<strong>Figure 4 Immunocytochemistry Validation of BAFF in HL60 Cells</strong><br> Immunocytochemical analysis of HL60 cells using anti-BAFF antibody (2221) at 1 μg/ml. Cells was fixed with formaldehyde and blocked with 10% serum for 1 h at RT; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4˚C. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin.

Background:
BAFF Antibody: Members in the TNF superfamily regulate immune responses and induce apoptosis. A novel member in the TNF family was recently identified by several groups and designated BAFF (for B cell Activating Factor belonging to the TNF Family), BLyS (for B Lymphocyte Stimulator), TALL-1 (for TNF- and ApoL-related Leukocyte-expressed Ligand), and THANK (for TNF Homologue that Activate Apoptosis, NF-κB and c-jun N-terminal Kinase). BAFF/BLyS was characterized as a B cell activator since it induced B cell proliferation and immunoglobulin secretion. Three receptors for BAFF were recently identified and designated TACI, BCMA and BAFF-R. BAFF and its receptors are essential for B cell development, survival, and humoral immune responses. BAFF is involved in the development of autoimmune diseases including systemic lupus erythaematosus and rheumatoid arthritis.

DISCLAIMER:
Optimal dilutions/concentrations should be determined by the end user. The information provided is a guideline for product use. This product is for research use only.
Immunogen:
Anti-BAFF antibody (2221) was raised against a peptide corresponding to 16 amino acids near the carboxy?terminus of human BAFF.

The immunogen is located within the last 50 amino acids of BAFF.
ISOFORMS:
Human BAFF has 3 isoforms, including isoform 1 (285aa, 31kD), isoform 2 (266aa, 29kD) and isoform 3 (164aa, 17.6kD). Mouse BAFF has 2 isoforms, including isoform 1 (309aa, 34kD) and isoform 2 (290aa, 32kD). Rat BAFF has only one isoform (274aa, 30kD). 2221 can detect two longer human isoforms, mouse and rat.
