This strain will be shipped as bacteria in an LB stab. Upon receipt, requesting scientists should restreak the strain on an M9 minimal plate. After restreaking on M9 to confirm the presence of the F', scientists can grow the strain in liquid LB.
M9 minimal medium agar plates: To prepare 500 ml, autoclave 439 ml H2O with 7.5 g Bacto-agar and a stir bar. When agar has cooled to approximately 65°C, add 50 ml 10X M9 salts, 1 ml 1 M MgSO4, 10 ml 20% (w/v) glucose and 0.5 ml 100mM CaCl2 and then pour plates. Plates can be stored indefinitely at 4°C in sealed plastic bags. (Alternatively, M9 plates can be purchased from Teknonva: https://www.teknova.com/content/teknova/us/en/products/product-page.html/m1260.html).

Genotype= aspC tyrB trpA trpB glyA serB
Precursor strain = RF14
Modified from the parent Escherichia coli BL21(DE3) strain
Selective amino acid labeling (and/or requirement) = Asp, Tyr, Trp, (Phe), Gly, Ser+++++
+++++ RF15 has knockouts in aspC, tyrB, trpA, trpB, glyA and serB genes and requires the presence of L-Asp, L-Tyr, L-Trp, L-Gly plus L-Ser for growth in M63 minimal medium, but it does NOT grow in the presence of L-Asp, L-Tyr, L-Trp, L-Gly, L-Ser plus L-Cys (either in the presence or absence of L-Ala) (i.e., L-Cys inhibits the growth of RF15)
Please visit the following links for additional details on this strain and selective amino acid labeling-

Note that these strains are NOT competent cells and one needs to make them competent before use.
Supplemental documents contain a list of PCR primers used for verification of each knocked-out gene as well as an image showing PCR results for this strain.

Genotype= aspC tyrB ilvE avtA yfbQ(alaA) yfdZ(alaC)
Precursor strain = RF18
Modified from the parent Escherichia coli BL21(DE3) strain
Selective amino acid labeling (and/or requirement) = Asp, Tyr, Phe, Ile, Leu, Val####
#### RF21 has knockouts in the four general transaminase genes of E. coli (aspC, tyrB, ilvE, and avtA) and is found to require the presence of L-Asp, L-Tyr, L-Phe, L-Ile, L-Leu plus L-Val for slow growth in M63 minimal medium. Although RF21 strain has further knockouts in yfbQ (alaA) and yfdZ (alaC) genes, it is NOT an L-Ala auxotroph, either (requiring the presence of L-Asp, L-Tyr, L-Phe, L-Ile, L-Leu plus L-Val for slow growth in M63 minimal medium, like RF18).
