Sequencing results

Sequencing results from 27/9 samples arrived and were analyzed by nucleotide BLAST.

Construct Sequencing
result 		Blastn
result 		Comment
pEX.N-TAT⋅SOD⋅His 3 pEX.nTAT.SOD.his 3_premix Blastn Verified. Three silent mutations in His tag; does not alter a.a. sequence.
pEX.N-TAT⋅SOD⋅His 4 pEX.nTAT.SOD.his 4_premix Blastn Not verified. Incorrect construct.
pSB1A2.RBS.yCCS 3 pSB1A2.RBS.yCCS 3_premix Blastn Partly verified. Three mutations found: (1) Single base deletion in yCCS sequence, causing a frame shift and an extended open reading frame; (2) Insertion between SpeI and PstI, not affecting expression of cloning; (3) Point mutation in PstI site, disabling PstI restriction. Mutations (1) and (3) are both quite unsure, as the sequencing quality in this area is very low. New sequencing from VR will be sent.
pSB1A2.RBS.yCCS 4 pSB1A2.RBS.yCCS 4_premix Blastn Partly verified. Four mutations found: (1) Point mutation changing a K codon to T; (2) Single base deletion in yCCS sequence, causing frame shift; (3) Insertion between SpeI and PstI, not affecting expression of cloning; (4) Point mutation in PstI site, disabling PstI restriction. See comment
pSB1K3.N-TAT⋅SOD⋅His 4 pSB1K3.nTAT.SOD.his4_premix Blastn Verified. Three silent mutations in His tag; does not alter a.a. sequence.
pSB1K3.N-TAT⋅SOD⋅His 5 pSB1K3.nTAT.SOD.his5_premix Blastn Verified. Three silent mutations in His tag; does not alter a.a. sequence.
pSB1K3.N-Tra10⋅SOD⋅His 5 pSB1K3.nTra10.SOD.his5_premix Blastn Verified. Three silent mutations in His tag; does not alter a.a. sequence.
pSB1K3.N-LMWP⋅SOD⋅His 1 pSB1K3.nLMWP.SOD.his1_premix Blastn Verified. Three silent mutations in His tag; does not alter a.a. sequence.

pSB1C3.N-LMWP⋅SOD⋅His 4 pSB1C3.nLMWP.SOD.his4_premix Blastn Not verified. Incorrect construct.
pEX.SOD pEX.SOD_premix Blastn Partly verified. Insertion found between SpeI and PstI; does not affect expression.
pEX.yCCS 5 pEX.yCCS 5_premix Blastn Partly verified. Insertion found between SpeI and PstI; does not affect expression.
pEX.SOD⋅His pEX.SOD.his_premix Blastn Verified. Three silent mutations in His tag; does not alter a.a. sequence.
pEX.His⋅SOD pEX.his.SOD_premix Blastn Verified. Three silent mutations in His tag; does not alter a.a. sequence.

Plasmid prep

From 28/9 ON cultures

Spun down ON cultures 10 min, 3000 x g. Decanted supernatant and stored pellets in -20 °C ON for later plasmid prep.

Sorting glycerol stocks

Started sorting our glycerol stocks into a spreadsheet for future reference.

Agarose gel verificaion

I ran an agarose gel 1 % 100 V on the colony PCR products from yesterday to check if I had any inserts.

Colony PCR

I ran a new colony PCR on the samples I did not have a possitive result on from the gel above.

The samples for this screen are:

IgG_LMWP_N, _TAT_N, _Tra10_N, protein A_LMWP_N_pex, _TAT_N_pex & _Tra10_N_pex

I screened 8 colonies/dish.

PCR master mix:

  • MgCl2 8ul
  • phusion buffer 5X 80ul
  • dNTP 8ul
  • primerR 24ul
  • primerF 24ul
  • polymerase 8ul
  • H2O 240ul

Agarose gel verificaion

Overnight culture

I inoculated Fusion EA colony 1 & 3 and Fusion NS colony 1 & 2 each in 12 ml LB with 24 ul chloramphenicol resistance.

Digestion

I digested IgG protease and protein A in the bank vector C in order to perform a gel clean up of the genes and insert them into a pMa-His AS vector.

Digestion:

  • H2O 15 ul
  • DNA 2 ul
  • Fastdigest buffer 10X 2 ul
  • Restriction enzyme NgoMIV 1 ul
  • Restriction enzyme SpeI 1 ul (Add after 1.5h incubation in 37 °C)
