Patents by Inventor Allen R. Zeiger

Allen R. Zeiger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5310894
    Abstract: Methods for solid-state synthesis of polymers, especially polypeptides and polynucleotides, are provided. In accordance with a preferred embodiment, selectively activatable and reactive bonding moieties are covalently bonded to solid supports for polynucleotide and polypeptide syntheses. Products of failed reactions and some side products are caused to react with the selectively activatable and reactive bonding moiety to cause divalent bonding of unwanted products to the solid support. Upon cleavage of the initial situs of covalent bonding to the solid support, desired products are free to be collected while unwanted products remain covalently bonded to the support. Ease of purification of such polymers is a principal object of the present invention. The methods of the invention are amenable to automation and digital control and novel solid supports, activatable, reactive bonding moieties and other compositions are presented.

  • Patent number: 4888279
    Abstract: New immunosorbent enzyme assays are provided employing antibiotic keying agents for binding a molecular species to be detected to a test surface followed by binding of an antibody specific for the species and detection of the antibody-species binding. In accordance with preferred embodiments, soluble peptidoglycan is assayed in a fluid binding it to a test surface with vancomycin, reacting the bound material with a peptidoglycan specific antibody, and measuring the extent of the antibody reaction. Assessment of bodily fluids and fermenation broths for the presence of certain kinds of antibiotics is one object of this invention. Assessment of sera for the presence of antibodies that have specificity for soluble peptidoglycans is another object of this invention. Assessment of bodily states in mammals is another object of the invention.
