Description
Accession
P07288
Source
Optimized DNA sequence encoding Human Prostate specific antigen(ALA18 - PRO261) preprotein including a C-terminal His tag was expressed in HEK293 cells.
Molecular weight
Recombinant Human Prostate specific antigen(PSA) is a protein consisting of 250 amino acid residue subunits,due to glycosylation migrates as an approximately as 36kDa band protein on reduced SDS-PAGE.
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
The activity was tested by the ability to cleave a fluorogenic substrate Suc-RPY-pNA .The specific activity was measured to be 60 pmole/ug/min
Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Presentation
Recombinant Prostate specific antigen (PSA) is lyophilized from 0.2 μm filtered PBS solution, pH7.2 , 5% Trehalose.
Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage
Recombinant Prostate specific antigen (PSA) can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to-70°Cfor twelve months. Avoid repeated freeze/thaw cycles.
