# Custom Peptides for Scientific Research Applications
## Introduction to Custom Peptides
Custom peptides have become indispensable tools in modern scientific research. These short chains of amino acids, typically ranging from 2 to 50 residues, are synthesized to meet specific research requirements. Unlike commercially available peptides, custom peptides are designed with precise sequences, modifications, and purity levels tailored to individual experimental needs.
## Key Applications in Research
### 1. Antibody Production and Epitope Mapping
Custom peptides play a crucial role in antibody development. Researchers use them to:
– Generate antibodies against specific protein regions
– Map antibody binding sites (epitopes)
– Validate antibody specificity
### 2. Drug Discovery and Development
Pharmaceutical research heavily relies on custom peptides for:
– Screening potential drug candidates
– Studying protein-protein interactions
– Developing peptide-based therapeutics
### 3. Cell Signaling Studies
Scientists utilize custom peptides to investigate:
– Kinase and phosphatase activities
– Protein phosphorylation events
– Intracellular signaling pathways
## Advantages of Using Custom Peptides
Custom peptides offer several benefits for research applications:
– Precise sequence control
– Ability to incorporate modifications (phosphorylation, acetylation, etc.)
– High purity levels (typically >95%)
– Flexibility in length and composition
– Cost-effective compared to full-length proteins
## Common Modifications Available
Researchers can request various modifications to enhance peptide functionality:
Modification Type | Purpose
N-terminal acetylation | Mimics natural protein processing
