Simple method for analysis of apolipoproteins in high density lipoproteins by high performance liquid chromatography.

abstract：:PTF/SNAPc is a multisubunit complex which specifically recognizes the PSEs of small nuclear RNA genes and activates transcription by RNA polymerase II or III. Here we describe the isolation and characterization of genomic clones encoding the human PTFgamma/SNAP43 gene. The gene spans approximately 29 kilobases, and is...
