The present invention relates to the field of anastasis, i.e., the process of reversal of apoptosis. More specifically, the present invention provides methods and compositions useful for studying anastasis. In one embodiment, a tracking construct of the present invention comprises Lyn11-NES-ERT2-DEVD-rtTA-3xFLAG-DEVD-ERT2-NES. In another embodiment, a construct comprises Lyn11-NES-DEVD-rtTA-3xFLAG. In a further embodiment, a construct comprises ERT2-DEVD-rtTA-3XFLAG-DEVD-ERT2

Synthetic fragment antigen-binding (Fab) antibodies are disclosed that bind to an N-terminal activation site of BCL-2-associated X-protein (BAX) and inhibit BAX activation. Also disclosed are methods of using the Fabs for measuring inactive monomeric BAX levels, screening for small molecules that bind to an N-terminal activation site of BAX, inhibiting apoptotic cell death, and predicting the ability of a cancer therapy to promote apoptotic cell death.

The present disclosure provides a method for screening, isolating and purifying analytes.

The present invention relates to a method for detecting apoptosis using a phosphatidylinositol phosphate-binding material, a method for screening anticancer agents, a method for screening apoptosis-inhibiting materials, and a method for inhibiting phagocytosis.

Embodiments of the present invention allow for verifying the destruction of cells by another party. The destruction of cells can be verified by generating a value of an indicator (e.g., a bar code), where the value depends on some feature of the destruction. The party destroying the cells provides the value of the indicator as evidence that the cells have been destroyed. Embodiments may include a method of verifying the destruction of a cell. The method may include running a medium including a dead cell through an assay using a system. Running the medium through the assay may generate a value of an indicator to signify that the assay has been run. The value may identify the system, the cell, or the destruction mode of the cell. The method may further include receiving a verification code to acknowledge that the value is valid.

Provided herein are methods and assays for isolating and culturing seborrheic keratosis cells ex vivo. Also provided herein are screening assays using cultured seborrheic keratosis cells and methods for treating seborrheic keratosis in a subject.

Disclosed herein are antibodies having binding specificity to the amino acid sequences Ala Ser Ser Gly Leu Thr Val Glu Val Asp (SEQ ID NO:1) and Thr Val Glu Val Asp (SEQ ID NO:14), and methods of detecting cell death in a sample, comprising contacting the sample with a first antibody specific for a C-terminal amino acid sequence Ala Ser Ser Gly Leu Thr Val Glu Val Asp (SEQ ID NO:1) or Thr Val Glu Val Asp (SEQ ID NO:14) of a CK18 protein fragment having a C-terminal amino acid sequence of Val Glu Val Asp (SEQ ID NO:2) and a second antibody that specifically binds an epitope that is present in both full-length CK18 and the CK18 protein fragment, and that does not overlap with SEQ ID NO:1 or SEQ ID NO:14, under conditions such that the CK18 protein fragment present in the sample specifically binds to the first antibody and the second antibody, wherein one of the antibodies is bound to a solid support and the other antibody is bound to a detection moiety capable of producing a signal; optionally removing any unbound or excess material; and detecting the signal from the detection moiety, wherein the signal is positively correlated with the presence of the CK18 protein fragment in the sample.

A high throughput automated assay platform for temporal image processing of cell growth and colony formation before and after radiation therapy treatments. The platform is designed to compute and monitor a therapeutic protocol by measuring sensitivity of cell growth to treatment based on a radiation therapy protocol. The platform is designed to detect relationships between the temporal images being tracked to colony formation behaviour.

Cell-separation systems and methods utilizing cell-specific microbubble tags and ultrasound-based separation are described. The methods are useful for simplification of time-consuming and costly cell purification procedures and real time apoptosis detection.

Methods of generating conditionally active proteins that target senescent cells and which are conditionally active in an extracellular environment of a senescent cell. The methods include methods using libraries of evolved proteins and assays employing physiological concentrations of components of bodily fluids. Also disclosed are conditionally active proteins for killing or removing senescent cells, antibodies and antibody fragments, conjugates and pharmaceutical compositions employing these conditionally active proteins and methods for treatment of age-related diseases, conditions or disorders using same. The conditionally active proteins may be further evolved, conjugated to other molecules, masked, reduced in activity by attaching a cleavable moiety.
