226 results about "Salbutamol" patented technology

Albuterol (also known as salbutamol) is used to treat wheezing and shortness of breath caused by breathing problems (e.g., asthma, chronic obstructive pulmonary disease).

Clenobuterol hydrochloride, salbutamol and paylean three joint inspection card and method for processing detecting sample

The invention relates to a clenobuterol hydrochloride, salbutamol and paylean three joint inspection card and a method for processing a detecting sample, and belongs to the technical field of detection of a beta-receptor stimulating agent, wherein a test strip is arranged inside a shell of the three joint inspection card, and the clenobuterol hydrochloride, salbutamol and paylean three joint inspection card is formed by the adhesion of a sample gasket, a colloidal gold membrane, a cellulose nitrate membrane and a water absorbing membrane to a bearing backboard in turn; the colloidal gold membrane is a glass fiber membrane of a colloidal gold marker containing a clenobuterol hydrochloride antibody, a salbutamol antibody and a paylean antibody; three detection strips are arranged on the cellulose nitrate membrane and contain clenobuterol hydrochloride protein conjugate, salbutamol protein conjugate and paylean protein conjugate respectively; and a quality control strip containing an anti-rabbit antibody or an anti-mouse antibody is arranged. The clenobuterol hydrochloride, salbutamol and paylean three joint inspection card has the advantages of simultaneously detecting the clenobuterol hydrochloride, the salbutamol and the paylean in urine or feed, animal tissue, meat and liver. The inspection card is easy to prepare and quick and convenient to use, saves the detection cost, and has accurate result.

A group of oligonucleotide aptamers for identifying clenbuterol hydrochloride, salbutamol and ractopamine with high specificity

The invention provides a group of oligonucleotide aptamers Apt-1, Apt-2 and Apt-3 which are capable of simultaneously identifying clenbuterol hydrochloride and salbutamol, an oligonucleotide aptamer CLB-2 which is capable of identifying the clenbuterol hydrochloride with high specificity, an oligonucleotide aptamer SAL-5 which is capable of identifying the salbutamol with high specificity and two oligonucleotide aptamers RAC-5 and RAC-6 which are capable of identifying ractopamine with high specificity. Through an SELEX (Systematic Evolution of Ligands by Exponential Enrichment) technology based on Fe3O4 magnetic nanoparticle separation, a random oligonucleotide library is immobilized on avidin-enveloped magnetic nanoparticles by virtue of a complementary chain of a biotinylation marker, and the oligonucleotide aptamers, which are high in specific affinity, are finally obtained by conducting screening by 16 turns. The aptamers are broad in application prospect; and the aptamers, by virtue of marker function genes or fluorescent dyes, are applicable to detection of the clenbuterol hydrochloride, the salbutamol and the ractopamine in food; therefore, a new choice is provided for existing detection methods which depend on antibodies.
