ab19321-100ug，Anti-S tag antib

The S tag is a peptide sequence derived from ribonuclease A commonly used in molecular biology for protein purification and detection. This tag has a molecular mass of approximately 2 kDa. Researchers often utilize S tags for their small size which minimizes interference with protein function. The S tag is typically expressed as a fusion with the protein of interest which enables it to be used as a versatile tool in a variety of expression systems./ Biological function summary/ S tags do not independently participate in cellular functions but instead facilitate experimental procedures. When fused to a protein the S tag allows for simple detection and purification using anti-S tag antibodies. This functionality makes it possible to isolate and study the protein of interest without affecting its native activity significantly. While S tags do not form part of any specific complex they interact with complexes like alkaline phosphatase in experimental applications to enhance detection signals./ Pathways/ S tags themselves do not have inherent roles in cellular pathways. However they are used as a tool in studies involving signal transduction or metabolic pathways where their presence aids in tracking or manipulating pathway components. Due to their utility S tags can be connected indirectly to proteins such as ALP (alkaline phosphatase) by enabling pathway mapping in experiments./
