Sodium fusidate crystallization method

Номер: CN103012536A
Принадлежит:

The invention provides a sodium fusidate crystallization method which comprises the following steps: a, preparing a sodium fusidate solution by taking a acetone water solution as solvent; b, heating the sodium fusidate solution, feeding acetone while stirring, reducing the feeding rate when the sodium fusidate solution is turbid, and standing for crystallization after the feeding operation is finished; and performing solid-liquid separation, leaching the obtained solids with acetone, and then drying to obtain sodium fusidate crystals. According to the invention, the method is simple to operate and low in cost; and the sodium fusidate crystals prepared by the method are stable in crystal form and favorable in flowability.

In-vitro detection method of allergen in food

Номер: CN103257237A
Принадлежит:

The invention relates to an in-vitro detection method of allergen in food. The invitro detection method comprises the steps of: 1) establishing an IgE (Immunoglobulin E) hyperresponsiveness food allergic animal model based on an allergen immuned mouse; and 2) exciting a sensitization RBL-2H3 cell, an allergen or a rat anti-mouse IgE antibody, and detecting the release rate of beta-hexosaminidase. The invitro detection method provided by the invention is low in detection cost and high in detection sensitivity and specificity, can be used for accurately reflecting the IgE mediated anaphylactoid capability induced by the allergen and evaluating the sensitization of food raw materials and various processed foods, so as to enable the risk of food allergies to be radically reduced.
