01.07.09, 8:30-13:00 Manuel, Hannes


*SDS-Gel:

SDS-Gel of the expression; Lanes: Marker (prestained broad range 7-200 kDa, T7+Tt 1h..2h..4h, T7+Aa 1h..2h..4h, BL21+Aa 1h..2h..4h


*PCR with the purified PCR product from the 30.06.09 as template. Different program: nr. 25 IGEM.AM -> no result. next step should be to do a gradient PCR this afternoon. Just talk to Sven to get the details.
*inoculated T7+Tt, T7+Aa and BL21+Aa in 3 ml LB-Kan for a new round of expression at 27°C.
*idea from Sven: do a westernblot on the isolated proteins from the AGO-Expression to find out whether the AGO-protein is present or not.

01.07.09, 14:00-18:00 Isabel, Laura


*gradient PCR from 60°-70°C with 8 tubes each of vector 258 diluted and undiluted, we put it in the cold room -> gel has to be done tomorrow
*we made 100ml 1M Tris-HCl pH=6,8
*we inoculated 4ml LB with cells from the CAT-vector #258 glycerol stock and put it into the 37°C room
*to do: -plasmid preparation of the inoculated cells including the CAT vector
-test-digest of 1,5 µg of the plasmid with EaeI (cutting 3 times, fragments: 2268, 331, 1757 bp)
-fetch new dNTPs of the NEB freezer (snd floor)
-alterations of PCR-program: only one step but 30 times, with temperature gradient 55-65°C (Sven can help)

02.07.09, 09:00-18:00 Hannes, 14:00-18:30 Laura


*AGO: expression of Aa and Tt (T7+Tt, T7+Aa, BL21+Aa) at 27°C. samples after 0, 1.5 and 4 hours
*plasmid preparation of inoculated labvector 258
*agarose gel with gradient pcr -> didn't work
*nanodrop with primer and labvector -> concentrations were good
*search for a 5 cutter restriction enzyme for the test digest for tomorrow: FOKI!
*NanoDrop data

*SDS-Gel of the samples from yesterday.
*Laemmli buffer mixed and aliquoted -> -20°C

SDS-Gel of the expression; Lanes: Marker (prestained broad range 7-200 kDa, T7+Aa 1h..2h..4h, T7+Tt 1h..2h..4h, BL21+Aa 1h..2h..4h

06.07.09, 09:00-19:00 Hannes, Laura, Caro, Manuel


*we did a agarose gel from the pcr product, cut the band and eluted the DNA. As the concentration only was about 50 ng/µl we did a new gel with 3 times the amount on pcr product (150 µl). We cut the bands, eluted the DNA and got a concentration from about 100 ng/µl. We used both eluted DNA samples for the restriction digest with HindIII and MfeI (4 hours at 37°C).
*After the restriction digest had been incubated for 4 h (37°C) we purificated it
*Because of the fact that we eluated with 50ul and not with 30ul (better for the following ligation) we got a concentration of only 87,7ng/ul
* We heat up the sample to 50°C for 1 min and measured again. Finally we got a concentration of about 100 ng/ul
* sample Cat gene stored in the -20 °C freezer
* Inoculation (each 10 ml) for Protein expression and Glycerolstocks
* Nanodrop data:

*digestion of the pMal-Vektor with HindIII and MfeI (both from the lab freezer), didn't work. Maybe the MfeI enzyme was bad (expired 2005)

Plan for today
*Transformation of ligations His+Dig, Strep+Dig, His+FluA, Strep+FluA in pMAL respectively (Isabel, Sarah)
*generate an inventory of all stocks and plasmids in our freezers (Isabel, Sarah, Gerrit)
*PCR with M13-DNA and GenIII-Primers (Max, Laura)
*PCR with complementary linkers (short, middle and long) to hybridise(Max, Laura)
*SDS-Gel of purified Argonaut proteins (Hannes)
*scan gel pictures and upload them into wiki (Christoph)
*order of new equipment like pipettes, racks etc (Timo)
*analyse background activity of E. coli (Gerrit)
*write the project abstract for official wiki (Max)
*modelling and planing length of oligos(Rüdiger) Nanodrop data

*Nucleic acid
