Alternative Name(s): La autoantigen;La ribonucleoprotein;Sjoegren syndrome type B antigen ;SS-B
Relevance: Binds to the 3' poly(U) terminus of nascent RNA polymerase III transcripts, protecting th from exonuclease digestion and facilitating their folding and maturation.
Reference: Ribonucleoprotein SS-B/La belongs to a protein family with consensus sequences for RNA-binding.Chan E.K.L., Sullivan K.F., Tan E.M.Nucleic Acids Res. 17:2233-2244(1989)
Purity: Greater than 90% as determined by SDS-PAGE.
Storage Buffer: Tris-based buffer，50% glycerol
Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
