Introduction

Glial cell line-derived neurotrophic factor receptor alpha-1 (GFRα-1) is a key receptor for glial cell line-derived neurotrophic factor (GDNF), playing an essential role in neural development, kidney function, and neuroprotection. The Human GFR Alpha-1/GDNF R ELISA Kit is a highly sensitive immunoassay designed for quantitative measurement of GFRα-1 levels in human serum, plasma, and other biological fluids. This article explores the importance, methodology, and applications of the Human GFR Alpha-1 ELISA Kit in biomedical research and clinical diagnostics.

What is GFR Alpha-1 (GFRα-1)?

GFRα-1 is a glycosylphosphatidylinositol (GPI)-anchored protein that interacts with RET tyrosine kinase to mediate GDNF signaling. This pathway is crucial for:

• Neurodevelopment and Neuronal Survival: Supports dopaminergic neurons, making it relevant in Parkinson’s disease research NIH.
• Renal Development and Repair: Essential for nephron formation and kidney regeneration NIDDK.
• Peripheral Nervous System Regulation: Affects Schwann cell survival and nerve repair NIH.

Importance of Measuring GFR Alpha-1 in Humans

Assessing GFRα-1 levels is critical for:

• Early Detection of Neurodegenerative Diseases: Potential biomarker for Alzheimer’s and Parkinson’s disease NIA.
• Kidney Function and Disease Monitoring: Regulates renal development and recovery after injury NIDDK.
• Cancer Research: Implicated in glioblastoma and neuroblastoma progression NCBI.

Human GFR Alpha-1/GDNF R ELISA Kit: Overview

The Human GFR Alpha-1 ELISA Kit is a sandwich enzyme-linked immunosorbent assay (ELISA) designed for precise quantification of GFRα-1 in human samples CDC.

Kit Components

• Pre-coated Microplate: Wells coated with anti-GFRα-1 antibodies.
• Standard GFRα-1 Solution: Used for calibration.
• Enzyme-Conjugate: HRP-conjugated secondary antibodies.
• Substrate and Stop Solutions: Colorimetric detection reagents.
• Washing Buffer: For removing unbound substances FDA.

Methodology

The Human GFR Alpha-1 ELISA follows a four-step process:

1. Sample Addition: Serum/plasma samples added to microplate wells.
2. Antibody Binding: GFRα-1 binds to specific antibodies USDA.
3. Enzyme Reaction: A colorimetric reaction occurs upon substrate addition.
4. Measurement: Optical density read at 450 nm to determine GFRα-1 levels NIH.

Performance Characteristics

• High Sensitivity: Detects low picogram levels of GFRα-1.
• Specificity: No cross-reactivity with related proteins.
• Reproducibility: Consistent intra- and inter-assay precision FDA.
