What is a Peptide

what is a peptide bond
A peptide is a biologically occurring chemical compound containing two or more amino acids connected to one another by peptide bonds. A peptide bond is a covalent bond that is formed between two amino acids when a carboxyl group or C-terminus of one amino acid reacts with the amino group or N-terminus of another amino acid in a condensation reaction (a molecule of water is released during the reaction). The resulting bond is a CO-NH bond and forms a peptide, or amide molecule. Likewise, peptide bonds are amide bonds.
The word “peptide” itself comes from πέσσειν, the Greek word meaning “to digest.” Peptides are an essential part of nature and biochemistry, and thousands of peptides occur naturally in the human body and in animals. In addition, new peptides are being discovered and synthesized regularly in the laboratory as well. Indeed, this discovery and innovation in the study of peptides holds great promise for the future in the fields of health and pharmaceutical development.

Peptide Purity

How to Achieved and Verified Peptide Purity

we provide peptides that exceed 99% purity. Using state-of-the-art solution and solid phase peptide synthetic technology, Peptide Sciences is able to offer the finest quality peptides and proteins fit for any research study or application. Peptide purity is achieved and verified through uncompromising manufacturing and production processes, quality control measures, and the implementation of both high-performance liquid chromatography and mass spectrometry analysis.

HPLC and Mass Spectrometry

High performance liquid chromatography, or HPLC, is a scientific technique used to separate, identify, and quantify each component in a mixture. It is a superior process that allows highly accurate peptide testing to be accomplished. Mass spectrometry (MS) is a technique used to measure masses within a sample by ionizing chemical species and sorting the ions based on their mass to charge ratio. The results are plotted with the ion signal as a function of the mass to charge ratio. Both methods are highly accurate peptide testing techniques and scientifically prove the purity and identity of peptides ordered from here

Recommended Peptide Purity Level?

We provide only the highest purity peptides (>99% pure) for sale for research and development use. However, preparations of peptides synthesized for research by many other manufacturers can vary widely in purity. Occasionally, researchers can wonder what the minimum acceptable level of peptide purity is for their given purpose. Generally, the higher the peptide purity level, the more favorable the preparation; critically, for certain applications (such as in vitro studies or clinical trials), only exceedingly pure peptides will be appropriate (greater than 98% purity). However, there are some applications for which a lower peptide purity would be acceptable. The minimum recommended peptide purity level for a given application will therefore depend upon that specific application. Examples of minimum acceptable purity levels are as follows.
Highly Pure (>95% Peptide Purity)
• In vitro and in vivo studies
• Clinical trials
• Drug studies in which peptides are used as pharmaceuticals
• Cosmetic peptides for cosmeceuticals
• Crystallography
• Monoclonal antibody production
• Quantitative protease studies and enzyme studies
• Quantitative receptor – ligand interaction studies
• Quantitative blocking and competitive inhibition studies
• Quantitative ELISA and RIA protocol standard
• Chromatography standard

Mid-range Peptide Purity (>85%)

• Peptide blocking studies (Western blot)
• Phosphorylation studies
• NMR studies
• Cell attachment studies
• Phosphorylation studies
• Semi-quantitative studies of enzyme-substrate interactions
• Epitope mapping tests
• Biological activity testing
Lower Peptide Purity (>70%)
• Peptide arrays
• Performing an ELISA standard for measuring titers of antibodies
• Antigens for polyclonal antibody production or affinity purification
Peptides with greater purity are appropriate for use in an application with a lower minimum acceptable level of purity. We provide exceedingly high purity peptides that will meet or exceed all previously stated purity requirements.
