The invention provides anti-human pro-epiregulin and anti-human amphiregulin antibodies and methods of using the same. Anti-EREG antibodies raised against amino acids 148-169 and 156-169 of the human EREG protein, and anti-AREG antibodies raised against amino acids 238-252 of the human AREG protein are disclosed. Methods of using these antibodies to detect EREG and AREG and kits and other products for performing such methods are also disclosed.

Materials and methods for performing histochemical assays for human pro-epiregulin and amphiregulin

Antibodies, compositions, systems, and methods for detecting C4.4a, for example immunohistochemistry methods for detecting C4.4a using a C4.4a antibody. The antibody may be obtained by immunizing a host with a C4.4a protein such as a peptide downstream of the signal peptide. The antibodies may be adapted to detect the uPAR-like domain 1 and uPAR-like domain 2. Also featured are methods for diagnosing C4.4a-associated tumors using C4.4a antibodies disclosed herein.

Antibodies, compositions, and immunohistochemistry methods for detecting C4.4a

The invention provides programmed death-ligand 1 (PD-L1) antibodies and methods of using the same.

Anti-PD-L1 antibodies and diagnostic uses thereof

Provided herein are B7-H3 antibodies, fragments of such antibodies, and compositions comprising the same. The antibodies, antibody fragments and compositions are useful in a number of analytical methods, including immunohistochemical and immunocytochemical detection and analysis of B7-H3. Also provided herein are isolated peptides and fusion proteins containing immunogenic determinants for said B7-H3 antibodies, animals immunized with the peptides and fusion proteins, isolated B cells obtained from the animals, and hybridomas made from the isolated B cells.

Anti-B7-H3 antibodies and diagnostic uses thereof

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.

Anti-GPNMB antibodies and diagnostic uses thereof

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.

Anti-OX40 antibodies and diagnostic uses thereof

The invention provides antibodies that bind specifically to human indoleamine 2,3-dioxygenase 1 (IDO1), nucleic acids encoding the same, 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).

Anti-indoleamine 2,3-dioxygenase 1 antibodies and diagnostic uses thereof

Provided herein are PD-L1 antibodies and methods for using the same for detecting human PD-L1 protein in biological samples. The PD-L1 antibodies and methods may be useful for diagnosing a medical condition associated with elevated PD-L1 levels (e.g., cancer) in subjects in need thereof and in evaluating the efficacy of a particular therapeutic regime in a subject diagnosed as having a PD-L1-related medical condition, among other uses.

PD-L1 antibodies and uses thereof

Provided herein are B7-H3 antibodies, fragments of such antibodies, and compositions comprising the same. The antibodies, antibody fragments and compositions are useful in a number of analytical methods, including immunohistochemical and immunocytochemical detection and analysis of B7-H3. Also provided herein are isolated peptides, compositions, and fusion proteins containing immunogenic determinants for said B7-H3 antibodies, animals immunized with the peptides and fusion proteins, isolated B cells obtained from the animals, and hybridomas made from the isolated B cells.
