Biofuels are often called "CO2 neutral" in the sense that CO2 which is emitted in the course of their combustion has previously been fixed from the atmosphere via photosynthesis during plant growth.
The Scandinavian airline SAS got a penalty of €70.2 million, which was higher than would have otherwise been the case because it had previously been caught fixing prices in a separate case.
Cells that had previously been washed off the medium were fixed with 4% paraformaldehyde solution for 15 min. In order to permeabilize the cells, 0.1% Triton X-100 (Sigma) detergent was added to the prefixed cells for 15 min. Then, the cells were rinsed twice with phosphate-buffered saline (PBS).
48 hours after transfection, cells were plated at low density onto coverslips that had previously been coated with Matrigel, fixed, and immunostained for CD155 to confirm protein knockdown.
If the alleles that fix had previously been maintained by balancing selection, evolutionary responses will be influenced, at least in part, by how standing variation is maintained.
Majeed claimed that fixing was a "centuries" old practice and raised the names of Waqar Younis and Wasim Akram as two who had previously been involved.
Neither of the class II PI3K antibodies have previously been assessed for their reactivity on fixed human tissues.
