A protein binding to a minor-group human rhinovirus (HRV2) was purified from HeLa cell culture supernatant. The amino acid sequences of tryptic peptides showed identity with the human low density lipoprotein (LDL) receptor (LDLR). LDL and HRV2 mutually competed for binding sites on human fibroblasts. Cells down-regulated for LDLR expression yielded much(More)
A complementary DNA (cDNA) of 2559 bp which encode all 674 amino acids of mouse protein kinase C-delta (PKC-delta) has been isolated from a cDNA library prepared from ABPL-2, a mouse myeloid tumor. The library was screened with a partial PKC-delta cDNA clone that had been created by polymerase chain reaction (PCR) amplification of ABPL-2 RNA using primers(More)
Monoclonal antibodies have been produced against two functionally different domains present in two cellobiohydrolases from Trichoderma reesei (CBH I and CBH II). Four groups of antibodies were obtained, which specifically recognized (Western blotting, ELISA) (a) the core protein within CBH I, (b) the core protein within CBH II, (c) the BA region of CBH I,(More)
An endo beta-1,4-glucanase (EC 3.2.1.4, 1.4-(1,3;1,4)-beta-D-glucan 4 glucanhydrolase) was purified to apparent homogeneity from culture filtrates of Trichoderma reesei QM 9414. Identity of the protein with endoglucanase I (EG I) was examined by subjecting CNBr fragments of the protein to analysis by plasma desorption mass spectrometry. Seven(More)
The RalA and RalB proteins comprise a distinct family of small GTPases [1]. Ral-specific guanine-nucleotide exchange factors such as RalGDS, Rlf and RGL interact with activated Ras and cooperate with Ras in the transformation of murine fibroblasts [2-5]. Thus, the interaction of RalGDS with Ras and the subsequent activation of Ral are thought to constitute(More)
Using a combination of raf and myc oncogenes co-expressed by the recombinant retrovirus J-2 we have generated and characterized a cell line which very efficiently supports the growth of B-cells and B-cell hybridomas. Murine spleen cells were cultured under in vitro immunization conditions favoring the short term proliferation of splenic B lymphocytes and(More)
Soluble rhinovirus minor group binding activity was found to be shed into the medium upon incubation of HeLa cells at 37 degrees C. Although substantial amounts of this protein were released, no decrease of virus binding to the cell surface was seen. When the membrane-associated receptor was stripped from the cells with trypsin, virus binding was rapidly(More)
INTRODUCTION Many policy makers and researchers consider knowledge transfer between academia and industry as one of the most promising measures to strengthen economic development. The idea of linking academia and industry is not new. Back in 1910 research universities were established, which strongly emphasized industry-related research as part of their(More)
