PLASMID ASSEMBLY PLAN
NOTEBOOK ENTRIES
6/19:
made high school presentations
re-cultured Syk and Lyn
designed Lyn-TEVp fusion
-Syk and Lyn concentrations found to be only ~15 ng/uL, so need to grow new cultures and re-miniprep

Golden Gates for CD79A, CD79A-TCS-Gal4, Syk
-all of the originally ordered primers have arrived
-CD79B PCRs failed again, even with DMSO
-new CD79B primers designed/ordered
-when loading the gel, the Lyn-stop wouldn't fill the wells, but instead seemed to float up out of the gel on top of the TAE - ?
6/26:
redid Syk-15aa and Lyn PCRs using DMSO

designed sequencing primers
pUC19 competence
6/28:
miniprepped CD79A, CD79A-TCS-Gal4, Syk

6/30:
miniprepped Lyn, Lyn-mKate, Lyn-TEVp, Syk-TEVp, Syk-eYFP
7/1:
digested and gelled pENTR Syk, Syk-eYFP, Syk-TEVp, Lyn, Lyn-mKate, Lyn-TEVp, CD79A, CD79A-TCS-Gal4
-Lyns and Syk-eYFP failed
PCRed CD79Bs using new primers; Gmab H and L gBlocks
ran gel extraction on Gmab H and L PCR products
digest-verified pENTR CD79A, CD79A-TCS-Gal4, Syk, Syk-TEVp
7/3:
digested and gelled redone Syk-eYFP and Lyns
-failed again
7/7:
digested and gelled pENTR Lyn, Lyn-mKate, Lyn-TEVp, Syk-eYFP, CD79B, CD79B-TCS-Gal4, Gmab H, Gmab L, pEXPR CD79A, CD79A-TCS-Gal4, Syk, Syk-TEVp
-CD79B, Lyn, Syk-eYFP questionable; Lyn-TEVp, Lyn-mKate failed
digest-verified pENTR CD79B, CD79B-TCS-Gal4, Gmab H, Gmab L; pEXPR Hef1a:CD79A, Hef1a:CD79A-TCS-Gal4, TRE:Syk, Tre:Syk-TEVp
7/9:

7/11:
ran PCR screen for Syk-eYFP, Lyn, Lyn-mKate, Lyn-eYFP
-all the Syk-eYFPs failed; each of the Lyns had a few that might have worked
ran gels for CD79B-TCS-Gal4
7/12:
ran screening gel for CD79B
-some seemed to work
7/16:
digest-verified pEXPR Hef1a:Gmab L, Hef1a:Gmab H

-seemed to have some that worked for each
7/27:
Western blot for Syk (first try)
-inconclusive since errors in setup, protocol, etc.; no bands
7/29:
digested and gelled pENTR Syk-eYFP, pEXPR Lyn-mKate
-Syk-eYFP failed, but Lyn-mKate worked
7/30:
digested and gelled pEXPR Lyn-TEVp
-all failed
8/1:
Syk western blot (second try)
-successful this time
-results: Ramos and HEK293 cells both have high levels of endogenous Syk.
BCR membrane localization experiment (second try)
-this time, had B cells to use as positive control (also used this control data for next experiment)
-bleedthrough problems in cytometry data, but seemed to be some visible localization
8/2:
ran gels for pEXPR Lyn-TEVp, Syk-eYFP
-Syk-eYFP seemed to work, but Lyn-TEVp didn’t
8/7:
BCR membrane localization experiment (third try)
-blind transfection to avoid bleedthrough problems
-showed that there was localization, but only a small amount (~1.7%, as opposed to ~95% in B cells)

ran gels for pEXPR Lyn, Lyn-TEVp, TRE:Syk-eYFP
-seemed to fail
8/14:
ran gels for Gibsons, pEXPR Gmab L, CD79A, CD79B
