Description

Methods (34)
accession O35235
Source Optimized DNA sequence encoding MouseRANK LigandTNF binding domainwas expressed in Escherichia Coli.
Molecular weight Native Mouse RANK Ligand is a type II transmembrane protein containing an extracellular TNF binding domain, theTNF binding domainhas a calculated molecular mass of approximately20 kDa. Recombinant mouse RANKL is a monomeric protein consisting of amino acid residue subunits. Recombinant RANKLmigrates as an approximately20 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE.
Purity >95%, as determined by SDS-PAGE and HPLC
Biological Activity The ED(50) determined by the dose-dependent stimulation of IL-8 production in Human PBMCs is ≤8 ng/ml.

Endotoxin Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than.1 ng/µg(1EU/µg).
Presentation Recombinant mouse RANK Ligand was lyophilized from a.2 μm filtered PBS solution.
Reconstitution A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than.1 mg/mL. This solution can then be diluted into other buffers.
Storage The lyophilized protein is stable for at least years from date of receipt at -20° C. Upon reconstitution, this cytokine can be stored in working aliquots at° -° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Methods

Osteoblast, osteoclast and macrophage differentiation.

RANKL
  • Bone marrow derived monocytes were seeded in 24-well culture plates and induced to differentiate into macrophages or osteoclasts via the addition of M-CSF or M-CSF + RANKL respectively.

Osteoclastogenesis assays

  • Osteoclastogenesis assays were performed as in 5 cells were plated in each well of a 24-well dish with 60 ng/mL RANKL for 3 days.
  • After 3 days, 2×103 MDA-231, shControl, or shEGFR-MDA-231 cells were plated with the bone marrow cells, with 60 ng/mL RANKL and 10 ng/mL MCSF and grown for 3 days before TRAP staining.
  • For TRAP staining, cells were washed with 1×PBS, fixed with ice cold methanol for 10 minutes, and stained in fresh TRAP solution for 15 minutes at 37°C.
  • TRAP solution was replaced with 1×PBS for cell counting under the microscope.

Polarized membrane extensions mediate osteoclast fusion.

recombinant mouse RANKL
  • (D, top) Immunoblot analysis of lysates of RAW264.7 macrophages stimulated with RANKL for the indicated times with antibodies to Ser473-phosphorylated (p) or total forms of Akt.

Osteoclast differentiation assay

  • Osteoclast differentiation assay was performed as we described.+ T cells or Treg cells (1 × 106/ml) were pre-activated with 2.5 μg/ml anti-CD3 and 1.25 μg/ml anti-CD28 monoclonal mouse antibodies for 12 h as we described,,
