Animal-Free RANK L/TNFSF11 Protein, Mouse (His)

RANKL (TNFSF11), a type II transmembrane protein, is a receptor activator of NF-κB (RANK) ligand. RANKL is an activator of RANK. When binding to RANK, it induces the differentiation of monocyte/macrophage-lineage cells into osteoclasts and leads to osteoclast precursor maturation. RANKL is critical for osteoclasts maturation, bone modeling, and bone remodeling, as well as the development of lymph nodes (LNs). Animal-Free RANK L/TNFSF11 Protein, Mouse (His) is a recombinant mouse RANKL (P143-D316) with C-terminal His tag, which is produced in E.coli^[1][2].

RANKL (TNFSF11) belongs to TNF family. RANKL is a type II transmembrane protein and is a receptor activator of NF-κB (RANK) ligand. RANKL is an activator of RANK. RANKL binds to RANK and induces the differentiation of monocyte/macrophage-lineage cells into osteoclasts and leads to osteoclast precursor maturation. In bone tissue, RANKL is expressed by osteoblasts, osteocytes and immune cells, especially in osteoblasts and osteocytes^[1]. RANKL is also expressed by T cells and increases proliferation and survival of dendritic cells^[2]. In mice, RANKL/RANK signaling attenuates inflammation in ischemic brains through a Toll-like receptor signaling pathway^[4].
RANKL consists of cytoplasmic domain (1-47), helical domain (48-68), and extracellular domain (69-317). The soluble chain (140-317) is released when cleaved by enzymes such as matrix metalloproteinases (MMP3 or 7) and ADAM^[1][3].
RANKL is critical for osteoclasts maturation, bone modeling, and bone remodeling, as well as the development of lymph nodes (LNs)^[1].

RANKL (mouse, 3 ng/mL, 4 days) induces osteoclast differentiation from RAW264.7 cells, and can be inhibited by Resveratrol^[5].
RANKL (mouse,1 ng/mL, -3 h) induces NF-κB activation in murine hepatocyte cell line (AML-12) ^[6].

RANKL (mouse, i.c.v., 5 ng in 2 μL) reduces IL-1β, MCP-1, IL-6 and TNFα expression in WT mice^[4].
RANKL (mouse, i.p., 1-1 μg) protects against hepatic ischemia/reperfusion liver injury in mice^[6].

Measure by its ability to induce osteoclast differentiation in RAW264.7 cells. The ED₅₀ for this effect is <2 ng/mL.

Approximately 20.35 kDa

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from a solution containing 1X PBS, pH 8.0, trehalose.

<0.1 EU per 1 μg of the protein by the LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
