Abstract: An isolated IgG antibody includes two identical heavy chains each having a hinge region with an amino acid sequence containing an additional cysteine upstream of the two cysteines in the CPPCP sequence of a native IgG hinge region, and a CH1 domain containing a cysteine at the position of 142 according to the IMGT numbering scheme. ADCs based on the antibody having this architecture are also provided.

Abstract: An integrated acoustic detection and rock direct tensile test machine includes a support frame. A top of the support frame is provided with a top plate and a bearing plate is provided above the top plate. The bearing plate is provided with force transferring rods, lower ends of which are provided with a tensile base. A top of the tensile base is provided with a lower clamp holder and a bottom of the top plate is provided with an upper clamp holder. An upper channel is provided inside the upper clamp holder. The upper channel is provided with an acoustic transmitting probe. A lower channel is provided inside the lower clamp holder. One end of the lower channel is communicated with the outside, the other end is provided with an acoustic receiving probe. The lower channel extends to a bottom of a clamping chamber of the lower clamp holder.

Abstract: A clamping triaxial seepage and acoustic coupling rock tensile testing machine includes a sample and a scaffold-type tensile testing device. The scaffold-type tensile testing device has an upper chuck and a lower chuck. The upper chuck has an acoustic transmitting channel, one end of which communicating with the outside, and the other end of which having an acoustic transmitting probe. The lower chuck has an acoustic receiving channel, one end of which communicating with the outside, and the other end having acoustic receiving probe. An upper end face of the sample has with a seepage outflow hole while the upper chuck has a seepage outflow channel connected with the seepage outflow hole. A lower end face of the sample has a seepage inflow hole while the lower chuck has a seepage entry channel is connected with the seepage inflow hole.

Abstract: A composite fertilizer containing magnesium ammonium phosphate and polyglutamic acid. A weight ratio of the polyglutamic acid to the magnesium ammonium phosphate is 1:100 to 10000, preferably 1:200 to 8000. An experimental result indicates that the composite fertilizer can well regulate the growth of crops, improve the disease resistance and stress tolerance, promote the healthy effect of the crops, and increase the yield of the crops.

Abstract: The present invention discloses a plant growth regulator. The effective ingredients of the plant growth regulator comprise active components A and B, wherein the active component A is thidiazuron, and the active component B is amino-oligosaccharin. Also provided are a preparation method and use of the composition. Experimental results indicate that the composition of the present invention is effective in regulating the growth, increasing the disease and stress resistance, promoting the health and increasing the yield and quality of crops.
