Recombinant Human PTN(pleiotrophin),重组人多效生长因子（PTN）的产品活性：
Purity: > 96 % by SDS­PAGE and HPLC analyses. 
Biological Activity: Fully biologically active when compared to standard. The biological activity was measured by its 
ability to enhance neurite outgrowth of E16­E18 rat embryonic cortical neurons, when neurons were 
plated on 96 well culture plates that had been pre­coated with 100 µl/well of a solution of 5­10 µg/ml 
rHuPTN. 
Physical Appearance: Sterile Filtered White lyophilized (freeze­dried) powder. 
Formulation: Lyophilized from a 0.2 m filtered solution in PBS, pH 7.4. 
Endotoxin: Less than 0.1 EU/ug of rHuPTN as determined by LAL method. 

Recombinant Human PTN(pleiotrophin),重组人多效生长因子（PTN）的储存：
Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the 
bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a 
concentration of 0.1­1.0 mg/mL. Stock solutions should be apportioned into working aliquots and 
stored at ≤ ­20 °C. Further dilutions should be made in appropriate buffered solutions. 
Storage: This lyophilized preparation is stable at 2­8 °C, but should be kept at ­20 °C for long term storage, 
preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2­8 °C. For 
maximal stability, apportion the reconstituted preparation into working aliquots and store at ­20 °C to 
­70 °C. Avoid repeated freeze/thaw cycles.
