Sortilin-related receptor, L(DLR class) A repeats containing is a protein that in humans is encoded by the SORL1 gene. SORL1 (also known as SORLA, SORLA1, or LR11) is a neuronal apolipoprotein E receptor, the gene for which is predominantly expressed in the central nervous system. Mutation of the gene for apolipoprotein E (APOE) is predictive of Alzheimer's disease. Lack of the APOE receptor is suspected to be a contributory factor to Alzheimer's: a significant reduction in SORL1 (LR11) expression has been found in brain tissue of Alzheimer's disease patients. The APOE receptor has also been linked with regulation of amyloid precursor protein, faulty processing of which is implicated in Alzheimer's. A more recent study by a group of international researchers supports the proposition that SORL1 plays a part in seniors developing Alzheimer's disease, the findings being significant across racial and ethnic strata.

Immunohistochemical analysis of paraffin-embedded mouse cerebellum tissue with Rabbit anti-SorLA antibody (HA721337) at 1/1,000 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HA721337) at 1/1,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
