1 Since the interaction of peptide fragments derived from alpha 2-macroglobulin with Con A requires the presence of mannose and/or glucose residues, we have also examined if there are any correlations between the levels of mannose and glucose in alpha 2-macroglobulin and SLE. Mannose alpha-2-macroglobulin Homo sapiens
2 The concentration of mannose (38 +/- 60 micrograms/mg protein) in alpha 2-macroglobulin derived from SLE patients was significantly higher than normal donors (mannose, 4.8 +/- 1 micrograms/mg protein) however, the concentration of glucose in alpha 2-macroglobulin derived from SLE patients when compared to normal donors was not statistically significant, 18 +/- 20 micrograms/mg protein in SLE versus 2 +/- 0.5 micrograms/mg protein in normal donors due to high variation between samples. Mannose alpha-2-macroglobulin Homo sapiens
