Method for embedding a load based on gel high hydrostatic pressure liquefaction

The invention relates to a method for embedding a load based on gel high hydrostatic pressure liquefaction. Using the phenomenon that the physical gel is liquefied under high pressure, the vacuum-packaged high-methoxyl pectin gel is treated under a pressure of 400-600 MPa for 5-30 min, mixed with the load, and then subjected to a pressure of 400-600 MPa for homogenization treatment for 5 to 30 min. After pressure relief, the liquefied gel is poured into a mold for reshaping, followed by removal of free water and coating treatment. This method combines the advantages of high hydrostatic pressure technology in modification and sterilization. It has mild embedding conditions and wide sources of raw materials to prepare the carrier, which has excellent biocompatibility and biodegradability. It can be widely used for embedding microorganisms, enzymes, proteins and small molecular substances. The loaded gel prepared by the method has high microbial safety, can effectively maintain the activity of the load. The load distribution is uniform, and the load amount is much larger than the traditional adsorption load.

INERT MATRICES FOR QUALITATIVE AND SEMI-QUANTITATIVE SEED AMPLIFICATION ASSAYS
20230084155 · 2023-03-16 · ·

Inert matrices for use with a-synuclein seed amplification assays (“αS-SAA”s) are provided. The inert matrices accurately reflect the absence of misfolded αS protein when used as a negative control, in the form of no, perceptively low, or delayed αS substrate self-aggregation, yet will readily permit aggregation of the αS substrate with seeds when used as a positive control. The inert matrices may be used to screen for αS-SAA reagent competence. The inert matrices may be used to dilute samples taken from peripheral biological matrices. Finally, the inert matrices may be used as a diluent for serial dilutions of αS-SAA samples, to enable semi-quantitative versions of αS-SAAs.
