Description
Human PDAP1 (Pdgfa Associated Protein 1) ELISA Kit
The Human PDAP1 (PDGFA-associated protein 1) ELISA Kit is a reliable and accurate assay designed for the precise detection of PDAP1 levels in human samples such as serum, plasma, and cell culture supernatants. This kit boasts high sensitivity and specificity, ensuring consistent and trustworthy results for a variety of research applications.PDAP1 is a critical protein that interacts with PDGFA (Platelet-Derived Growth Factor Alpha) and is involved in various cellular processes such as cell growth, differentiation, and migration.
Dysregulation of PDAP1 has been linked to diseases like cancer and fibrosis, making it a valuable biomarker for studying these conditions and exploring potential therapeutic interventions.With the Human PDAP1 ELISA Kit, researchers can gain valuable insights into the role of PDAP1 in disease pathogenesis and progression, ultimately advancing our understanding of complex biological processes and paving the way for innovative treatments.

This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human PDAP1. Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human PDAP1 and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human PDAP1, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by adding Stop Solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human PDAP1. The concentration of Human PDAP1 in samples can be calculated by comparing the OD of the samples to the standard curve.
| UniProt Protein Function: | PDAP1: Enhances PDGFA-stimulated cell growth in fibroblasts, but inhibits the mitogenic effect of PDGFB. Belongs to the PDAP1 family. |
| UniProt Protein Details: | Chromosomal Location of Human Ortholog: 7q22. 1 Biological Process: cell proliferation; signal transduction |
| NCBI Summary: | The protein encoded by this gene is a phosphoprotein that may upregulate the PDGFA-stimulated growth of fibroblasts and also downregulate the mitogenicity of PDGFB. The encoded protein in rodents has been shown to bind PDGFA with a low affinity. [provided by RefSeq, Dec 2010] |

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e. g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.

- Set standard, test sample and control (zero) wells on the pre-coated plate and record theirpositions. It is recommended to measure each standard and sample in duplicate. Note: addall solutions to the bottom of the plate wells while avoiding contact with the well walls. Ensuresolutions do not foam when adding to the wells.
- Aliquot 100 µL of standard solutions into the standard wells.
- Add 100 µL of Sample / Standard dilution buffer into the control (zero) well.
- Add 100 µL of properly diluted sample (serum, plasma, tissue homogenates and otherbiological fluids) into test sample wells.
- Cover the plate with the sealer provided in the kit and incubate for 90 min at 37 °C.
- Aspirate the liquid from each well, do not wash. Immediately add 100 µL of BiotinylatedDetection Ab working solution to each well. Cover the plate with a plate seal and gently mix. Incubate for 1 hour at 37 °C.
- Aspirate or decant the solution from the plate and add 350 µL of wash buffer to each welland incubate for 1-2 minutes at room temperature. Aspirate the solution from each well andclap the plate on absorbent filter paper to dry. Repeat this process 3 times. Note: a microplatewasher can be used in this step and other wash steps.
