About CD35
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 genome is polymorphic at this locus with allele-specific splice variants encoding different isoforms, based on the presence/absence of long homologous repeats (LHRs). 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 this gene have been associated with gallbladder carcinomas, mesangiocapillary glomerulonephritis, systemic lupus erythematosus, sarcoidosis and Alzheimer's disease. Mutations in this gene have also been associated with a reduction in Plasmodium falciparum rosetting, conferring protection against severe malaria. [provided by RefSeq, May 2020]

About CF680R
CF®680R from Biotium is a fluorophore with an excitation peak at 680 nm and an emission peak at 701 nm. It can be useful in both fluorescence microscopy and flow cytometry. For microscopy, CF®680R has been specifically validated in super-resolution imaging by STORM, STED and 2-Photon microscopy. It is spectrally similar to Alexa Fluor™ 680, IRDye® 680 and Cy5.5.
