News Finding: Researchers saw that the more the person shivered, the more irisin the body released.
Paper Finding: MS analysis identified a unique peptide, mapped to the known sequence of irisin, only within the 32 kDa and 24 kDa bands ( Figure 1B) .
News Context: This means shaking from the cold or going for a jog could potentially create the same fat-busting opportunities. Researchers saw that the more the person shivered, the more irisin the body released. About 10 to 15 minutes of shivering released the same amount of irisin as riding a bike at a moderate pace for an hour.
Paper Context: Deglycosylation reduced the size of a 32 kDa band to 24 kDa, corresponding to reported molecular weights (MWs) of glycosylated and deglycosylated irisin, respectively ( Figure 1A ) . MS analysis identified a unique peptide, mapped to the known sequence of irisin, only within the 32 kDa and 24 kDa bands ( Figure 1B) . These results thus validated immunoblot identification of circulating irisin in humans.
