Name : Human C-Reactive Protein /CRP Protein
Product Source :
Recombinant Human C-Reactive Protein /CRP Protein is expressed from HEK293 with His tag at the C-terminus. It contains Gln19-Pro224.[Accession | NP_000558.2]
Molecular Weight :
The protein has a predicted MW of 24.1 kDa. Due to glycosylation, the protein migrates to 25-27 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22 μm filtered solution in 20mM Tris, 300mM NaCl (pH 8.0). Normally 8% trehalose / 8% mannitol is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human CRP on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human CRP is greater than 95% as determined by SEC-HPLC.
Background :
C-reactive protein (CRP) is a polypeptide molecule belonging to the family of pentraxins. CRP is synthesized primarily by the liver in response to certain pro-inflammatory cytokines. It plays an important role in innate immunity, opsonization by its properties, complement activation and immunoglobulins receptor binding. CRP is a protein of the acute systemic inflammation and is, therefore, a prime marker of inflammation.The CRP is quantified by immunonephelometry or immunoturbidimetry.
Synonyms :
C-reactive protein; CRP; PTX1; MGC88244; pentraxin 1; PTX1MGC149895
