摘要:
The invention provides a plurality of peptides (and immunologically functional variants thereof) which are immunogenic epitopes recognized by CD8+ class I MHC restricted cytotoxic T-lymphocytes of patients harboring latent human cytomegalovirus (HCMV) infection. The peptides are capable of activating CTLs and CTLps in the absence of active viral replication, and thus are useful for eliciting a cellular immune response against HCMV by normal and immunodeficient subjects. Peptide and lipopeptide vaccines, with and without adjuvants, also are disclosed. Cellular vaccines comprising the peptides form a further embodiment of this invention.
摘要:
An antigen binding protein construct or "minibody" which includes the VL and VH domains of a native antibody fused to the hinge region and CH3 domain of the immunoglobulin molecule is described. Minibodies are small versions of whole antibodies which encode in a single chain the essential elements of a whole antibody. Minibodies are expressed by host cells transformed with minibody genes.
摘要:
A method for the ex-vivo expansion of mammalian hematopoietic stem cells (HSC) comprises culturing isolated HSC in a culture system comprising a culture medium in the presence of a stem cell expansion promoting factor (SCEPF) which may be obtained by culturing murine stromal cells in the presence of an amount of leukemia inhibitory factor (LIF) sufficient to stimulate the production and secretion of said expansion promoting factor.
摘要:
A method for C-Terminal degradation of peptides and proteins involves forming a thiohydantoin derivative of the C-Terminal amino acid and then cleaving the derivatized amino acid by reaction with methoxide or methiolate ions.
摘要:
Administration of pregnenolone or pregnenolone sulfate to enhance memory and improve the quality of life in mammals, including humans, is disclosed.
摘要:
Changes in tumor cell RNA and DNA are utilized to detect the progression and the temporal changes in resistance to chemotherapy in human tumors. The present invention provides a method for determining whether human cancer cells are sensitive or resistant to a particular drug, to allow for early detection of drug resistance in order to improve significantly the efficiency of a cancer chemotherapy protocol. The method involves the detection of DNA sequences indicative of drug resistance.
摘要:
A micro-volume fluid injector (10) includes a three-part housing (100, 200, 300) with a conically-shaped recess (106) terminating in an outlet orifice (108) and a conically-shaped plunger (230) which is movable within the recess (106). A piezoelectric disk (270) is secured to the plunger (230) so as to move the plunger in a reciprocating motion to pump the fluid through the orifice (108).
