Product Description
Tissue-like quantitative reference standard used as a biological calibrator to determine the expression level of PR in tissue specimens. Comprising of four formalin fixed, paraffin embedded, high density cell line cores with a quantitative range of PR expression.
Four formalin fixed paraffin embedded cell lines with a quantitative range of expression for Progesterone Receptor (PR).
- Cell line A: Ductal Carcinoma (negative)
- Cell line B: Breast Adenocarcinoma (low)
- Cell line C: Ductal Carcinoma (medium)
- Cell line D: Ductal Carcinoma (high)
Cells are fixed in 10% neutral buffered formalin and paraffin wax embedded.
Sections are cut at 4μm, mounted on positively charged slides and baked overnight at 37°C. Cell microarrays (CMA) contain cores that are 1.5-2mm in diameter and 3-3.5mm in length. It is possible to obtain up to 400 sections depending on thickness and batch cutting.
