Validation Data Gallery

• 

  WB analysis of THP-1 using 84160-3-RR (same clone as 84160-3-PBS)

  THP-1 cells were subjected to SDS PAGE followed by western blot with 84160-3-RR (GPNMB antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 84160-3-PBS in a different storage buffer formulation.

• 

  WB analysis using 84160-3-RR (same clone as 84160-3-PBS)

  Various lysates were subjected to SDS PAGE followed by western blot with 84160-3-RR (GPNMB antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 84160-3-PBS in a different storage buffer formulation.

• 

  Sandwich ELISA standard curve of MP01096-1

  Sandwich ELISA standard curve of MP01096-1, Human GPNMB Recombinant Matched Antibody Pair - PBS only. 84160-3-PBS was coated to a plate as the capture antibody and incubated with serial dilutions of standard Ag14124. 84160-2-PBS was HRP conjugated as the detection antibody. Range: 0.781-50 ng/mL.

• 

  Sample test of MP01096-1

  Plasma of six individual healthy human donors was measured. The GPNMB concentration of detected samples was determined to be 12.18 ng/mL with a range of 3.43-30.61 ng/mL.

• 

  Sample test of MP01096-1

  Serum of six individual healthy human donors was measured. The GPNMB concentration of detected samples was determined to be 5.69 ng/mL with a range of 3.96-8.17 ng/mL.

• 

  Cytometric bead array standard curve of MP01096-1

  Cytometric bead array standard curve of MP01096-1, GPNMB Recombinant Matched Antibody Pair, PBS Only. Capture antibody: 84160-3-PBS. Detection antibody: 84160-2-PBS. Standard: Ag14124. Range: 0.781-100 ng/mL.

• 

  Affinity and Kinetic Characterization of 84160-3-RR

  Biolayer interferometry (BLl) kinetic assays of 84160-3-RR against Human GPNMB were performed. The affinity constant is below 1 pM.

Background Information

GPNMB also known as HGFIN, osteoactivin, and DC-HIL, is a type I membrane glycoprotein involved in various biological processes, including inflammation, invasion and metastasis of malignant tumors, cell differentiation, and tissue regeneration. GPNMB shows expression in the lowly metastatic human melanoma cell lines and xenografts but does not show expression in the highly metastatic cell lines. GPNMB acts as an osteogenic factor that stimulates osteoblast differentiation in vivo and in vitro.
