CD239 antibody | BRIC221
Mouse anti Human CD239 antibody, clone BRIC221 (MCA1982) used to look for blocking of Lu-Fc to endogenous α5 laminin in kidney sections.
Image caption:
Lu/B-CAM binding assay on tissue sections.
(A) Binding of Lu-Fc to laminin α5 in adult mouse kidney sections. Sections were incubated with Lu-Fc (upper panel) or Fc (lower panel) at room temperature for 1 hour. Endogenous laminin α5 and bound Lu-Fc were detected with anti-laminin α5 domain LEb/L4b and anti-human IgG, as indicated. Merged pictures showed that laminin α5 and Lu-Fc co-localized at basement membranes. Arrows indicate glomeruli, laminin α5-rich structures. Bar, 100 μm. (B) Binding of Lu-Fc to laminin α5 in adult mouse skeletal muscle sections. Endogenous laminin α2 (upper panel) and α5 (lower panel) were detected with antisera. Bound Lu-Fc was detected with an antibody against human IgG as described above. Lu-Fc only bound to the basement membranes containing α5, primarily neuromuscular junctions. Arrowheads indicate neuromuscular junctions. Bar, 50 μm. (C) Inhibitory effects of anti-Lu/B-CAM antibodies on Lu-Fc binding to laminin α5. After preincubation with anti-Lu/B-CAM antibodies, Lu-Fc was used in the binding assay on tissue sections. Antibody 87207 inhibited the binding of Lu-Fc to endogenous laminin α5.

Mouse anti Human CD239 antibody, clone BRIC221 epitope mapping by adsorbtion with lutheran deletion and chimeric mutant proteins as measured by ELISA
Image caption:
Identifying the IgSF domains recognized by anti-Lu/B-CAM antibodies.
(A) Diagram of the deletion and chimeric mutant proteins designed to narrow the epitopes of anti-Lu/B-CAM antibodies. For chimeric mutant proteins, the D1 or D1–D2 domains of Lu-Fc were replaced with the analogous domains of melanoma cell adhesion molecule (Mel-CAM). The deletion and chimeric mutant proteins were fused with an IgG Fc domain tag. (B) The mutant proteins purified from conditioned media of HEK293 transfectants were subjected to SDS-PAGE on a 7.5% gel under reducing conditions. Protein was stained with Coomassie Brilliant Blue. Molecular mass standards are indicated. (C) ELISA using the indicated anti-Lu/B-CAM antibodies absorbed with the various recombinant proteins. Wells were coated with 3 μg/ml of Sol-Lu. The mutant proteins were mixed with the diluted antibodies at 1 μg/ml. Each bar represents the mean of triplicate assays. Error bars indicate standard deviation.

Antibody Quality and Performance Guarantee
| Mouse anti Human CD239 antibody, clone BRIC221 recognizes human CD239, also known as Lutheran antigen or basal cell aghesion molecule.CD239 is a 597 amino acid, ~85 kDa single pass type I membrane glycoprotein. Clone BRIC221 recognizes a monomorphic determinant expresses on both the 85 and 78 kDa Lutheran (Lu) glycoforms (El Nemer et al. 1998). BRIC 221 recognizes an epitope in the fourth extracellular domain of Lu glycoprotein (Parsons et al. 1997). Lutheran glycoprotein is a member of the immunoglobulin superfamily and was designated CD239 (B-CAM) at the 7th leucocyte typing workshop. CD239 is expressed by erythrocytes in the peripheral blood. |
