|Product Overview :
||Recombinant Corn Hageman factor inhibitor was expressed inCorn. MW=12.5 KDa.
||To begin the purification process, CTI is extracted from the kernels of fresh sweet corn into a physiologic buffer. The extract is then de-fatted using acetone, and the protein is further purified by employing gel filtration and ion-exchange chromatography. The final CTI preparation appears as a single band by SDS-PAGE analyses under both reducing and non-reducing conditions. Preparations of CTI are tested for the ability to prolong the aPTT assay without affecting the PT assay. The specific activity of each lot of CTI is determined, and one unit is defined as the amount of CTI required to double the aPTT of normal human plasma.
||0.02 M Tris-HCl; 0.15 M NaCI; pH 7.4.
|Specific activity :
||34.2 U/mg (One inhibitory unit will double the aPTT clot time of 1 ml of normal human plasma).
|Shipping Information :
