US Patent:

7422858, Sep 9, 2008

Filed:

Jan 10, 2007

Appl. No.:

11/651638

Inventors:

Brian B. Lentrichia - Acton MA, US
Steven A. Hecht - Cambridge MA, US

Assignee:

Cytyc Corporation - Marlborough MA

International Classification:

C12Q 1/68

US Classification:

435 6, 435 71

Abstract:

A method for analyzing a sample to detect cells infected by Human Papilloma Virus (HPV) is provided. The method includes passing a medium containing the sample across a filter. The filter has a pore size that is greater than a dimension of a HPV particle, but smaller than a dimension of a HPV infected cell, such that most of the HPV particles pass through the filter, while leaving the cells on the filter. The material collected on the filter is then examined to determine if HPV infected cells are present in the material.

International Classification:

G01N 1/30
C12N 1/06
C12N 15/10

Abstract:

The present disclosure describes a method of treating a sample comprising cells with a process of partial lysing. Cells are exposed to a process such as bead beating that lyses some cells in the mixture. The process generates a resultant sample mixture that is suitable for both cell morphology screening and genetic screening. A first portion of the partially lysed sample can be mounted on a slide and observed for atypical cells and cytologic abnormalities. A second portion of the partially lysed sample can be screened for genetic markers known to correlate with a risk of cervical cancer. Surprisingly the presence of beads in the mixture from the partial lysing process does not interfere with slide processing or cellular analysis. The method is particularly useful for cervical screening, where a combination of cytology and genetic screening present a more complete picture of cervical health. The disclosed method streamlines the diagnostic process for protocols that require both types of assays, without compromising screening accuracy.

Steven Hecht - Boston MA, US
Paul MacLean - Westborough MA, US

International Classification:

G01N 1/34

Abstract:

A wash solution for remediating lubricant contamination in cytological specimens includes a Tris-based alkaline buffer solution. The buffer solution may be prepared in methanol, and may include a proton-rich protein, or a basic amino acid, such as arginine, lysine, or guanidine. A method for remediating a specimen contaminated with lubricant includes using the wash solution and/or adding a salt to the final vial prior to preparing the microscope slide. The method may include adding the wash solution to the specimen, centrifuging the specimen and wash solution to form a supernatant and cell pellet, decanting the supernatant, and adding a preservative solution to the cell pellet. The method may further include adding salt to a vial containing the preservative solution and cell pellet.

Filed:

Appl. No.:

14/856604

Inventors:

- Bedford MA, US
Steven Hecht - Boston MA, US
Howard B. Kaufman - Newton MA, US

International Classification:

A61B 10/02
A61B 10/00

Abstract:

The invention provides a device, system and method for sample collection wherein a sample can be separated into multiple portions of sample at the site of collection. The separation of portions of sample occurs by separating parts of the specimen collection device. Each of the separable parts contacting a portion of sample can be deposited into separate vessels. The device reduces the risk of sample contamination, because the separable parts can be separated by the action of a release mechanism that allows a user to separate the parts without touching or otherwise contacting the sample collecting region. The release mechanism may be trigger-activated to expel a separable part of the device.
