  • Patent number: 10716887
    Abstract: Provided is a filtration module for separating plasma from blood comprising a feeder channel lid, a feeder channel defined by a feeder channel laminating layer having a thickness of less than 5 mil, a filter element in fluid communication with the feeder channel and having a pore size of less than 2 microns and low surface area, and a filtrate take-off port having a dead volume of less than 10 ?L. Also provided are methods for filtering a blood sample comprising supplying the blood sample to a feeder channel of a filtration module and drawing the blood sample over a filter element of the filtration module in a single pass process configuration to provide a retentate and a plasma filtrate.

  • Publication number: 20080260740
    Abstract: Particular anti-LFL2 antibody compositions are provided herein. These antibodies may be used for diagnosis, prognosis, therapeutic monitoring and treatment of cancer, especially breast cancer, head/neck cancer, lung cancer, ovarian cancer, stomach cancer and pancreatic cancer. Furthermore, anti-LFL2 antibodies are provided herein which target the LFL2 stump remaining after proteolytic cleavage of the extracellular domain of LFL2. Additionally, anti-LFL2 antibodies are provided herein which target the stroma surrounding cancer tumors, wherein said stroma-targeting anti-LFL2 antibodies disrupt the integrity of the stroma surrounding the cancer tumor, and also make the stroma more permeable to chemotherapeutic agents and other molecular drug agents that target tumor cells.
