Isopropyl Î²-D-1-thiogalactopyranoside (IPTG) is a molecular biology reagent.This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator.or induction, a sterile, filtered 1 M solution of IPTG is typically added by 1:1000 dilution into a logarithmically growing bacterial culture, however, different final concentration of IPTG may also be used.
Climb Mt Warning / Wollumbin. Be the first in Australia to see the sunrise from the top of Mt Warning.

This route is also referred to as the Heliotrope Ridge route, as the approach to the glacier follows that geographical feature. The trailhead on the north side of Mount Baker is at 3700 feet, and the hike to camp is about 4.5 miles on a nicely maintained hiker's trail.After a gear check at AAI's headquarters, we drive to the trailhead and hike to a camp below the Coleman Glacier's icefall at approximately 5500 feet.e ascend Pumice Ridge for a few hundred feet to the base of the Roman Wall, which is the last obstacle on the way to Mount Baker's 10,778-foot summit. The Roman Wall is nearly 1000 feet of 35-45 degree snow and ice that rolls over onto the summit ice cap of Mount Baker.
