A method for determining the nature of a sample is provided, wherein the presence or absence of at least one marker small non-coding RNA in the sample is detected. Suitable marker small non-coding RNAs for different samples such as blood, saliva, semen and vaginal secretions are provided. Also provided are suitable kits and methods for identifying marker small-non coding RNAs.

Method for determining the origin of a sample

The invention relates to a process and a reagent kit for obtaining clear solutions containing cell contents from biological samples in a high throughput process, comprising the steps of preparing a plurality of protein-containing solutions which contain insoluble ingredients, in separate chambers of a multi-chamber filtration unit, eliminating insoluble ingredients by filtering the solutions through the multi-chamber filtration unit with the application of a pressure differential, while preventing cross contamination between adjacent chambers by chemical and/or mechanical means, and collecting the individual filtrates separately in collecting containers, as well as a process for recovering cell contents from the clear solutions obtained. The invention further relates to the use of an apparatus for recovering clear protein-containing solutions from biological samples.

Automated protein purification the multiwell format by vacuum filtration

The present invention provides a method for separation of a particulate matrix from a solution while reducing loss of particles during separation steps. Methods are also disclosed for isolation of molecules of interest using affinity particles or beads, wherein at least one step of the isolation is conducted in the presence of a detergent. The presence of detergent reduces the loss of matrix particles and enhances reproducibility and yield of the molecule of interest. The invention makes possible the manual and automated processing of affinity beads, especially magnetic beads, in multi-well as well as single-well vessels with significantly reduced bead loss, as compared with similar processes conducted in the absence of detergent.
