The lab experience would not have been anywhere near the same if you weren't around to jostle things up.

*Ant: You were my mentor for the summer that I started and you were out of town for at least a week (what a first impression!). Joshing aside, you did do a great job showing me the ropes of the lab, helping me get things setup, and just otherwise guiding me along (even though I joked about you being my mentor, I really did appreciate it).

I don't know if you will read this, but let the record show that Nas was the most friendly and willing-to-help-y person I ever met. It was really neat to get to see the biologists in the lab; lending to the hybridization that I think is really the appeal and strength of biophysics. I do hope that you get your MD and work a good practice here
*Diego:Speaking of biologists, Diego is the main man. Although we didn't really interact too much, Diego did show me show me how Biologists and Physicists can work together great! I also want to thank you for all the funny stories and help with graduate applications that you provided me.
*Caleb:When Koch asked me "Do you know Caleb Morse?" I said "no" not knowing it was the same guy I saw at least 3 times a week when I tutored at CAPS. Caleb, you are a computer ''genius''! Thank you so much for helping me get the computers in line and being an overall cool guy. I enjoyed tutoring you in CAPS and it was all too amazing that we worked together for Koch
*Pat: Pat and I stated at the same time. Even though you are gone (and may not read this entry), thanks for being there as the other undergrad. Um, that may not sound as sincere as I want it to, but it was really great to have someone my age/level in the lab for me to relate to. It was also really fun to see you and Larry fight. We did have some fun times and I wish you the best as you also embark in grad school
*Andy: Oh Andy. I probably got on your nerves more times than you really cared for. Aside from that, thank you for "taking me under your wing" (I think it was voluntary, maybe Koch bribed you). You are one smart guy, and I'm glad that you took the time to share with me some of your knowledge. It was (and still is) hard to get the lab just they way you want it, but in the end, I think your changes are a great asset to the lab. You are an awesome teacher and have patience like few others (how many times have you surprised me by not blowing up at Larry). One more thing, I just want you to know that you have to coolest character in my comic, I was really surprised at how that worked out.
*Brigette: I guess my computer will always think your named is misspelled. I'm sad that we didnt really get a chance to know each other as you just stared just as I left. Thanks for letting me help you with the projects, even though I got in the way more that anything. You are a really cool person and I'm amazed that KochLab got a girl student and you'll bring some civility to this lab (maybe, maybe not).

To Do

  • Write my last official notebook entry as a KochLab member :(
  • We are running out of PEM, so I would like to make some more before I go
  • We got motility working yesterday, so Andy may want to continue to pursue that

Inventory

  • Brian had to leave, but i did give him a crash course on how to use the inventory page
  • Most of the pages are self-explanatory
  • Also note that chemicals and software inventory require an update to the google docs page
  • The optics section of the inventory is blank
    • My idea was to have it as a static page that just listed important opto-mechanics
    • Perhaps we can have a check in-check out system so we can keep track of who took what where and when

PEM

  • Andy, Brigette and I made 205ml of PEM a month or 2 ago and its getting low
  • I will try to make 200ml more and follow the exact steps I took last time
  • I will need NaOH and possibly HCL to titrate the buffer
    • We should have plenty of normal soln left from earlier buffer makings
    • We have 4 tubes of NaOH but no HCL, lets hope I dont screw up the titration

Procedure

  • Following what I did last time, I want the following:
    • 1mM MgCl2
    • 1mM EGTA
    • 80mM PIPES
  • I am using the following chemicals:
    • 1M MgCl2 in 50mL falcon tube made 2 years ago ( we used it in the motility assay yesterday and it was fine)
      • For 1mM in 200ml, I want .2ml (200uL)
    • EGTA powder, working weight 380.35
    • For 1mM in 200ml i need .07607g
    • PIPES powder, working weight 302.37
    • For 80mM in 200ml, I need 4.83792g
  • I will wash out a 250ml glass bottle with DI water then use DI water to suspend the salts
    • I will use the autoclaved DI water I made a month ago, that way we use it a up a bit since we have a fancy schmancy DI water machine
  • I filled up the jar with ~150ml of DI h20, now to add the powders
  • After addition of powders and washing it down with more DI water, I'm about 175ml
  • Powder Concentrations used:
    • 200ul MgCl2
    • .0768g EGTA
    • 4.8387g PIPES
  • Note: I used the "DI Water" in the spray bottle. It may be tap water, Andy and I both dont know who filled it up with what. Last time I made buffers I used the water in the spray bottle, hopefully it still works
  • Now to titrate

Titration

  • Starting Ph
  • added 25.8mL of 1M NaoH to get it to a Ph of 6.89
    • Thats 12.9mM of NaoH in 200ml soln of PEM

Test Drive

  • Andy is making motility stuff and is going to try my PEM, hope it all works!

DI H2O

  • I went ahead and emptied out all the squeeze bottles that are labeled DI water and replaced it with the stuff from our DI water machine

Final Note For KochLab

  • I would like to take a minute to thank each and every person in Koch Lab for this wonderful experience I have had over the past year and a half
  • Koch: Thank you for teaching a really great Jr lab. It was how you handled that little lab that really made me want to work for you in a real one (and boy was I not disappointed).

  • Ant: You were my mentor for the summer that I started and you were out of town for at least a week (what a first impression!). Joshing aside, you did do a great job showing me the ropes of the lab, helping me get things setup, and just otherwise guiding me along (even though I joked about you being my mentor, I really did appreciate it).

Thanks for letting me help you with the projects, even though I got in the way more that anything. You are a really cool person and I'm amazed that KochLab got a girl student and you'll bring some civility to this lab (maybe, maybe not).
