The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/2000 - 1/10000. Detects a band of approximately 150 kDa (predicted molecular weight: 105 kDa).
IP Use at 2-5 µg/mg of lysate.
IHC-P 1/200 - 1/1000. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.


  • RelevanceSFRS8 is a human homolog of Drosophila splicing regulatory protein. This gene autoregulates its expression by control of splicing of its first two introns. In addition, it also regulates the splicing of fibronectin and CD45 genes. Multiple alternatively spliced variants have been identified. Two alternatively spliced variants have been characterized to date.
