FIELD: medicine. ^ SUBSTANCE: invention refers to biotechnology and genetic engineering, namely to a genetically engineered construct pGoatcasGCSF for human granulocyte colony-stimulating factor (GCSF) expression . The offered invention can be used for producing transgenic animals that are human granulocyte colony-stimulating factor producers. It involves creating the genetically engineered construct pGoatcasGCSF of the size 6386 bps, and a specified nucleotide sequence shown in SEQ ID 1. The genetically engineered construct pGoatcasGCSF includes a 5'-regulatory sequence of the goat CSN1S1 asi-casein gene of the size 3387 bps connected with the full-size human GCSF gene of the size 1485 bps, and a 3'-flanking region of the cow gene CSN1S1 of the size 1514 bps. ^ EFFECT: stable effective level of human GCSF expression in milk of the transgenic animals, eliminated possibility of ectopic transgenic expression. ^ 9 dwg, 2 tbl, 6 ex |
