Technical Data
APRIL, ED, Blocking Peptide (a Proliferation Inducing Ligand, TALL-2, TNF and ApoL-related Leukocyte-expressed Ligand 2, TRDL-1a, TNF-related Death Ligand 1a, TNFSF13)
Molecular Biology Storage: -20CShipping: Blue Ice
Control Peptide for A2299-98.

Members in the TNF superfamily regulate immune responses and induce apoptosis. A novel member in the TNF family was recently identi ed by several groups and designated APRIL (for a proliferation-inducing ligand), TALL-2 (for TNF-and ApoL-related Leukocyte-expressed Ligand 2), and TRDL-1a (for TNF related death ligand 1a) in human and mouse (1-4). Two receptors for APRIL were recently identi ed and designated TACI and BCMA (5-7). APRIL stimulates B and T cell proliferation, triggers humoral immune responses, activates NF-kB and induces cell death (1-7). APRIL and its close relative of BlyS and their receptors BCMA and TACI are involved in diseases of autoimmunity and cancer (8,9).

Suitable for use in ELISA, Antibody Blocking. Not suitable for use in Western Blot due to low molecular weight. Other applications not tested.

Recommended Dilution:
Antibody Blocking: Equal volume peptide to antibody (AA99-98) for 30 minutes at RT.
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage, store at -20C. Aliquots are stable for at least 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
