Methods are provided for assaying neoplastic cells and/or neoplasia-related cells. Aspects of the methods involve detecting heterogeneity, per cell programmed-death ligand 1 (PD-L1) expression, and/or proliferation of neoplasia and/or neoplasia-related cells. Aspects of the methods include cytometrically assaying a labeled cell suspension to quantify per cell heterogeneity, per cell PD-L1 expression, proliferation, and/or other parameters to detect whether a neoplastic cell is present in the neoplasia sample. Aspects of the provided methods also include treating a subject based on the outcome of such an assay. In addition, kits that find use in practicing the subject methods are also provided.

Methods of assaying neoplastic and neoplasia-related cells and uses thereof

Methods are provided for assessing a cellular breast sample. Aspects of the methods include flow cytometrically obtaining sample data, cellular data, and combinations thereof, and then assessing the cellular breast sample based on the obtained data. In addition, compositions, e.g., kits, systems and programming, useful in practicing various embodiments of the methods are provided.

Methods of assessing cellular breast samples and compositions for use in practicing the same

Methods are provided for detecting the per cell programmed-death ligand 1 (PD-L1) expression of neoplasia cells. Aspects of the methods include cytometrically assaying a labeled cell suspension to quantify per cell PD-L1 expression to detect whether a neoplastic cell that expresses PD-L1 above a predetermined threshold is present in the neoplasia sample. In addition, kits that find use in practicing the subject methods are also provided.

Methods of detecting per cell PD-L1 expression and uses thereof

An quantitative ZAP-70 assay is provided, with ZAP-70+ and ZAP-70&#x2212; controls, normal human blood controls, an improved antibody with better signal to noise ratio, and using the median MEFL that is calibrated using a standard curve.

Quantitative ZAP-70 assay

A new method of cell fixation using a mild denaturing heat and the fixative PERMIFLOW&#x2122; or similar fixative that preserves cell morphology, light scatter profiles, nucleic acid content, cell surface epitopes and unmasks internal epitopes previously not available. The method can be combined with analysis of each of these parameters by flow cytometry and thus has application in drug screening and patient or tumor monitoring protocols.
