From: Expression of the NEK family in normal and cancer tissue: an immunohistochemical study
Immunohistochemistry tissue microarray (TMA) of specimens of human normal and malignant lung and thyroid tissue. The immunostaining of the NEK proteins by using the anti-NEK1 (8 μg/mL), NEK2 (8 μg/mL), NEK3 (8 μg/mL) and NEK5 (8 μg/mL) antibodies. The brownish-red region indicates the immunoreactivity of the advanced biotin-free polymer (DAKO, Carpenteria, CA, USA) with the indicated human NEK protein expressed in the tissue of the lung and thyroid, after being labeled with a chromogenic substrate (DAB - Sigma, St Louis, MA, USA)
