Why is Protein Sequencing Useful

2022-04-25T17:51:47-04:00September 3rd, 2021|Articles|

Protein sequencing is a method that typically utilizes mass spectrometry (MS) to determine the amino acid code of a protein1. Prior to the development of mass spectrometry, Edman degradation, a method involving the stepwise degradation of peptides to derive the order of amino acids, was the mainstream approach. Nowadays, mass spectrometry is favored due to its ease of use and high throughput capabilities, though Edman degradation is still employed for specific applications in which the technique is well suited.

Antibody Validation and its Use Cases

2022-04-25T18:20:45-04:00August 4th, 2021|Articles|

Antibodies are used in a variety of ways in academia and industry, from tools to therapeutics. Because antibodies are produced using live processes, which are naturally error-prone, validation is required from time to time. Furthermore, to develop biological therapeutics, the protein sequence must be confirmed as part of the regulatory process.

De Novo Protein Sequencing vs DNA Sequencing

Written by Yuning Wang, PhD August 1, 2021 What is DNA Sequencing? DNA sequencing is the process of determining the precise order of four nucleotides bases—adenine (A), guanine (G), cytosine (C), and thymine (T)—that make up the DNA molecule. From Sanger sequencing to next-generation sequencing (NGS), DNA sequencing’s accessibility and ease [...]
