Abstract

The invention relates to the field of technologies for detecting antiques, and discloses a method for detecting ancient wool fabrics by the aid of fluoroimmunoassay. The method includes A), arranging three antique samples in three perforated vessels A, B and C, washing the antique samples by the aid of PBS (phosphate buffer solution), adding rabbit anti-wool-keratin antibody diluent into the perforated vessel A, adding PBS into the perforated vessel C, refrigerating the perforated vessels, then adding PBS into the various perforated vessels and soaking and washing the antique samples; B), adding goat anti-rabbit IgG (H+L) antibody diluent with green fluorescein markers into the perforated vessels A and B, adding PBS into the perforated vessel C, inoculating the perforated vessels A, B and C in the absence of light, then adding PBS in the various perforated vessels and soaking and washing the antique samples; C), adding buffer glycerin into the perforated vessels A, B and C and sealing slices; D), observing and detecting the perforated vessels A, B and C under laser confocal microscopes. The method has the advantages of high sensitivity, simplicity in operation, low cost, visual results and easiness in analysis.

Description

technical field [0001] The invention relates to the technical field of cultural relic detection, in particular to a detection method for detecting ancient woolen fabrics by using immunofluorescence. Background technique [0002] Wool fabric is the main textile raw material in the ancient northern region and is a precious heritage of China. However, due to the environmental factors in the northern region and the nature of wool protein fibers, most of the decayed cultural relics have been turned into traces. How to use scientific means to identify wool has become an urgent need. Commonly used detection methods are greatly affected by samples, impurities, etc., and the accuracy of the results is not high, so a simpler and more intuitive scientific method is urgently needed. [0003] The Chinese patent with the application number 201010577180.1 discloses a method for analyzing the content of wool fiber, cashmere and wool blended fiber by physical method, which uses fiber photog...
