Related Product Information for anti-CR1 antibody
Complement receptor type 1 (CR1) is a multi-modular membrane receptor composed of 30 homologous complement control protein modules (CCP) organized in four different functional regions called long homologous repeats (LHR A, B, C, and D). CR1 is a receptor for complement-opsonins C3b and C4b and specifically interacts through pairs of CCP modules located in LHR A, B, and C. Human CR1 plays a role in the clearance of complement opsonized molecules and may facilitate the entry of pathogens into host cells. Lower CR1 expression has been associated with susceptibility to systemic lupus erythematosus (SLE). In contrast, subjects displaying lower CR1 expression are protected against severe manifestations of falciparum malaria. The CR1 gene was shown to be involved in Alzheimer's disease (AD).

NCBI Description

This gene is a member of the receptors of complement activation (RCA) family and is located in the 'cluster RCA' region of chromosome 1. The gene encodes a monomeric single-pass type I membrane glycoprotein found on erythrocytes, leukocytes, glomerular podocytes, and splenic follicular dendritic cells. The Knops blood group system is a system of antigens located on this protein. The protein mediates cellular binding to particles and immune complexes that have activated complement. Decreases in expression of this protein and/or mutations in its gene have been associated with gallbladder carcinomas, mesangiocapillary glomerulonephritis, systemic lupus erythematosus and sarcoidosis. Mutations in this gene have also been associated with a reduction in Plasmodium falciparum rosetting, conferring protection against severe malaria. Alternate allele-specific splice variants, encoding different isoforms, have been characterized. Additional allele specific isoforms, including a secreted form, have been described but have not been fully characterized. [provided by RefSeq, Jul 2008]

Product Notes

The CR1 cr1 (Catalog #AAA8100396) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Anti-CR1/CD35 Antibody, Rabbit Polyclonal reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's CR1/CD35 can be used in a range of immunoassay formats including, but not limited to, Immunohistochemistry-Paraffin (IHC-P). IHC-P: 1:1000-1:4000. Researchers should empirically determine the suitability of the CR1 cr1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "CR1/CD35, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
