表达区间及表达系统（Source）
PE-Labeled Human ROR1, His Tag (RO1-HP2E3) is produced via site-specific conjugation of PE to Human ROR1 (30-403), His Tag under optimal conditions with a proprietary technology. Human ROR1, His Tag (RO1-HP2E3) is expressed from human 293 cells (HEK293). It contains AA Gln 30 - Glu 403 (Accession # Q01973-1).
Predicted N-terminus: Gln 30

活性（Bioactivity）-FACS
5e5 of anti-ROR1 CAR-293 cells were stained with 100 μL of 1:50 dilution (2 μL stock solution in 100 μL FACS buffer) of PE-Labeled Human ROR1 Protein, His Tag (Cat. No. RO1-HP2E3) and negative control protein respectively. PE signal was used to evaluate the binding activity (QC tested).
Protocol
背景（Background）
Tyrosine-protein kinase transmembrane receptor ROR1 is also known as Neurotrophic tyrosine kinase, receptor-related 1 (NTRKR1), which belongs to the protein kinase superfamily or tyr protein kinase family or ROR subfamily. ROR1 contains 1 FZ (frizzled) domain, 1 Ig-like C2-type (immunoglobulin-like) domain, 1 kringle domain, 1 protein kinase domain. ROR1 is expressed at high levels during early embryonic development. The expression levels drop strongly around day 16 and there are only very low levels in adult tissues. Isoform Short is strongly expressed in fetal and adult CNS and in a variety of human cancers, including those originating from CNS or PNS neuroectoderm. ROR1 could interact with casein kinase 1 epsilon (CK1ε) to activate phosphoinositide 3-kinase-mediated AKT phosphorylation and cAMP-response-element-binding protein (CREB), which was associated with enhanced tumor-cell growth.
