  • Publication number: 20170022248
    Abstract: The present invention relates to a method for purifying an immunoglobulin, and more particularly, to a method for purifying an immunoglobulin, which comprises: dialyzing and concentrating an immunoglobulin-containing plasma protein fraction II paste; removing thrombotic substances from the dialyzed and concentrated fraction by a purification process using ceramic cation exchange resin; and performing elution while maintaining salt concentration at a constant level to maintain the polymer content of the immunoglobulin at a low level. When the immunoglobulin purification method according to the present invention is used, the efficiency with which impurities and thrombotic substances are removed can be increased and the polymer content of the immunoglobulin can be maintained, and thus a stable immunoglobulin with improved quality can be produced.

  • Publication number: 20160211502
    Abstract: A pouch battery having improved overcharging safety includes a CID interrupting an electrical connection between an electrode assembly and a lead tab when the pouch is expanded. When the pouch is expanded, the CID discharges gas generated inside the pouch to the outside, and at the time of overcharging a secondary battery, the CID interrupts a flow of current introduced into the secondary battery and discharges the gas generated due to the overcharging to the outside of the pouch, thereby reducing an ignition risk and improving the overcharging safety.
