纯度: > 96 % by SDS-PAGE and HPLC analyses. 

生物活性: Fully biologically active when compared to standard. The ED50 as determined by inhibiting IL-1α-

dependent proliferation of murine D10S cells is less than 40 ng/ml, corresponding to a specific 

activity of > 2.5 × 104

 IU/mg in the presence of 50 pg/ml rHuIL-1α. 

物理性质: Sterile Filtered White lyophilized (freeze-dried) powder. 

成分: Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4. 

内毒素: Less than 1 EU/μg of rHuIL-1RA as determined by LAL method. 

重构: 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 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions. 

储存条件: This lyophilized preparation is stable at 2-8 °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 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C. Avoid repeated freeze/thaw cycles. 

用途: This material is offered by PrimeGene Bio-Tech for research, laboratory or further evaluation purposes. NOT FOR HUMAN US
