Abstract:
The present invention relates to a technique for producing in vivo fertilized eggs in mammals and, more specifically, to a technique for producing in vivo fertilized eggs, which induces super ovulation by temporary undernutrition of mammals. According to the present invention, the number of transferable embryos to impotent cows in Hanwoo (Korean beef) can be increased. Therefore, the labor and costs for super ovulation of impotent cows and collection of fertilized eggs, and feed costs can be reduced. Also, high performance cow varieties with high meat quality can be improved. [Reference numerals] (AA) Spawning
Abstract:
PURPOSE: A transgenic chicken and a method for producing the same are provided to ensure anti-viral ability and to be used as a model animal for preventing viral diseases. CONSTITUTION: A vector for transformation contains a promoter which is operable in birds and a 3D8 scFv gene which is operatively linked to the promoter. The promoter is a chicken beta-actin gene promoter. The 3D8 scFv gene further contains a reporter gene. The reporter gene is HA-tag. A method for producing a transgenic chicken comprises: a step of preparing the vector; a step of transducing the vector to chicken fertilized eggs; and a step of hatching the fertilized eggs.
Abstract:
PURPOSE: A mutant human G-CSF with increased biological activity is provided to ensure superior biological activity and excellent economic effect with low dosage. CONSTITUTION: A mutant human G-CSF has amino acid modification by N-glycosylateion by formation of Asn-X-Ser/Thr(N-X-S/T) sequence in an amino acid residues: T1-P10 (T1-P-L-Q-P-A-S-S-L-P10); K40-Q70 (K40-L-C-H-P-E-E-L-V-L-L-G-H-S-L-G-I-P-W-A-P-L-S-S-C-P-S-Q-A-L-Q70); or L124-S142 (L124-G-M-A-P-A-L-Q-P-T-Q-G-A-M-P-A-F-A-S142). A pharmaceutical composition contains the mutant human G-CSF.
Abstract:
방제작업기는중앙프레임부, 제1 및제2 살포프레임부들및 장애물감지회피부를포함한다. 중앙프레임부는승용관리기의중앙에배치되며, 중앙으로부터수평방향으로연장되어형성된다. 제1 및제2 살포프레임부들은중앙프레임부의양측에각각연결되고, 수평방향으로접이가능하며각각방제액을살포하기위한복수의살포유닛들을갖는적어도 2개이상의살포윙들을포함한다. 장애물감지회피부는제1 살포프레임부의살포윙들및 제2 살포프레임부의살포윙들중 적어도하나에배치되며, 주행부의주행방향의전방에위치하는장애물을감지하는센서를포함하고, 장애물이감지된경우장애물을감지한센서를갖는감지살포윙보다중앙에서멀리배치된하위살포윙을수평방향으로접는다. 이에따라, 전방에배치된장애물을용이하고확실하게회피할수 있고, 장애물회피방식을보다간단하고용이하게효율적으로구성할수 있다.
