Te-rich films had higher carrier concentration but slower mobility than Bi-rich films.
In addition to observation of the (SQ1A SQ1B 2 quadruplex, a much slower mobility species is also observed (Figure 2, higher order structures).
Importantly, the displaced strand exhibited slower mobility in the presence of streptavidin (Fig. 7 8).
A slightly slower mobility of PERK protein in suspension is probably indicative of the phosphorylation.
Indeed, the complex MexA-OprM trimer is moving with a slower mobility than the respective free protein and trimer.
As APP is trafficked through the secretory pathway, a series of glycosylation events occur leading to a mature, or fully glycosylated, protein with slower mobility on SDS-PAGE.
A comparably slower mobility in acrylamide gels was previously described for SPANX-A/D proteins [3], [6] and is likely due to clustering of charged amino acid residues.
A cross-reacting slower mobility polypeptide (Mr ∼240 kDa), prominently detected in the pancreas, is probably an unrelated protein recognized by anti-PLEKHA7 antibodies, based on two arguments.
The slower form of Rb-ser780P is consistent with it being a hyperphosphorylated form of Rb due to its late-G1 appearance and slower mobility.
The relative misincorporation of G versus incorporation of A is readily visualized by the intensity of a band with slower mobility in a doublet band.
Interestingly, for each form of recombinant OR2, another band of slower mobility whose size was increasing in proportion to the size of the tag could also be detected with all antibodies (Figures 1B and 1C).
