Our Abpromise guarantee covers the use of ab189925 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-P||1/300. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
For unpurified use at 1/100-1/250. See IHC antigen retrieval protocols.
FunctionThis is probably a cell growth or differentiation factor receptor with a tyrosine-protein kinase activity.
Tissue specificityExpressed in brain. Expression is increased in primary gliomas.
Involvement in diseaseNote=A chromosomal aberration involving ROS1 is found in a glioblastoma multiforme sample. An intra-chromosomal deletion del(6)(q21q21) is responsible for the formation of GOPC-ROS1 chimeric protein which has a constitutive receptor tyrosine kinase activity.
Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily.
Contains 9 fibronectin type-III domains.
Contains 1 protein kinase domain.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human lung carcinoma tissue sections labeling ROS1 with Purified ab189925 at 1:300 dilution (5.23 μg/ml). Heat mediated antigen retrieval was performed using EDTA Buffer, pH9.0. Tissue was counterstained with hematoxylin. ImmunoHistoProbe one step HRP Polymer (ready to use) secondary antibody was used at 1:0 dilution. PBS instead of the primary antibody was used as the negative control.
Immunohistochemical analysis of paraffin-embedded Human lung carcinoma tissue labeling ROS1 with unpurified ab189925 at 1/250 dilution followed by prediluted HRP Polymer for Rabbit IgG. Counter stained with hematoxylin. (Inset: negative control).
Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
