Chemical and Physical Properties

Molecular Characteristics

TESA 10MG is a synthetic peptide with a complex amino acid sequence. Its molecular formula is C₂₂₁H₃₇₆N₇₂O₆₈S, giving it a molecular mass of 4947.61 daltons. The compound is registered under CAS number 1000157-72-1.

The presence of sulfur in the molecular formula indicates the inclusion of sulfur-containing amino acids such as methionine or cysteine within the peptide chain. This characteristic contributes to the compound’s specific three-dimensional structure and stability profile.

Physical Form and Storage

The product is supplied as a lyophilized (freeze-dried) powder within a sterile, sealed vial. Lyophilization preserves the chemical integrity of the peptide by removing water content while maintaining the compound’s native structure. This form allows for extended stability when stored properly.

Recommended Storage Conditions:

• Store lyophilized powder at -20°C (-4°F) or below for long-term preservation

• Protect from light exposure by keeping in original amber vial or dark storage

• Keep desiccated to prevent moisture absorption

• Allow vial to reach room temperature before opening to avoid condensation

Stability Considerations:
Peptides containing sulfur atoms can be more susceptible to oxidation than those without. For this reason, minimizing air exposure and avoiding repeated opening of stock vials is particularly important for TESA 10MG. Consider aliquoting reconstituted material under inert gas if extended storage is required.

Once reconstituted with an appropriate sterile solvent, the solution should be used immediately or stored according to standard laboratory protocols for oxidation-sensitive peptide handling.

Intended Use and Regulatory Status

Research Use Only

TESA 10MG is classified as a research chemical and is intended exclusively for laboratory and in vitro experimentation. This designation means the product is sold strictly for:

• In vitro testing — experiments conducted in controlled laboratory environments using test tubes, culture dishes, or similar apparatus

• Analytical research — chemical analysis and characterization studies

• Scientific investigation — basic research into peptide structure, function, and properties

• Cell culture studies — investigating peptide interactions with cellular systems in controlled environments

Important Regulatory Notice

This product is not a drug, food, cosmetic, or medical device. Bodily introduction of any kind into humans or animals is strictly forbidden by law. The product should only be handled by licensed, qualified professionals working in appropriate laboratory facilities.

The supplier is a chemical supplier, not a compounding pharmacy or outsourcing facility under Sections 503A or 503B of the Federal Food, Drug, and Cosmetic Act. All product information provided is for educational purposes only and does not constitute medical advice or clinical recommendations.

Handling and Safety Guidelines

Professional Handling Required

TESA 10MG should only be handled by trained laboratory personnel wearing appropriate personal protective equipment (PPE), including:

• Laboratory coat

• Nitrile gloves — check for compatibility if using organic solvents

• Safety goggles or face shield

• Appropriate respiratory protection if aerosolization is possible

Reconstitution Protocol

For laboratory use, the lyophilized powder should be reconstituted with a sterile, compatible solvent. Standard practice includes:

1. Allow the sealed vial to reach room temperature — approximately 15-30 minutes

2. Clean the rubber stopper with an alcohol swab

3. Add the calculated volume of solvent to achieve desired concentration

4. Gently swirl or roll the vial between palms — do not shake vigorously to avoid foaming and denaturation

5. Allow complete dissolution before use — this may take several minutes

Reconstitution Example for TESA 10MG:
For researchers needing a 5mg/mL working solution, add 2mL of sterile solvent to the 10mg vial. For a 10mg/mL solution, add 1mL of solvent. For a 2mg/mL solution, add 5mL of solvent. Always verify calculations before proceeding with experiments.

Disposal Considerations

Dispose of TESA 10MG and any contaminated materials in accordance with federal, state, and local regulations for chemical waste disposal. Do not dispose of in regular trash or down drains unless permitted by local guidelines.

Research Applications

TESA 10MG is used in various laboratory research contexts. Typical applications include:

• Receptor binding studies — investigating peptide-receptor interactions

• Signal transduction research — examining cellular response pathways

• In vitro efficacy studies — evaluating biological activity in controlled systems

• Structure-activity relationship (SAR) analysis — understanding how peptide structure affects function

Researchers should design their experimental protocols based on peer-reviewed literature and established laboratory practices specific to this class of peptides.

What Makes This Product Different

Rigorous Quality Control

Unlike research chemicals sold without verification, TESA 10MG comes with documented third-party testing for every batch. This commitment to quality assurance gives researchers confidence in the consistency and reliability of their experimental results.

Complete Documentation

Each product listing includes full chemical specifications, including molecular formula, molecular mass, and CAS number. This transparency allows researchers to verify the exact compound they are working with.

Appropriate Packaging for Sensitive Peptides

The sealed, sterile vial packaging protects the lyophilized powder from environmental contaminants. The 10mg concentration is particularly useful for experiments requiring precise, smaller-scale handling, reducing waste for preliminary or pilot studies.

Batch Traceability

Each package of TESA 10MG includes batch identification numbers that allow researchers to trace their material back to original manufacturing and testing records. This traceability is essential for reproducible research and quality documentation.

Frequently Asked Questions for Researchers

What is the purity level of TESA 10MG?

Each batch is tested to verify purity exceeding 99%. Individual certificates of analysis are available upon request.

How should the lyophilized powder be stored?

Store at -20°C or below, protected from light and moisture. Due to the presence of sulfur in the molecular structure, minimizing air exposure is particularly important.

What solvent should be used for reconstitution?

Researchers should determine the appropriate solvent based on their specific experimental protocol. Common options include sterile water for injection, bacteriostatic water, or buffered solutions. The choice of solvent may affect peptide stability.

Is this product sterile?

The lyophilized powder is manufactured under aseptic conditions, but researchers should follow standard laboratory practices for handling research chemicals. For cell culture applications, additional filtration may be appropriate.

How does TESA 10MG differ from other research peptides?

TESA 10MG has a unique molecular formula (C₂₂₁H₃₇₆N₇₂O₆₈S) and molecular mass (4947.61) that distinguish it from other research peptides. Researchers should verify the CAS number (1000157-72-1) when selecting compounds for specific experimental protocols.

Can TESA 10MG be used in combination with other research peptides?

Researchers should determine compatibility based on their specific experimental design. Standard laboratory practice includes testing interactions in control experiments before full-scale implementation.
