the fibrous long spacing collagen formed by adding α1-acid glycoprotein
was studied in detail.The pH of the mixture collagen and α1-acid glycoprotein was changed by dialysis.In each pH stage
stable intermediate structures were resolved by atomic force microscopy(AFM).The reliable and high-resolution images were obtained.The intermediate morphologies and diameters in every stage are observed by correlation the fibil diameters with length-wise growth in native type fibils and hy comparing the diameters and their morphologies of segmental long spacing collagen crystallites.These experimental studies demonstrated clearly the existence of intermediates in the formation process of fibrous long spacing collagens.
