20140350225 | ANTI-BFGF HUMANIZED DOUBLE-STRANDED ANTIBODY WITH STABLE DISULFIDE BOND, PREPARATION METHOD AND APPLICATION THEREOF - Disclosed are an anti-bFGF humanized double-stranded antibody with stable disulfide bond, the preparation method and the applications thereof. The amino acid sequence of the anti-bFGF humanized ds-Diabody is shown in SEQ ID NO. 1. The nucleotide sequence of gene encoding the anti-bFGF humanized ds-Diabody is shown in SEQ ID NO. 2. By site-directed mutation, two cysteine residues are introduced into each single-stranded antibody, thus introducing the disulfide bond and form ds-Diabody. It is shown by experiments that the obtained ds-Diabody has the following advantages: enhanced stability; better affinity when binding to the specific antigen bFGF; moderate relative molecular weight, good tumor targeting, more powerful in tumor tissue penetration, and higher blood clearance rate, showing a broad application prospects in the clinic diagnosis and tumor therapy. | 11-27-2014 |

20160116317 | ULTRASONIC FLOW TUBE, ULTRASONIC FLOW TUBE ASSEMBLY, ULTRASONIC FLOW SENSOR AND ULTRASONIC FLOW METER - The present disclosure discloses an ultrasonic flow tube. The ultrasonic flow tube includes a water inlet, a water outlet, a sound channel, a first mounting hole for fixing a first ultrasonic transducer, and a second mounting hole for fixing a second ultrasonic transducer. The water inlet defines a first fixing room. The water outlet defines a second fixing room. An entrance and an exit are defined at opposite ends of the sound channel. The entrance is equipped with a chamfer which can make the flow more smoothly and restrain turbulent flow. An installation groove for installing a seal ring is defined at an external sidewall of the ultrasonic flow tube. The seal ring is configured to seal the ultrasonic flow tube and a peripheral structure of the ultrasonic flow tube. The ultrasonic flow tube is made of plastic or ceramic. | 04-28-2016 |
