Provided herein are biomolecular hybridization devices comprising a substrate with a permanently and covalently attached surface of functional groups and an adsorbed monolayer of unmodified, single-stranded oligonucleotides all of which are 10 to about 24 bases in length as a saturated film of constrained oligonucleotides on the surface via direct non-covalent phosphate-surface adsorptive contact of substantially all phosphate groups of each oligonucleotide. The constrained oligonucleotides are effective to dissociably hybridize to a complementary single-stranded nucleic acid with asymmetric, non-helical base pairing and without oligonucleotide dissociation from the surface of the device. Also, provided are methods for hybridizing solution-state target nucleic acids to probe nucleic acids and for identifying a nucleotide sequence to which a nucleotide-binding protein binds using the biomolecular hybridization devices.

A system for separating nucleated cells from a blood sample includes a charge-flow separator (CFS), which separates blood into fractions according to the surface charge density characteristics coupled with an affinity-filtration separator which either outputs a separated blood fraction to the CFS or receives a separated blood fraction from the CFS. The system permits separation of nucleated fetal red blood cells, erythroid progenitor cells and other nucleated cells found in blood samples.

Situ and in vitro hybridization method and buffer

A method and single solution denaturation and hybridization solution useful with synthetic oligonucleotide probes for hybridizing DNA or RNA sequences by in situ hybridization. The inventive protocol employs synthetic oligonucleotide probes and a glycerol-based hybridization solution which is particularly useful in fluorescence labeling of chromosomes X, Y, 13, 18 and 21 in human lymphocytes, amniocytes and metaphase chromosomes, with the label being sufficiently stable to permit archival storage of the labeled sample for later hybridization or analysis.

A method for enriching rare cell populations from a whole blood sample by separating rare cell fractions from whole blood sample according to the relative charge density and/or the relative binding affinity for a leukocyte depletion solid phase matrix is described. The enrichment method may be operated stand alone, or as a pre or post-processing step in conjunction with a charge-flow separation method.

System and method for enrichment of rare cell population from whole

A charge-flow separation apparatus (CFS) for enriching rare cell populations, particularly fetal cells, from a whole blood sample by separating the rare cell fractions from whole fractions according to the relative-charge density and/or the relative binding affinity for a leukocyte depletion solid phase matrix is described. The apparatus having an internal cooling system allows for dissipating heat generated by the electric field of the apparatus. The internal cooling system, consisting of a plurality of cooling tubes to circulate coolant material, prevents cellular degradation typically associated with the high heat generated by the electric field and permits the use of a higher voltage gradient to shorten separation times.
