- Extra Details:
- MaxLight™650 is a new Far-IR stable dye conjugate comparable to Alexa Fluor™647, DyLight™649, Cy5™ and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (655nm); Emission (676nm); Extinction Coefficient 250,000. The ErbB-2 (HER-2/neu) proto-oncogene encodes a 185kD transmembrane receptor protein. It has partial homology with the epidermal growth factor (EGF) receptor and shares intrinsic tyrosine kinase activity with the receptor. ErbB-2 heterodimerizes with the EGF receptor, ErbB-3 receptor, and the ErbB-4 receptor. In human breast and ovarian cancers the receptor is activated through amplification and over-expression of the wild-type gene. This alteration occurs in 25%-30% of cases and is associated with a poor prognosis. The poor prognosis of ovarian and breast cancer patients associated with ErbB-2-mediated high rate of tumor cell proliferation. ErbB-2 may play a role in the genesis of human gastric, endometrial and salivary gland cancers. The concentration of ErbB-2 protein in serum can be a sensitive indicator for prognosis of the gastric carcinoma that expressed ErbB-2. ErbB-2 oncoprotein is detectable in adenocarcinomas as well as in transitional cell carcinomas. Applications: Suitable for use in Immunofluorescence, FLISA, Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: Immunohistochemistry: Formalin-fixed, paraffin-embedded sections Optimal dilutions to be determined by the researcher.
