Signal Recognition Particle Recombinant Protein | SRP54 recombinant protein
Recombinant Human Signal Recognition Particle 54kDa
Immunological Tests: Standard ELISA test (checkerboard analysis of positive/negative sera panels); immunodot test with positive/negative sera panels.
Introduction: SRP54 is a 54-kDa subunit of the signal recognition particle (SRP), a cytoplasmic ribonucleoprotein complex which leads the translocation of newly synthesized secretory proteins from the polysome to the endoplasmic reticulum. SRP is composed of six polypeptides and a tRNA-like molecule known as 7SL RNA. SRP54 is a GTP-binding protein that directly binds the signal sequences of nascent secretory and membrane proteins. Anti-SRP autoantibodies take place in patients with an autoimmune chronic muscle inflammation called polymyositis. These auto-antibodies predominantly recognize the SRP54 subunit and in addition are able to immunoprecipitate several of the SRP subunits and the RNA component. Nearly 5% of myositis patients are positive for anti-SRP autoantibodies, increasing to 18% in the subgroup of Jo-1 autoantibody-negative patients. The classic 'anti-SRP syndrome' is a severe form of polymyositis in which the myositic inflammation is acute and aggressive onset, with common myalgias and cardiac involvement. Normally there is a poor reaction to therapy with a 5-year survival rate of about 25%.

AAA Biotech's Signal Recognition Particle can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), ELISA (EIA), Immunodot. Western blot with myositis sera or monoclonal anti-hexa-His-tag antibody. Immunological Tests: Standard ELISA test (checkerboard analysis of positive/negative sera panels); immunodot test with positive/negative sera panels. Researchers should empirically determine the suitability of the SRP54 srp54 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Signal Recognition Particle, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
