Abstract: A cell filtration assembly adapted to capture cells from a biological sample during centrifugation includes a filter support member including a sample well and a filter membrane that spans the sample well. In some cases, the filter support member and/or the filter membrane may be adapted to be sectioned. In some cases, a protective element may be disposed over at least a portion of the filter support member in order to protect the filter support member from tissue processing reagents during processing of the cells captured from the biological sample.

Abstract: A rolling hamper with a body with two sides, a front, a bottom and an expanded back portion. The body includes ventilation holes which may have fortified edges to avoid hazards for users. Wheels are removably coupled at the two back corners so that the hamper can be tipped back and rolled.

Abstract: A one-piece, open top container with two or more parabola-shaped securing slots for securing handled bags used as liners.

Abstract: A bicycle pedal assembly having a pedal body rotatably coupled to a pedal shaft. A bore receiving the pedal shaft passes through the pedal body. A semi-cylindrical shoulder extends outwardly from an exterior surface of the shaft. A bushing is positioned within the bore to rotatably support the pedal shaft. An inner surface of the shoulder rotatably engages the external end of the bushing, so that the second end of the shaft is movably connected to the pedal body without assistance of any fasteners.

Abstract: The invention is a chain unit comprising first and second link units, a unitary outer plate, and first and second pins. Each link unit comprises two inner plates with two rollers positioned therebetween. The outer plate straddles and is secured to the link units. Outer plate comprises two walls and a bridge positioned therebetween that spans the tooth engaging space between link units. The unitary construction of the outer plate provides a structural integrity that prevents the plates from separating when the chain is exposed to force. A plurality of chain units can be linked together to form a chain.

Abstract: Nucleic acid molecules that encode R2 subunit protein and topoisomerase I protein, fragments thereof, recombinant expression vectors and host cells are disclosed. Oligonucleotide molecules with nucleotide sequences complimentary to a nucleotide sequence encode R2 subunit protein and topoisomerase I protein are disclosed.
