ErbB4 Antibody (MA1-861) in ICC/IF
Immunofluorescent analysis of ErbB4 (green) showing staining in the cytoplasm of SK-BR-3 cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with an ErbB4 monoclonal antibody (Product # MA1-861) in 3% BSA-PBS at a dilution of 1:50 and incubated overnight at 4°C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjug... View More

产品详细信息
MA1-861 detects Her-4 from human and mouse samples.
MA1-861 has been successfully used in immunoprecipitation, immunohistochemical, and Western blotting procedures. By Western blot, this antibody detects ~185 kDa protein representing Her-4 from human A431 cell and mouse NIH3T3/HER4 cell extracts.This antibody has also been used in immunohistochemical, using paraffin embedded mouse NIH3T3 cells.
MA1-861 immunizing peptide corresponds to amino acid residues 1250 to 1264 of human Her-4 oncoprotein.
靶标信息
Oncogene ERBB4 (HER4) is a member of the type I receptor protein tyrosine subfamily that includes EGFR, ERBB2, and ERBB3. ERBB4 binds and is activated by neuregulins and other factors and induces a variety of cellular responses including mitogenesis and differentiation. ErbB 4 is activated by neuregulins and NTAK (neural and thymus derived activator for ErbB kinases). ErbB 4 is a receptor for heregulin and is capable of mediating HGL-stimulated tyrosine phosphorylation of itself. Like other protein kinases, ErbB 4 mediate most of the signal transduction in eukaryotic cells, regulating cellular metabolism, transcription, cell cycle progression, cytoskeletal rearrangement and cell movement, apoptosis, and differentiation. ErbB 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, MDA-MB-453, BT-474 and H3396 are found to have the highest levels of mRNA, and intermediate levels are seen in MCF-7, MDAMB-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. ErbB 4 levels have been found to be elevated in certain human tumor cell lines suggesting that it may play a role in some malignancies.
