ErbB4 (c-erbB4, HER4)

c-erbB-4 is the fourth member of class I receptor kinase family. HER-4 is most predominantly expressed in several breast carcinoma cell lines, and in normal skeletal muscle, heart, pituitary, brain, and cerebellum. Breast tumor cell lines T47-D, MB-453, BT-474 and H3396 are found to have the highest levels of mRNA, and intermediate levels are seen in MCF-7, MDA-MB-330 and MDA-MB-361. Expression of erbB-4 is low or absent in some breast tumor cell lines such as MDA-MB-231, MDA-MB-157, MDA-MB-468, and SKBR-3.\n\nApplications:\nSuitable for use in Western Blot and Immunohistochemistry. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 2-4ug/ml for 2 hours at RT.\nImmunohistochemistry (Formalin/paraffin): 1:50 for 60 min. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0 for 10-20 min followed by cooling at RT for 20 min.\nOptimal dilutions to be determined by the researcher. \n\nPositive Control: \nBreast carcinoma, T47D cells.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
