Washing liquid for staphylococcus aureus immunomagnetic beads

Abstract

The invention discloses a washing liquid for staphylococcus aureus immunomagnetic beads. Compared with a conventional washing liquid, through component optimization, the washing liquid has an improvedcleaning effect, effectively reduces the interference of a food matrix and has a specific and persistent bacteria increasing effect, and especially, the bacteria increasing effect on a sample with extremely low target bacteria content is remarkable, so that the detection rate of staphylococcus aureus is improved, and the application of the immunomagnetic beads in reagent detection is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of immunization, in particular to a Staphylococcus aureus immune magnetic bead washing solution. Background technique [0002] Staphylococcus aureus (Staphylococcus aureus) is one of the common food-borne pathogenic microorganisms, which can produce Staphylococcus aureus Enterotoxins (SEs) under appropriate conditions, which is the most important pathogenic factor. Staphylococcus aureus is widely distributed, and can be found in external environments such as air, water, humans and animals and their excreta; internal environments such as human and animal body surfaces, mucous membranes, respiratory tract, nasopharynx and intestinal tract are also distributed. 30%-50% of healthy people are carriers of Staphylococcus aureus, so Staphylococcus aureus is everywhere. [0003] In recent years, with the emergence of new detection technologies, especially molecular detection products, the sensitivity has been impro...

Problems solved by technology

However, the conventional immunomagnetic bead washing solution does not have a good effect in practical applications. When enriching complex food samples such as minced meat, a large amount of immunomagnetic beads will be lost, thereby reducing the detection rate of target bacteria.
