Abstract: The present application discloses anti-GPNMB antibodies and methods of using the same. The antibodies are selected to bind to an epitope located in a C-terminal fragment of the protein and are selected for specificity in immunohistochemical assays. The antibodies are useful in, for example, immunohistochemical methods of detecting GPNMB-positive cells in tumors.

Abstract: The invention provides antibodies that bind specifically to human indoleamine 2,3-dioxygenase 1 (IDO1), and methods of using the same. The antibodies are capable of binding to a sequence comprising SEQ ID NO: 1 and specifically bind to human IDO1 in formalin fixed paraffin embedded tissues. The antibodies are useful in a number of different analytical techniques, including immunohistochemistry (IHC) and immunocytochemistry (ICC).

Abstract: The invention provides antibodies immunoreactive with human OX40 and methods of using the same. The antibodies are reactive with a portion of the C-terminus of the human OX40 protein that includes amino acids 266-277. The antibodies are useful for detecting OX40 protein expression in human tissue samples, including by immunohistochemistry, immunofluorescence, or immunoblot.

Abstract: Provided herein are novel PD-L1 antibodies and methods for using the same for diagnosing a medical condition associated with elevated PD-L1 levels (e.g., cancer) in subjects in need thereof and antigen binding fragments thereof. The PD-L1 antibodies and antigen binding fragments are also useful in evaluating the efficacy of a particular therapeutic regime in a subject diagnosed as having a PD-L1-related medical condition.
