The observation of a novel α-zein in De *-B30 approximately 2 kD larger than the mature 19-kD α-zeins is consistent with a defective signal peptide, and this hypothesis is reinforced by the fact that De *-B30 is genetically linked with a cluster of 19-kD α-zeins (Soave and Salamini, 1984). These results suggest that 19-peptide inhibits the growth and metastases of poorly differentiated gastric carcinoma cells, primarily by inducing apoptosis. USA.gov.

The tumors were measured and examined by western blotting, histopathology, and terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling assay. Although the molar concentration of the peptide 1D required to suppress the aggregation of denaturing ADH was about 8-fold higher than that of αA-crystallin, this is first report that a 19-amino acid peptide displays anti-aggregation property similar to that of αA-crystallin in vitro. Via a human-to-human transmission, the virus is known to be very aggressive and has now infected more than 13 million around the world and caused the deaths of more than ½ million people (data from July 15, 2020). NLM In 7-15 minutes peptides are linking together with dendritic cells, which transfer them to lymph nodes, where peptides do 'transfer' and move with blood flow to the necessary organs and tissues.
