Name : Human SP17 Protein
Product Source :
Recombinant Human SP17 Protein is expressed from E.coli with His tag at the N-Terminus. It contains Met1-Lys151.[Accession | Q15506]
Molecular Weight :
The protein has a predicted MW of 18.50 kDa. The protein migrates to 20-28 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
Formulation :
Lyophilized from 0.22μm filtered solution in 20mM Tris, 150mM NaCL (pH 8.0). Normally 8% trehalose 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 SP17 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
Background :
Sperm protein 17 (Sp17) is a highly conserved mammalian protein characterized in rabbit, mouse, monkey, baboon, macaque, human testis and spermatozoa. mRNA encoding Sp17 has been detected in a range of murine and human somatic tissues. It was also recognized in two myeloma cell lines and in neoplastic cells from patients with multiple myeloma and ovarian carcinoma.
Synonyms :
CT22; Sp17-1; Sperm protein 17; SPA17;
