Reduced lifespan, chemotaxis defective, co-suppression of transgenes in somatic cells. Maintain under normal conditions. Reference: Hundley HA, et al. RNA. 2008 Oct;14(10):2050-60.

Chemotaxis deficient. Transgenes are silenced in this background. Reference: Reich DP, et al. Genes Dev. 2018 Feb 1;32(3-4):271-282. NOTE: In the referenced publication, irregularities were noted in the adr-1(gv6);adr-2(gv42) null strain, which were ascribed to background mutationsint hat strain. This strain -- adr-1(uu49);adr-2(uu28) -- was generated Crispr/Cas9 targeted mutation and phenotypes are more consistent with another null strain, adr-1(tm668);adr-2(ok735).

T20H4.4. Homozygous. Outer Left Sequence: CTCCATATTCGCTTCCGTGT. Outer Right Sequence: AGAACACGCTCTTCGTCGAT. Inner Left Sequence: CACGATGCTGCATGAGATTT. Inner Right Sequence: AGCTCGCTTCCAATCTTCAA. Inner primer WT PCR product: 2144. Attribution: This strain was provided by the C. elegans Gene Knockout Project at the Oklahoma Medical Research Foundation, which was part of the International C. elegans Gene Knockout Consortium, which should be acknowledged in any publications resulting from its use.
