20140138703 | Optoelectronic Semiconductor Body and Method for Producing an Optoelectronic Semiconductor Body - An optoelectronic semiconductor body has a substrate that includes a strained layer that is applied to the substrate in a first epitaxy step. The strained layer includes at least one recess formed vertically in the strained layer. In a second epitaxy step, a further layer applied to the strained layer. The further layer fills the at least one recess and covers the strained layer at least in some areas. | 05-22-2014 |

20130030157 | Rodent Combinatorial Antibody Libraries - The present invention provides synthetic rodent antibody libraries, such as mouse or rat antibody libraries, as well as polypeptides, nucleic acids, vectors, host cells and methods used in conjunction with these libraries. The present invention also provides antibodies isolated from such libraries and variants of such antibodies. | 01-31-2013 |
20140186350 | COMPOSITIONS AND METHODS FOR LONG ACTING MOLECULES - The invention relates, in part, to compositions and methods that utilize a peptide tag that binds to hemagglutanin (HA). The HA tag can be linked to a molecule such as a protein or nucleic acid which, when administered to the eye, results in an increase in ocular half-life and/or mean residence time, and or a decrease in ocular clearance of the protein or nucleic acid. The invention also encompasses methods for treating ocular disease, including retinal vascular disease, by administering a protein or nucleic acid linked to an HA peptide tag. | 07-03-2014 |

20110036702 | PROCESS FOR THE RECTIFICATION OF MIXTURES OF HIGH-BOILING AIR- AND/OR TEMPERATURE-SENSITIVE USEFUL PRODUCTS - According to the invention, a process for the rectification of mixtures of high-boiling air- and/or temperature-sensitive substances which require a high separation efficiency is proposed, in particular a process for the working-up of a VE- or VEA-containing product stream. The process is characterized in particular in that, in a first purification stage, low-boiling products and unspecified isomers of the useful product are separated from the product stream virtually without loss of useful product and that, in a second purification stage, the useful product is removed in a stream having a purity of >97% by weight and a further stream having a purity of >92% by weight. A preferred embodiment of the process serves for working up VEA, in which the loss of useful product in the first purification stage is less than 5%, based on that amount of VEA in the feed which is added to the purification stage per unit time. Furthermore, the first purification stage may comprise a rectification column ( | 02-17-2011 |

20090287002 | Process for the working-up of a vitamin E- and vitamin E-acetate- containing mixture or products stream - The invention relates to a process for the working-up of a vitamin E (VE)- and/or vitamin E acetate (VEA)-containing product stream, which is substantially characterized by purification of a vitamin E-containing product stream, acetylation of at least a part of the purified vitamin E and purification of at least a part of the acetylated vitamin E, the purification of vitamin E and vitamin E acetate preferably being effected by distillation, for example rectification. A preferred process according to the invention is characterized in that a vitamin E-containing product stream is fed to a first rectification column ( | 11-19-2009 |
20120156107 | PROCESS FOR THE WORKING-UP OF A VITAMIN E- AND VITAMIN E-ACETATE-CONTAINING MIXTURE OR PRODUCT STREAM - A rectification column and system for the working-up of a vitamin E (VE)- and/or vitamin E acetate (VEA)-containing product stream includes purification of a vitamin E-containing product stream, acetylation of at least a part of the purified vitamin E and purification of at least a part of the acetylated vitamin E, the purification of vitamin E and vitamin E acetate preferably being effected by distillation, for example rectification. | 06-21-2012 |
