but the bands are slightly lower than they should be.
Ran extraction gel for PCR products: HL1. LY65, LT67, LY68, LT70, PY, PT

Also inoculated pEXPR_hEF1a: LilrB2.
Midiprep party tomorrow!
eYFP-Cofilin:
Plate had lots of white colonies and a few blue ones. Not expected. Expecting a lot of backbone re-ligation. Picked 10.
Will miniprep tomorrow.
AG
Tissue culture
July 24
SS
Miniprepped eYFP:Cofilin colonies
Ran digest gel (PstI, ApaI, Cutsmart)
2 might have worked
Sent for sequencing.
Turns out, didn't work. eYFP missing.

July 25
SS
Did midipreps. Very strange distribution of concentrations:
LilrB2 1: ~1200
LilrB2 2: ~700
PirB 7: ~4000
PirB8: ~300
Digesting midipreps just in case.
LilrB2: XbaI, ApaI
PirB: ApaI

LilrB2's are weird. Running undigested controls.
LirB2 DNA is contaminated!
Correct band pattern is most definitely there. Which means all parts: hEF1a promoter, LilrB2 gene and backbone are
there.
AG
Tissue culture
July 26
SS
Run DNA for gel extraction. Also look to see if other, verified DNA contaminated or not.
Pick colonies fusions
Transform
Transforming with L2 and L3 DNA (L24, L34).

July 27
SS
Minipreped a gazillion fusions.
4/5 cofilins seemed to work. Had 3 fragments. Means at least 2 of the goldengated parts are present. Will digest
with ApaI tomorrow to check if 3rd is present.
PirBs didn't seem to work, will pick more colonies.
LilrB2 didn't work
Will pick pEXPR_LilrB2 colonies.
AG
Tissue culture
July 28
SS
Cofilin 1, 3, 4, 5 worked, need to do another digest.
LilrB2:TCSG4 1, 4, 5 might have worked. Strange extra band on top. Will do different digest.
LilrB2: YFPL none worked. Will miniprep more.
PirB:TCSG4 none worked.
PirB:YFP none worked.
Cofilin worked! Sending all 4 for sequencing, 'cuz PCRs and mutations, ya know?
LilrB2:TCSG4 did not work. Will have to miniprep more.

Made glycerol cell stocks of all the cofilins, but due to some mistake, the labels got erased. So, unless they all
worked, I'll just re-transform one that worked.
Making glycerol cell stocks of pEXPR_hEF1a: LilrB2 (L2 and L3)

July 29
midipreped pEXPR_hEF1a:LilrB2.
All the eYFP:Cofilin worked! LRed today.

SS
Miniprep PY, LY, pENTR_TEVpCofilin
Verify Minipreps
Transform hEF1a:YFPCofilin
Pick TREt:YFPCofilin Colonies
All 4 pENTR_TEVpCofilin worked!
The others didn't work. Given the lack of blue colonies, I'm thinking backbone religation/only one part present
(probably YFP). Need to figure out something else.
Sequencing:
LilrB2TCSG4 seems to have worked! 11 and 13 might have point mutations (high G content, unlikely). Will proceed with
12.
PirBTCSG4 seems to have worked, too! 13 seems to have a point mutation (high G content, unlikely). Will proceed with
11.

August 2
SS
Transform all LRs (hEF1a:PT, hEF1a:LT, hEF1a:TC, TREt:TC)
Pick hEF1a:YC colonies
Miniprep TREt:YC if it worked. Otherwise, wait for Brian. Worked.
Midiprep inoculate TREt:YC
Digest LilrB2TCSG4 with NcoI and PstI seperately.
Digest TREt:YC with ApaI

TREt:YFP_Cofilin 1, 2, 4 verified. Will midiprep 2.
Ran PT (pENTR_PirBTCSG4) to make sure it isn't contaminated).
The gel for PT had an extra band, but the sequencing results show that the TCSG4 is present and goes into the PirB
region. That means everything is in order.

August 3
SS
Took pEXPR TREt YC midiprep out of incubator
Took pEXPR_hEF1a:YC miniprep out of incubator

Midiprep pEXPR_PirBTCSG4VP16. The midiprep concentration was low, around 16. Probably because the culture didn't grow
very well.
Miniprep inoculating again.
Digest any YFP fusion minipreps we have to check for what segments are present and what went wrong.
