Product Specifications

Immunogen

This CD38 Antibody (HB7) - Chimeric was developed against viable cells (1 x 10^7) of the human cell line, BJAB (Human Burkitt lymphoma B cell line), which was were injected intraperitoneally into 8-week-old BALB/c mice.

Specificity

This antibody binds to an epitope between amino acids 273-285 of human CD38, an approximately 45 kDa type II transmembrane protein, expressed on essentially all pre-B lymphocytes, plasma cells, and thymocytes. Also present on activated T lymphocytes, natural killer (NK) lymphocytes, myeloblasts, and erythroblasts. Bimodally expressed during B cell development, modulating from high in immature cells to low in intermediate ones and back to high on mature B cells. This antibody competes with clone AT13/5 (Ab00289) (Ellis 1995).

Flow Cytometry: CD38 Antibody (HB7) - Chimeric [NBP2-52647] - CD38 Antibody (HB7) [NBP2-52647] - Flow Cytometry using anti-CD38 antibody HB7. Human lymphocytes were stained with an isotype control (panel A) or the rabbit-chimeric version of HB7 (NBP2-52647, panel B) at a concentration of 1 ug/mL for 30 mins at RT. After washing, bound antibody was detected using a AF488 conjugated donkey anti-rabbit antibody and cells analysed on a FACSCanto flow cytometer.

Background: CD38

CD38 (cluster of differentiation 38), previously known as T10, is a 46 kDa type II transmembrane glycoprotein (1). CD38 is expressed in both lymphoid and non-lymphoid tissue including in thymocytes, T and B lymphocytes, myeloid cells, natural killer cells, plasma cells, erythrocytes, and additionally in cells of the brain, pancreas, muscle, and bone (1,2). Structurally, CD38 is an "L"-shape which is formed by two separate domains connected by a three peptide-chain hinge region (2). The N-terminal domain is composed of five alpha-helices and two beta strands, while the C-terminal domain contains a four-stranded parallel beta-sheet and two long and two short alpha-helices (2). The CD38 molecule is located on chromosome 4 and is 300 amino acids (aa) in length with a theoretical molecular weight of 34 kDa that functions as both a receptor and an enzyme (1-6). As a receptor, CD38 interacts with its ligand CD31, which is largely expressed in endothelial cells (2-6). As an ectoenzyme, CD38 has a role in calcium signaling and is responsible for the conversion of nicotinamide adenine dinucleotide (NAD) into adenosine diphosphate-ribose (ADPR) or cyclic ADPR and the conversion of phosphorylated NAD (NADP) into nicotinic acid adenine dinucleotide phosphate (NAADP) (2-6).

As described above, CD38 is highly expressed in plasma cells and, as a result, is a target for treating multiple myeloma (MM), the cancer of white blood cells (4,6). The anti-CD38 monoclonal antibody daratumumab is one specific treatment for MM (4,6). Daratumumab has been shown to target MM cells through antibody-dependent cellular cytotoxicity and antibody dependent cellular phagocytosis (4). Additionally, CD38 has a potential role in neurodegenerative disorders and neuroinflammation as elucidated CD38's high expression in neurons, astrocytes, and microglia along with its enzymatic role in NAD degradation (3). Reduced NAD levels is a consequence of aging and occurs during neurodegeneration (3). Furthermore, murine studies have found that CD38 deletion inhibits neuroinflammation and neurodegeneration and therefore might be a potential therapeutic target (3). Similarly, CD38 inhibitors, like quercetin and luteolin, are used to treat age-related diseases and metabolic disorders (7).
