| Protein Construction |
|
||||
| Purity | > 95% as determined by Bis-Tris PAGE | ||||
| Endotoxin Level | Less than 1EU per μg by the LAL method. | ||||
| Biological Activity |
Measured by its binding ability in a functional ELISA. Test result was comparable to standard batch. Measured by its ability to cleave the colorimetric peptide substrate, Succinyl-Arg-Pro-Tyr-p-Nitroanilide (Suc-RPY-pNA). Test result was comparable to standard batch. |
||||
| Expression System | HEK293 | ||||
| Theoretical Molecular Weight | 27.93 kDa | ||||
| Apparent Molecular Weight | Due to glycosylation, the protein migrates to 32-38 kDa based on Bis-Tris PAGE result. | ||||
| Formulation | Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). | ||||
| 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 & Stability | Upon receiving, the product remains stable for 6 months at -20℃ or below. Upon reconstitution, the product should be stable for 3 months at -80℃. Avoid repeated freeze-thaw cycles. |
The purity of Kallikrein 3/PSA (pro form), His, Human is greater than 95% as determined by SEC-HPLC. »
Kallikrein 3/PSA (pro form), His, Human on Bis-Tris PAGE under reduced condition. The purity is greater than 95%. »
| Target Background | Kallikrein-related peptidase 3 (KLK3), also known as prostate-specific antigen (PSA), is the most useful biomarker for prostate cancer (PCa). KLK3 is suggested to play a role in regulating cancer growth through anti-angiogenic activity in vivo and in vitro. |
| Synonyms | PSA; Kallikrein 3; Kallikrein-3; P-30 antigen; Semenogelase; KLK3; APS |
