Validation Data Gallery

• 

  WB analysis using 83200-3-RR (same clone as 83200-3-PBS)

  Various lysates were subjected to SDS PAGE followed by western blot with 83200-3-RR (IGFBP4 antibody) at dilution of 1:10000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 83200-3-PBS in a different storage buffer formulation.

• 

  WB analysis using 83200-3-RR (same clone as 83200-3-PBS)

  Various lysates were subjected to SDS PAGE followed by western blot with 83200-3-RR (IGFBP4 antibody) at dilution of 1:10000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 83200-3-PBS in a different storage buffer formulation.

• 

  IHC staining of human intrahepatic cholangiocarcinoma using 83200-3-RR (same clone as 83200-3-PBS)

  Immunohistochemical analysis of paraffin-embedded human intrahepatic cholangiocarcinoma tissue slide using 83200-3-RR (IGFBP4 antibody) at dilution of 1:200 (under 20x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 83200-3-PBS in a different storage buffer formulation.

• 

  FC experiment of A549 using 83200-3-RR (same clone as 83200-3-PBS)

  1x10^6 A549 cells were intracellularly stained with 0.4 ug IGFBP4 Recombinant antibody (83200-3-RR, Clone:230543F8) and CoraLite®488-Conjugated AffiniPure Goat Anti-Rabbit IgG(H+L) (SA00013-2)(red), or 0.4 ug Isotype Control (blue). Cells were fixed with 4% PFA and permeabilized with Flow Cytometry Perm Buffer (PF00011-C). This data was developed using the same antibody clone with 83200-3-PBS in a different storage buffer formulation.

• 

  Affinity and Kinetic Characterization of 83200-3-RR

  Biolayer interferometry (BLl) kinetic assays of 83200-3-RR against Human IGFBP4 were performed. The affinity constant is 0.776 nM.

Background Information

IGFBP4, also named as IBP4, is a 258 amino acid protein, which contains one IGFBP N-terminal domain and one thyroglobulin type-1 domain. IGFBP4 is the smallest member of the insulin-like growth factor binding protein family (IGFBP). It is a hepatic protein that plays a role in modulating the activity and bioavailability of IGF-I. The expression of IGFBP4 was found to increase under conditions of hypoxia. IGFBP4 is highly expressed in adipocytes and osteoblasts and is inhibitory of IGFs in vitro.
