New lipid binding protein 1

A method of detecting the presence or absence of new lipid binding protein 1 (“NLBP1”) polypeptide in a tumor tissue comprising:

• contacting a tumor tissue sample from a subject having a tumor with an antibody which is immunospecific for NLBP1 polypeptide, and detecting the presence or absence of said polypeptide, wherein said polypeptide is selected from the group consisting of:
• (a) a polypeptide encoded by a polynucleotide comprising the nucleotide sequence of SEQ ID NO:1;
• or
• (b) a polypeptide comprising the amino acid sequence of SEQ ID NO:2;
• (c) a polypeptide having at least 95% identity along its entire length to the amino acid sequence of SEQ ID NO:2 and which hybridizes to the complement of SEQ ID NO:1 under stringent hybridization conditions comprising overnight incubation at 42° C. in a solution comprising:
• 50% formamide, 5×SSC (150 mM NaCl, solution, 10% dextran sulphate, and 20 microgram/ml denatured, sheared salmon sperm DNA;
• followed by washing the filters in 0.1×SSC at 65° C.
