Validation Data Gallery

• 

  WB analysis using 83743-2-RR (same clone as 83743-2-PBS)

  Various lysates were subjected to SDS PAGE followed by western blot with 83743-2-RR (Cathepsin D antibody) at dilution of 1:10000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 83743-2-PBS in a different storage buffer formulation.

• 

  WB analysis of MCF-7 using 83743-2-RR (same clone as 83743-2-PBS)

  MCF-7 cells were subjected to SDS PAGE followed by western blot with 83743-2-RR (Cathepsin D antibody) at dilution of 1:10000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 83743-2-PBS in a different storage buffer formulation.

• 

  Sandwich ELISA standard curve of MP00695-4

  Sandwich ELISA standard curve of MP00695-4, Human Cathepsin D Recombinant Matched Antibody Pair - PBS only. 83743-6-PBS was coated to a plate as the capture antibody and incubated with serial dilutions of standard Eg1053. 83743-2-PBS was HRP conjugated as the detection antibody. Range: 0.156-10 ng/mL

• 

  Sample test of MP00695-4

  Saliva of eight individual healthy human donors was measured. The human Cathepsin D concentration of detected samples was determined to be 139.6 ng/mL with a range of 102.4 - 182.3 ng/mL.

• 

  Sample test of MP00695-4

  Human milk of eight individual healthy human donors was measured. The human Cathepsin D concentration of detected samples was determined to be 580.4 ng/mL with a range of 270 - 1,071.8 ng/mL.

• 

  Sample test of MP00695-4

  For the A431 supernatant, the mean human Cathepsin D concentration was determined to be 301.05 ng/mL.

• 

  Sample test of MP00695-4

  Serum of sixteen individual healthy human donors was measured. The human Cathepsin D concentration of detected samples was determined to be 147.3 ng/mL with a range of 43.2 - 224.2 ng/mL.

• 

  FC experiment of MCF-7 using 83743-2-RR (same clone as 83743-2-PBS)

  1x10^6 MCF-7 cells were intracellularly stained with 0.25 ug Cathepsin D Recombinant antibody (83743-2-RR, Clone:240775E7) and PE-Conjugated Goat Anti-Rabbit IgG(H+L)(red), or 0.25 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 83743-2-PBS in a different storage buffer formulation.

• 

  Cytometric bead array standard curve of MP00695-1

  Cytometric bead array standard curve of MP00695-1, Cathepsin D Recombinant Matched Antibody Pair, PBS Only. Capture antibody: 83743-1-PBS. Detection antibody: 83743-2-PBS. Standard: Eg1053. Range: 0.78-100 ng/mL.

Background Information

CTSD (Cathepsin D) also named CPSD, belongs to the peptidase A1 family. It is ubiquitously expressed and is involved in proteolytic degradation, cell invasion, and apoptosis. Human CTSD is synthesized as a 52-kDa precursor that is converted into an active 48-kDa single-chain intermediate in the endosomes, and then into a fully active mature form, composed of a 34-kDa heavy chain and a 14-kDa light chain, in the lysosomes. It is a lysosomal acid protease found in neutrophils and monocytes and involved in the pathogenesis of several diseases such as breast cancer and possibly Alzheimer disease (PMID: 27114232, PMID: 30717773, PMID: 30051532).
