Abstract: The present disclosure provides methods, compositions, and systems employing blocked primers. Aspects of the disclosure include providing a blocked primer reaction mixture that includes a blocked primer and a template nucleic acid component from a single cell; unblocking the blocked primer to produce an active primer reaction mixture and subjecting the activated primer reaction mixture to primer extension conditions, such as nucleic acid implication conditions.

Abstract: The present disclosure provides methods, device, assemblies, and systems for dispensing and visualizing single cells. For example, provided herein are systems and methods for dispensing a dispense volume into a plurality of wells of a multi-well device, where, on average, a pre-determined number of cells (e.g., 1-20) are present in the dispense volume, and determining, via a cellular label, the number of cells present in each of the plurality of wells. Such dispensing and cell detection may be repeated a number of times with respect to wells identified as having less than the pre-determined number of cells in order increase the number wells in the multi-well device containing the desired number (e.g., a single cell).

Abstract: Value-assigned solutions having predetermined concentrations of recombinant Lp-PLA2 are described herein. In particular, described herein are solutions of rLp-PLA2 that are stable for an extended period of time. Kits and assays include these calibration solutions, as well as methods of making and using them are described.
