## Abstract

A method for diagnosing Non-Small Cell Lung Cancer (NSCLC) from a sample extracted from a subject by testing the sample for the presence of biomarkers, the biomarkers being autoantibodies against XAGE1D, LRRFIP2 and GAGE2C. Also claimed are a method of manufacturing a kit, and compositions comprising a panel of said antigens or exosomal autoantibodies.

## Claims

### Claim 1

A composition comprising a panel of antigens comprising biotinylated proteins, wherein the biotinylated proteins consist of X Antigen Family Member 1D (XAGE1D), LLR Binding FLII Interacting Protein 2 (LRRFIP2), G Antigen 2C (GAGE2C), MAGE Family Member A10 (MAGEA10), Signal Transducer and Activator of Transcription 1 (STAT 1), Zinc Ribbon Domain-Containing 1 (ZNRD1), and RAD23 Homolog B (RAD23B).

### Claim 2 (depends on 1)

The composition according to claim 1 wherein each biotinylated protein is formed from a Biotin Carboxyl Carrier Protein folding marker which is fused in-frame with a protein.

### Claim 3 (depends on 1)

The composition according to claim 1 wherein the biotinylated proteins are bound to a streptavidin-coated substrate.

### Claim 4 (depends on 3)

The composition according to claim 3 wherein the substrate comprises a hydrogel-forming polymer base layer.

### Claim 5 (depends on 1)

A composition according to claim 1 wherein the amount of one or more exosomal autoantibody biomarkers binding in vitro to the antigens in a sample from a patient can be measured to determine the presence of non-small cell lung cancer.

### Claim 6

A composition for detecting non-small cell lung cancer, which comprises a panel of antigens bound to a substrate, wherein the antigens consist of X Antigen Family Member 1D (XAGE1D), LLR Binding FLII Interacting Protein 2 (LRRFIP2), G Antigen 2C (GAGE2C), MAGE Family Member A10 (MAGEA 10), Signal Transducer and Activator of Transcription 1 (STAT 1), Zinc Ribbon Domain-Containing 1 (ZNRD 1), and RAD23 Homolog B (RAD23B).

### Claim 7 (depends on 6)

The composition according to claim 6, wherein the substrate comprises a glass slide, biochip, strip, slide, bead, microtitre plate well, surface plasmon resonance support, microfluidic device, thin film polymer base layer, hydrogel-forming polymer base layer, or any other device or technology suitable for detection of antibody-antigen binding.

### Claim 8 (depends on 6)

The composition according to claim 6, wherein the antigens are biotinylated proteins.

### Claim 9 (depends on 8)

The composition according to claim 8, wherein each biotinylated protein is formed from a Biotin Carboxyl Carrier Protein folding marker which is fused in-frame with a protein.

### Claim 10 (depends on 6)

The composition according to claim 6, wherein the substrate is streptavidin-coated.

### Claim 11 (depends on 6)

The composition according to claim 6, wherein the substrate comprises a hydrogel-forming polymer base layer.

### Claim 12 (depends on 6)

The composition according to claim 6 wherein the amount of one or more exosomal autoantibody biomarkers binding in vitro to the antigens in a sample from a patient can be measured to determine the presence of non-small cell lung cancer.

### Claim 13

A composition for detecting non-small cell lung cancer, which comprises a panel of antigens comprising biotinylated proteins, wherein the biotinylated proteins consist of X Antigen Family Member 1D (XAGE1D), LLR Binding FLII Interacting Protein 2 (LRRFIP2), G Antigen 2C (GAGE2C), MAGE Family Member A10 (MAGEA 10), Signal Transducer and Activator of Transcription 1 (STAT 1), Zinc Ribbon Domain-Containing 1 (ZNRD 1), and RAD23 Homolog B (RAD23B).

### Claim 14 (depends on 13)

The composition according to claim 13, wherein each biotinylated protein is formed from a Biotin Carboxyl Carrier Protein folding marker which is fused in-frame with a protein.

### Claim 15 (depends on 13)

The composition according to claim 13, wherein the antigens are bound to a substrate.

### Claim 16 (depends on 15)

The composition according to claim 15, wherein the substrate is streptavidin-coated.

### Claim 17 (depends on 15)

The composition according to claim 15, wherein the substrate comprises a hydrogel-forming polymer base layer.

### Claim 18 (depends on 15)

The composition according to claim 15, wherein the substrate comprises a glass slide, biochip, strip, slide, bead, microtitre plate well, surface plasmon resonance support, microfluidic device, thin film polymer base layer, hydrogel-forming polymer base layer, or any other device or technology suitable for detection of antibody-antigen binding.

### Claim 19 (depends on 13)

The composition according to claim 13 wherein the amount of one or more exosomal autoantibody biomarkers binding in vitro to the antigens in a sample from a patient can be measured to determine the presence of non-small cell lung cancer.
