  • Publication number: 20190330267
    Abstract: The present invention relates to improved processes for purifying polypeptides of interest by increasing the amount of a polypeptide of interest bound to an ion-exchange matrix relative to the amount of one or more impurities bound to the ion-exchange matrix. This effect is achieved by adding a chemical compound in the process which by also binding to the ion-exchange matrix due to a change that is opposite to the change of the ion-exchange matrix, reduces the binding of impurities more than the binding of the polypeptide of interest.

  • Patent number: 9782306
    Abstract: A secondary internal topsheet and leg wrap structure is provided in a disposable absorbent garment such as a diaper or training pants. The leg wrap structure has a base layer, a top layer, and an elastic construction disposed inbetween. The elastic construction includes a plurality of spaced apart elastic elements that are aligned in a generally in generally parallel relation. The leg wrap structure and secondary topsheet provides for the efficient formation of a reservoir and a plurality of fluid dams each capable of capturing a quantity of fluid to minimize the occurrence of fluid leaks from the absorbent article. Methods of forming such absorbent articles are disclosed.

  • Patent number: 9175279
    Abstract: The present invention relates generally to a method of purifying Factor VII and/or Factor VIIa from a solution containing either or both proteins, the method comprising: diluting the solution containing Factor VII and/or Factor VIIa in a loading buffer; adding the diluted solution from step (i) to a multi-modal anion exchange resinunder conditions selected such that Factor VII and/or Factor VIIa is bound to the resin; optionally washing the resin with a wash buffer; adding an elution buffer to the resin under conditions selected such that Factor VII and/or Factor VIIa is eluted from the resin; and recovering the eluted recombinant Factor VII and/or Factor VIIa; wherein the loading buffer, the optional wash buffer and the elution buffer each comprise about 35 mM or less of calcium ions.

  • Patent number: 8784397
    Abstract: A leg wrap structure is provided in a disposable absorbent garment such as a diaper or training pants. The leg wrap structure has a base layer, a top layer, and an elastic construction disposed therebetween. The elastic construction includes a plurality of spaced apart (e.g. generally equally spaced apart) elastic elements (e.g. strands or threads) that are aligned in a generally in generally parallel relation. Further, the top and base layers define a region of inelasticity. The leg wrap structure provides for the efficient formation of a reservoir and a plurality of fluid dams each capable of capturing a quantity of fluid to minimize the occurrence of fluid leaks from the absorbent article. Methods of forming such absorbent articles are disclosed.

  • Publication number: 20060105904
    Abstract: The invention relates to a molecular sieve catalyst composition, to a method of making or forming the molecular sieve catalyst composition, and to a conversion process using the catalyst composition. In particular, the invention is directed to a catalyst composition comprising a molecular sieve having a framework including at least [AlO4] and [PO4] tetrahedral units, at least one of a binder and a matrix material and at least one phosphorus compound separate from said molecular sieve wherein, after calcination at 760° C. for 3 hours, said catalyst composition has a microporous surface area in excess of 20% of the microporous surface area of said molecular sieve after calcination at 650° C. in nitrogen for 2 hours. The catalyst composition is particularly useful in a conversion process for producing olefin(s), preferably ethylene and/or propylene, from a feedstock, preferably an oxygenate containing feedstock.
