CL4176 C. elegans smg-1(cc546) I; dvIs27 X. Show Description
dvIs27 [myo-3p::A-Beta (1-42)::let-851 3'UTR) + rol-6(su1006)] X. Rollers. Temperature sensitive: needs to be propagated at 15C. Upshift larval animals to check that the worms get paralyzed and give offspring that arrest as eggs/early larvae. This strain produces low levels of beta amyloid peptide even when grown at low temperature, and therefore there is always some selection for loss of transgene copies. It is recommended to maintain growing stock plates at 15-16 degrees C by transferring small numbers of animals each generation rather than by "chunking", which increases the effective population size and therefore the chance of a relatively rare transgene loss, and then this revertant taking over the population. The strain should also be frozen shortly after being received. This strain can only be sent to academic users and not to commercial organizations.
