo_sapiens/UCSC/hg19/Homo_sapiens_UCSC_hg19.tar.gz. Expression quantification was obtained with CuffLinks v2.2.1, CuffMerge v1.0.0 and CuffDiff v2.2.1. "

advantages of the 561-nm (Yellow-Green) Laser for the flow cytometry.
a brief list of advantages of the 561-nm (Yellow-Green) Laser for the flow cytometry.
all the RFPs, GFP, CFSE and Fitc when really bright bleed into the PE channel horribly when using just a 488 laser. If you are using the 561 for PE there will be almost no spillover.
— tdTomato detection (fluorescent protein 283% brighter than eGFP)
— MitoTracker Orange (accumulation is dependent upon membrane potential and the dye is well-retained after aldehyde fixation)
— CRISPR-Cas9, an emerging gene-editing (“genome surgery”) tool that frequently uses mCherry reporters. And yellow-green laser is required for optimal excitation of this fluorescent protein
— up to 3.7-fold increase in the stain index with antibodies conjugated with PE and PE based tandem dyes
— greatly expands the choice of fluorochromes

Evolve manual pipettes
I wanted to take a moment to remind you of our newest product offering and current promotions. Our new Evolve manual pipettes provide an innovative way of changing volumes which will speed up daily pipetting. Instead of changing volumes by twisting the plunger, which can take a long time going from one end of the range to the other, our Evolve pipettes have three dials so you can change each digit independently of each other. This new technique will reduce the amount of time by more than 50% compared to your current manual pipettes. They are extremely ergonomic and light and come with two different plunger springs to customize the feel that you want. These pipettes still come with the Integra Grip Tip interface which ensures a supreme tip attachment without banging them on while also guaranteeing zero issues with tips falling off or leaking. We offer single and multichannel models with a range of 0.2ul-5000ul across many different pipettes.
In conjunction with this launch, we are running two promotions with very aggressive pricing that run for the rest of the year. The first is a trade in promotion. You can trade in any pipette in any condition for a huge discount. The second promotion is for a starter pack where you get the 20, 200, and 100ul single channels, 10ml reservoir sample pack, 3 cases of tips, and 3 shelf hooks.
I understand it is a lot to ask for you to convert your pipettes and tips; so I am willing to discuss the possibility of “buying back” some of your current tip stock. With this new aggressive pipette pricing and huge tip offer, I know you will not find a better value. I look forward to working with you.
