The present disclosure provides methods, compositions, and systems for distributing polymerase compositions into array regions. In particular, the described methods, compositions, and systems utilize density differentials and/or additives to increase efficiency in the distribution of polymerase compositions to a surface as compared to methods utilizing only diffusion control.

The present disclosure relates to methods and systems for partition-free quantification of molecules. The methods and systems provided allow a sample to be amplified such that discrete amplification spots can be analyzed to quantify the number of molecules without requiring physical partitions in order to separate the amplification spots.

A method for lysing cells and shearing genomic DNA to reduce viscosity of the cell lysate. Cells may be lysed to release cell lysate, and the cell lysate may be treated with focused acoustic energy to shear genomic DNA so that the genomic DNA is sheared to DNA fragments having a fragment size no larger than 50% of the starting base pair size of the genomic DNA. Lysing and DNA shearing may be done by acoustic energy and in a single vessel, allowing for automated handling of cell lysate.

The invention relates to compositions and methods for isolating extracellular vesicles (EVs) from a biological fluid sample. The compositions and methods of the invention are based on the combination of a polycation with an extracellular matrix forming polymer. Extracellular vesicles (EVs) are isolated from biological fluids such as blood, serum, plasma, saliva, urine or cerebrospinal fluid, or from the conditioned medium of a cell culture, such as an adult stem cell culture. The use of the isolation methods and compositions of the invention results in a higher EVs recovery, enrichment in exosomes, simplicity, cost-effectiveness, and in the isolation of EVs that retain their biological activities in vitro.

The object of the present invention is a method for detection of a nucleic acid in a sample by nucleic acid separation and enrichment by using a bidirectional electro-hydrodynamic flow in a non-newtonian liquid medium, where the method further comprises the addition of probes intended to hybridize with a target nucleic acid so as to introduce a modification of the molecular weight of the target nucleic acid during hybridization with the probes in order to allow the separation of nucleic acid/probe complexes from the nucleic acid alone or the probes alone when the sample is subject to hydrodynamic and electrical action in order to allow the detection of the target nucleic acid.
