TNFSF11: mRNA transcript variants, genomic loci and sequence conservation A.

a rabbit anti-human RANKL polyclonal antibody
  • Color coded schematics showing the exon structure for the human TNFSF11 mRNA transcripts aligned with the known RANKL protein domains.

Enzyme-linked immunosorbent assay (ELISA)

  • RANKL protein concentration was measured using a sandwich ELISA developed in our laboratory.
  • Recombinant human RANKL was used as a standard.
  • 100 μl/well OPG-FC (&system) was coated onto 96-well microplates at final protein concentrations of 0.25 μg/ml in 50 mM carbonate-bicarbonate buffer, pH 9.6, and incubated overnight at 4°C.
  • The plates were blocked using 5% skim milk, 0.1% Tween-20 in PBS (pH 7.4).
  • 100 μl of supernatant from cultured cells was applied to each well and incubated at room temperature for 2 hours.
  • After washing, the plates were incubated with rabbit anti-hRANKL polyclonal antibody , 250 ng/well for 1 hour at room temperature followed by incubation with an anti-rabbit IgG horseradish peroxidase conjugate .
  • The bound horseradish peroxidase was assayed with 3, 3′, 5, 5′-tetramethylbenzidine (TMB) as substrate, and the reaction was stopped with 2M H2SO4.
  • ODs were determined at 450 nM.
  • The detection limit for this assay was 35 pg/ml.

Sandwich ELISA

  • 96-well maxisorp plates were coated with the capture antibody overnight, then blocked with 5% FCS in PBS for 1 hour, then washed.
  • Then, the protein standard was added, and plates were incubated for 2 hrs at 37°C.
  • Plates were washed and incubated with a biotinylated detection antibody for 1 hour at 37°C.
  • After washing, plates were incubated with HRP-conjugated streptavidin for 30 min at room temperature and washed again.
  • Plates were developed using the tetramethylbenzidine peroxidase substrate system and absorbance was measured at 450-615 nm using an automated plate reader.

Western Blot

  • The Recombinant immunogen was migrated by 12% SDS-PAGE and transferred to a 0.2 um PVDF membrane.
  • After blocking the membrane in blocking buffer (5% milk powder in 20 mM Tris-HCl pH 7.5, 500 mM NaCl, 0.1% (v/v) Tween 20 , the membrane was incubated with primary antibody ( at 4°C overnight.
  • Peroxidase-linked secondary anti-rabbit were used to detect the bound primary antibodies.
  • Enhanced chemiluminescence (ECL) reagents were used to visualize
