Escherichia coli |
E. coli. Show Description
Bacteria. E. coli HT115(DE3) bacterial strain carrying pGC8. pGC8 is a partial cDNA of him-14 (ZK1127.11) cloned into the Timmons and Fire "double T-7 vector" L4440. The source of the cDNA is Yuji Kohara's clone yk240h12. pGC8 was constructed by inserting the 1.65kb KpnI/SacI fragment of the him-14 cDNA (from base pair 1071 to 192 base pairs beyond the stop codon) into the same sites in L4440. HT115(DE3) carrying pGC8 should be selected in the presence of 50 um/ml tetracyline and 100 um/ml ampicillin. Prior to an actual feeding experiment, it can be grown in liquid in the presence of amp alone (no tet) and then seeded onto NGM plates containing amp and 1 mM IPTG. This technique does not work well if the cells are old; therefore, the strain should be seeded onto IPTG-containing plates from a fresh overnight that was grown from a colony on an amp/tet plate. Biosafety Level: BSL-1. For more info see http://www.wormbook.org/wli/wbg17.1p32/

HT115(DE3) |
Escherichia coli |
E. coli [F-, mcrA, mcrB, IN(rrnD-rrnE)1, rnc14::Tn10(DE3 lysogen: lacUV5 promoter -T7 polymerase]. Show Description
Bacteria. Genotype: F-, mcrA, mcrB, IN(rrnD-rrnE)1, rnc14::Tn10(DE3 lysogen: lacUV5 promoter -T7 polymerase) (IPTG-inducible T7 polymerase) (RNAse III minus). This strain grows on LB or 2XYT plates. This strain is tetracycline resistant. Researchers using this strain should test for expression by transforming in one of the plasmids from the Fire Vector Kit (1999) (pLT76, e.g.) using standard CaCl2 transformation techniques. Biosafety Level: BSL-1.

iOP50 |
E. coli |
OP50 E. coli, rnc14::(delta)Tn10, lacz(gamma)A::T7pol camFRT Show Description
RNAi-capable OP50 strain. Tetracycline & Chloramphenicol resistant. Uracil auxotroph. E. coli B. Biosafety Level: BSL-1. Standard OP50 (CGC) was rendered RNAi competent through two modifications by phage transduction. The OP50 RNase III (rnc) allele was replaced with the deletion allele (rnc14::?Tn10) found in HT115(DE3), and a genomically encoded IPTG-inducible T7 RNA polymerase (lacz?A::T7pol camFRT) was introduced.

NJF01 |
Escherichia coli |
NJF01 (F-, lambda- lysA0::Tn10 IN(rrnD-rrnE)1, DE3, (delta)rnc-38). Show Description
Bacteria. NJF01 originates from E. coli ET505 (F-, lambda- lysA0::Tn10 IN(rrnD-rrnE)1), modified with DE3 and (delta)rnc-38. The E. coli is lysine auxotroph and resistant to kanamycin and tetracycline. IPTG induces expression of the T7 polymerase. Grow at 37 °C on LA plates or in LB liquid medium.
