Abstract: The invention relates to predicting cancer relapse or predicting patient survival by determining a level of serum thymidine kinase 1 (STK1) material in a body sample from a patient diagnosed with hematological cancer using an antibody or a fragment thereof specifically binding to a serum form of human TK1. The determined level of STK1 material is compared with a threshold value selected based on an age of the patient. Cancer relapse is then predicted based on the comparison.

Abstract: Methods for detecting acute kidney injury in an individual comprise (a) contacting a body fluid sample from the individual with an assay device including neutrophil gelatinase-associated lipocalin (NGAL) antibody and a detectable label, to allow complexing of NGAL protein in the sample with NGAL antibody, and determining an amount of complex formed between NGAL protein from the sample and NGAL antibody in the assay device using the detectable label, wherein NGAL antibody in the device has binding capacity with more than two NGAL protein epitopes, and wherein the amount of the formed complex represents a level of acute kidney injury. Methods for determining an origin of NGAL protein in a sample from an individual include the step of determining relative amounts of monomeric, dimeric and heterodimeric forms of NGAL protein in the sample and allow improved diagnosis and therefore better targeted treatment.

Abstract: Methods for determining the occurrence or level of a mammalian protein in a sample and methods for determining the capability of a compound to transform or to inhibit the transformation of a selected mammalian protein in pro-phospholipase B form to an enzyme active phospholipase B form employ a pro-phospholipase B (PLB-II) mammalian protein which comprises at least one SU2 subunit comprising SEQ ID NO: 3 and having a molecular weight within the range of 30-60 kDa. Methods for determining the capability of a compound to enhance or inhibit the enzymatic activity of a selected protein having phospholipase B enzyme activity employ a protein comprising an activated form of such a pro-phospholipase B (PLB-II) mammalian protein.

Abstract: A novel mammalian protein related to human hypothetical protein FLJ22662 (SEQ ID NO: 1) and homologous hypothetical proteins from mammal species other than Homo sapiens. The protein is expressed in neutrophils and is characterized as a phospholipase B of a novel family (PLB-II). The protein is characterized in comprising one or two single chain polypeptide SU subunits that are different with respect to their amino acid sequences (i.e. at least one SU1 subunit and/or at least one SU2 subunit), where the amino acid sequence of: i) SU1 comprises SEQ ID NO: 2 or a variant thereof ii) SU2 comprises SEQ ID NO: 3 or a variant thereof. There is also described an antibody preparation which is specifically directed against the mammalian protein and a method for determining the occurrence or level of an analyte in a sample.

Abstract: Diagnostic methods comprise measuring specifically the level of at least one iso-eosinophilic cationic protein (iso-ECP) in a sample from an individual to be diagnosed, and comparing the measured level of the iso-ECP with a predetermined level of the iso-ECP. The iso-ECP is cytotoxic and the cytotoxicity of the iso-ECP is not capable of neutralization by the monoclonal antibodies EG1 and EG2. Anti-iso-ECP antibody which may be used in the diagnostic methods specifically binds to a cytotoxic isoform of ECP having an epitope which is unique for the native form of the cytotoxic iso-ECP.
