As you can see from the graphs of past temperature reconstructions (page 467 in this chapter by the IPCC), none of the curves suggest that temperatures 1,000 years ago matched those of today, let alone were much warmer.
Low-temperature SDS-PAGE (LT-PAGE) was performed for detection of SDS-resistant eNOS dimer and monomer as described previously [52].
To examine whether the increased eNOS protein level with dysfunctional enzymatic activity in senescent endothelial cells is the result of eNOS uncoupling, experiments with low temperature SDS-PAGE for detection of eNOS dimer/monomer were performed.
The samples were then split into 2 tubes, 1 µl of PNGase F (500 units) (New England Biolabs, Beverly, MA) was added to one of the tubes, and both samples were incubated for 16 h at room temperature before SDS PAGE.
To this end, we analyzed the samples incubated for different amounts of time at an elevated temperature in SDS-PAGE and Western blot.
Similarly, we analysed the whole cell lysates from milder induction at lower cultured temperature by SDS-PAGE without boiling denaturation, which separated the native EGFP proteins in soluble form from their non-native molecules in inclusion bodies [ 13].
To distinguish the monomeric from the dimeric form of eNOS, the latter of which forms a stable SDS-resistant homodimer under reduced conditions at low temperature, low temperature SDS-PAGE (LT-PAGE)/Western blot was performed according to a published method (Klatt et al., 1995; Kakoki et al., 2000) with minor modification.

Re "A Scientist, His Work and a Climate Reckoning" ("Temperature Rising" series, front page, Dec. 22): It is a tragic commentary on a 40-year decline in scientific literacy in America that the work of Charles David Keeling on rising carbon dioxide levels is so egregiously misinterpreted by conservative legislators and a significant fraction of the general public.
Re "Clouds' Effect on Climate Change Is Last Bastion for Dissenters" ("Temperature Rising" series, front page, May 1): Republican deficit hawks proclaim over and over that it is for the sake of their children and grandchildren that they are so greatly concerned about accumulating federal debt.
