| 摘要 |
The invention relates to a tissue specific protein, i.e. a substance which is a constituent of parenchymatous tissues, and to a process for preparing the same. The tissue protein is characterized by a protein proportion of 94+/-3%, essentially consisting of alpha -amino acids, an amino acid analysis of - Variation -Mol % coefficient (%) -lysine 5,64 12.7 -histidine 1.05 15.0 -arginine 3.83 9.2 -aspartic acid 9.84 6.8 -threonine 4.33 15.7 -serine 4.78 8.2 -glutamic acid 11.29 3.5 -proline 6.41 9.2 -glycine 8.65 9.8 -alanine 7.51 6.4 -cystine/2 2.11 12.6 -valine 6.68 7.9 -methionine 0.98 14.5 -isoleucine 3.32 7.4 -leucine 14.43 4.2 -tyrosine 5.10 14.9 -phenylalanine 3.08 13.5 -and tryptophan 1.14 11.4 - a carbohydrate proportion of 5.4+/-2.2% consisting of 3.0+/-1% of hexoses, 1.2+/-0.5% of hexosamine, 0.2+/-0.2% of fucose, and 1.0+/-0.5% of neuraminic acid, a sedimentation coefficient S20,wc=0.1 of 3.5 S+/-0.
