The cellular protein p32 was isolated originally as a protein tightly associated with the essential splicing factor ASF/SF2 during its purification from HeLa cells. ASF/SF2 is a member of the SR family of splicing factors, which stimulate constitutive splicing and regulate alternative RNA splicing in a positive or negative fashion, depending on where on the(More)
SR proteins are a family of essential splicing factors required for early recognition of splice sites during spliceosome assembly. They also function as alternative RNA splicing factors when overexpressed in vivo or added in excess to extracts in vitro. SR proteins are highly phosphorylated in vivo, a modification that is required for their function in(More)
Many syndromes have a large number of differential diagnoses, a situation which calls for multiplex diagnostic systems. Myalgic encephalomyelitis (ME), also named chronic fatigue syndrome (CFS), is a common disease of unknown etiology. A mouse retrovirus, xenotropic murine leukemia-related virus (XMRV), was found in ME/CFS patients and blood donors, but(More)
Diagnosis of infectious diseases often requires demonstration of antibodies to the microbe (serology). A large set of antigens, covering viruses, bacteria, fungi and parasites may be needed. Recombinant proteins have a prime role in serological tests. Suspension arrays offer high throughput for simultaneous measurement of many different antibodies. We here(More)
The cellular protein p32 is a multifunctional protein, which has been shown to interact with a large number of cellular and viral proteins and to regulate several important activities like transcription and RNA splicing. We have previously shown that p32 regulates RNA splicing by binding and inhibiting the essential SR protein ASF/SF2. To determine whether(More)
In contrast to ordinary PCRs, which have a limited multiplex capacity and often return false-negative results due to target variation or inhibition, our new detection strategy, VOCMA (variation-tolerant capture multiplex assay), allows variation-tolerant, target-specific capture and detection of many nucleic acids in one test. Here we demonstrate the use of(More)
