PR Dynamic Range Analyte Control^DR

The Progesterone Receptor Analyte Control^DR has four cell line cores which demonstrate a range of expression for PR: negative, low/intermediate, intermediate/high, and high.
HistoCyte Laboratories control slides and blocks are made from cultured human cell lines to provide the required range of expression of a specific biomarker. The cell lines are processed using proprietary methods that allow for the creation of a high density embedded cell block with cores that retain their cellular morphology. Available as pre-cut unstained slides or as cell microarray blocks for sectioning.

Ideal for use as a same slide control for immunohistochemistry (IHC) and in situ hybridization (ISH).
The Progesterone Receptor Analyte Control^DR histology slides have four cell line cores providing a dynamic range of expression of PR: negative, low/intermediate, intermediate/high, and high. Analyte controls are placed at one end of slide, allowing sample application on same slide for valid comparison.
The Progesterone Receptor Analyte Control^DR cell microarray block contains four cell line cores that are 2 mm in diameter and between 3.0-3.5 mm in length. The cell microarray block may yield over 300 sections depending on thickness.

Cell microarray blocks are fixed in 10% neutral buffered formalin and embedded in paraffin wax. Pre-cut unstained slides are prepared from 4 μm thick sections, mounted on positively charged slides, and dried at 37 °C overnight.
