The application is to antibodies which have been labelled with polyenzymes (multiple enzymes), specifically polyperoxidases, for use in direct immunohistochemical assays of tissues. The antibodies used diagnostically may also be antibodies which are used therapeutically.

Provided herein are methods for capturing an analyte from a first region of interest of a biological sample on a substrate, where the biological sample comprises the first region of interest and a second region, and where the method includes contacting the second region with a sealant in order to create a hydrophobic seal thereby preventing an interaction between an analyte from the second region with a capture domain of a capture probe.

Disclosed herein are in vitro methods of multiple staining and slide preparation for a cytopathological sample, such as a urine sample. These methods enable simultaneous staining of biomarkers and cytopathological stains to greatly enhance confidence in identifying atypical cells such as cancer cells. Also disclosed herein are methods of using said staining and preparation methods for the detection of bladder cancer using urine samples from a patient. These methods offer increased sensitivity and specificity over conventional bladder cancer detection methods. Also disclosed herein are the urinary exfoliated cells stained according to the methods provided herein.

Methods, systems, and compositions featuring a solid, dissolvable reagent composition for delivering the reagent, such as an antibody, probe, chromogen, etc., to a sample. The present invention also features methods of producing said compositions, and automated systems featuring the use of the solid, dissolvable reagent compositions. The solid, dissolvable reagent composition may comprise a water-soluble polymer film, such as a polyvinyl alcohol film, infused with the reagent, wherein when applied to the sample, the water-soluble polymer film with reagent contacts the sample (e.g., tissue) and dissolves.

A method of simultaneously detecting target nucleic acids and target proteins in a biological sample, comprising treating the biological sample with a crosslinking agent, that is after incubating it with a primary antibody that detects the target proteins and prior to detecting the target nucleic acids by in situ hybridization.

A method to produce a rapid immunohistochemical detection of an antigen from a biological sample is provided. Preferably, the method may be used for rapid immunohistochemical staining of a biological sample that allows completion of the staining process in less than ten minutes, such as during a cancer removal procedure. In some embodiments, the method may include the steps of: depositing a section of the biological sample on a slide; permeabilizing the section of the biological sample; incubating the section of the biological sample with a secondary antibody having a detectable label; removing unbound secondary antibody from the section of the biological sample; mounting the section of the biological sample; and detecting secondary antibody bound to the section of the biological sample.

The present disclosure provides an antibody for predicting breast cancer prognosis and a nucleic acid encoding sequence thereof, and uses of the same. The antibody for predicting breast cancer prognosis of the present disclosure achieves the effect of predicting breast cancer prognosis through various efficacy experiments.

The present invention is intended to provide a method for determining the prognosis of a hormone receptor-positive cancer (for example, an ERα-positive breast cancer, an ERα-positive endometrial cancer, etc.) or a method for assisting the determination of the prognosis, and a method for evaluating the sensitivity of the cancer to antihormone therapy or a method for assisting the evaluation of the sensitivity of the cancer to antihormone therapy. Specifically, the present invention relates to a method for determining the prognosis of a hormone receptor-positive cancer, or a method for assisting the determination of the prognosis, which comprises the following steps (a) and (b): (a) a step of detecting Fbxo22-positive cancer cells in a sample derived from the cancer tissues; and (b) a step of calculating the percentage of the Fbxo22-positive cancer cells to the cells present in the sample.

The present invention provides a method for selecting a cancer patient for whom a combination therapy with a retinoid and a cancer treatment agent is effective, which comprises a step of selecting a cancer patient having a malignant tumor with the infiltration of cancer-associated fibroblasts in the stroma. In addition, the present invention provides a medicament which comprises a cancer patient having a malignant tumor with the infiltration of cancer-associated fibroblasts in the stroma is a subject and is administered in combination of a retinoid and a cancer therapeutic agent.

Methods and compositions for accurate identification of Parkinson's disease are disclosed. More particularly, the disclosure is directed to the determination of Parkinson's disease in ante-mortem tissue samples.
