摘要:
A method is provided for expressing the proteases dipeptidyl aminopeptidases A and B which are useful for processing precursor proteins. Genes controlling these proteases may be insdrted into appropriate vectors and transformed into cultures. The proteases may either be utilized to process precursor proteins in vivo or may be extracted from cultures and used to process precursor proteins in vitro.
摘要:
A shortened PGK promoter ranging from 165 to 404 base pairs of the Saccharomyces PGK promoter is taught. The promoter is operably linked to heterologous genes and improves the expression thereof relative to the full length PGK promoter.
摘要:
The invention provides methods for detecting target nucleic acid sequences with diagnostic probes including first and second probe regions that are substantially complementary to first and second target regions respectively on a target nucleic acid strand wherein the first probe region is located 5′ to the second probe region. The first probe region is substantially complementary to the first target region, on the target nucleic acid strand, which also includes a second target region, wherein when said first target region is contiguous with the second target region on the target nucleic acid strand, then the first and second probe regions on the diagnostic probe are separated by a spacer region of nucleic acid.
摘要:
The invention provides methods for detecting target nucleic acid sequences with diagnostic primers including priming regions and probe regions which are complementary to target and reference regions respectively on a sample nucleic acid strand wherein the probe region is located 5′ to the priming region which is complementary to a reference nucleic acid sequence which is 3′ to the target nucleic acid sequence on the sample nucleic acid strand wherein when said reference nucleic acid sequence is contiguous with said target nucleic acid sequence on the sample nucleic acid strand then the priming region and probe region on the diagnostic probe are separated by a spacer region of nucleic acid.
