C22orf39 Antibody, HRP conjugated

What is C22orf39 and why is it studied in research?

C22orf39 (Chromosome 22 Open Reading Frame 39) is also known as UPF0545 protein C22orf39, a protein encoded by a gene located on chromosome 22. The protein has been designated with UniProt accession number Q6P5X5 . While currently classified as an open reading frame with limited functional characterization, researchers study this protein to elucidate its biological role in human cellular processes. The HRP-conjugated antibodies targeting C22orf39 enable various detection methods in research settings aiming to understand protein expression patterns, localization, and potential functions in normal and pathological conditions.

What is the difference between unconjugated and HRP-conjugated C22orf39 antibodies?

Unconjugated C22orf39 antibodies consist solely of the immunoglobulin molecules that specifically recognize and bind to C22orf39 protein.
