5994517 Ligands to enhance cellular uptake of biomolecules November 30, 1999
Oligodeoxynucleoside methylphosphonate neoglycopeptide conjugates and related compounds for tissue specific delivery of biologically stable, nonionic oligodeoxynucleoside analogs into cells.
5962237 Method of enriching rare cells October 5, 1999
A method for enriching cancer cells such as prostate cancer cells in a bodily fluid sample is disclosed comprising (a) obtaining the sample comprising cancer cells and non-rare cells; (b) subjecting the sample to multiple density gradient separation comprising a first density gradient
5912339 Oligonucleoside alkyl or arylphosphonate derivatives capable of crosslinking with or cleaving nu June 15, 1999
A composition for inactivating a target nucleic acid which comprises an oligonucleoside alkyl or arylphosphonate analogue which is complementary to the sequence of the target nucleic acid and includes a functional group which reacts with the target nucleic acid to render the target nucle
4757055 Method for selectively controlling unwanted expression or function of foreign nucleic acids in a July 12, 1988
A process for selectively controlling or interfering with the effect or function of foreign nucleic acid in the presence of otherwise normal living cells which comprises determining the base sequence for said nucleic acid and binding the said nucleic acid with an appropriately prepar
4591614 Preparation of oligodeoxyribonucleoside alkyl or arylphosphonates May 27, 1986
Oligonucleoside-3'-alkyl or aryl phosphonates are prepared by condensing (i) a 5'-protected nucleoside 3'-alkyl or aryl phosphonic imidazolide with (ii) a nucleoside or oligomer which is attached through its 3'-position to a polymer support. The process is advantageously carried out in t
4587044 Linkage of proteins to nucleic acids May 6, 1986
A nucleic acid-protein conjugate which is specific with respect to a selected living cell is prepared by linking said nucleic acid to a protein specific to said living cell.
4511713 Process for selectively controlling unwanted expression or function of foreign nucleic acids in April 16, 1985
