摘要:
An isolated polypeptide includes the amino acid sequence shown in SEQ. ID No. 13 and an isolated nucleic acid encoding the polypeptide, such as an isolated nucleic acid including the nucleic acid sequence shown in SEQ. ID No. 17. The isolated polypeptide includes two heparin binding polypeptides connected in tandem and the isolated nucleic acid encodes these. The polypeptide and nucleic acid sequences can improve retroviral vector mediated gene transfer efficiency into target cells.

摘要:
Polypeptides are provided which have a calpain inhibitory activity. The polypeptides have an activity like that of natural human calpastatin but are significantly shorter in length than natural human calpastatin. The polypeptides are suited for synthetic manufacture.
摘要:
The present invention provides a method for increasing the efficiency of gene transfer into target cells with a retrovirus. The transduction is affected by infecting target cells with a retrovirus in the presence of a mixture of a functional material having a retrovirus binding domain, and a second functional material having target cell binding domain. The target cells may be selected from the group of unintentional hematopoietic progenitor cells and erythrocyte precursor, specifically pluripotent stem cells or embryopalstic stem cells.
摘要:
The present invention provides a kit to carry out retrovirus-mediated gene transfer into target cells. The kit contains a functional material bearing a retrovirus binding domain, another functional material bearing a target cell binding domain, an artificial substrate for incubating the retrovirus contacted with the target cells, and a target cell growth factor for pre-stimulating target cells to spur them along the cell cycle. The kit of the invention may further comprise a recombinant retroviral vector, necessary buffers, and the like.

摘要:
A method is disclosed for increasing the efficiency of retroviral mediated gene transfer into viable target cells, which comprises transducing the target cells by infecting the target cells with a replication defective recombinant retrovirus that infects the target cells in an aqueous medium in the presence of (a) a mixture of an effective amount of a first functional material having a retrovirus binding domain that binds said retrovirus, and an effective amount of a second functional material having a target cell binding domain that binds said target cell, or (b) an effective amount of a bifunctional material having both a retroviral binding domain which does not contain the heparin binding domain derived from human fibronectin, and a target cell binding domain, wherein the bifunctional material has a retrovirus binding domain that binds to said retrovirus and a target cell binding domain that binds to the target cell.
