Product Detail

1. Product Introduction

TB-500 BT5 is a synthetic polypeptide composed of 43 amino acid residues. The corresponding peptide sequence can be found in multiple mammalian cell types such as platelets and macrophages.

Laboratory research focuses on its binding characteristics with actin and related intracellular biological behaviors within cell model systems. All research results are limited to in-vitro laboratory environments.

This product is supplied as lyophilized powder for laboratory research only. It shall not be used for human administration, clinical trials or any medical application.

2. Structural & Characteristic Features

CAS No.:885340-08-9

Molecular Formula: C₃₈H₆₈N₁₀O₁₄

Molecular Weight:889.01

TB-500 BT5 adopts standardized solid-phase synthesis and HPLC purification process. The finished lyophilized powder possesses stable molecular structure and favorable water solubility.

Vacuum freeze-drying technology effectively slows molecular degradation and maintains molecular stability during transportation and low-temperature storage.

3. Main Research Application Directions

Only for laboratory in-vitro experimental research:

Basic research on binding interaction between polypeptide and actin protein
Exploration of polypeptide influence rules on cytoskeleton-related cell behaviors
Cell model experiment for research on polypeptide-mediated cell movement characteristics
Stability comparison research of long-chain synthetic polypeptide under different culture environments
Biochemical exploratory study of signal regulation related polypeptide molecular properties

4. Specifications & Quality Standard

Appearance: White or off-white lyophilized crystalline powder
Purity: ≥98% (HPLC high performance liquid chromatography detection)
Solubility: Freely soluble in sterile purified water and neutral PBS buffer
Moisture content: ≤2.0%
Quality control: Each batch provides complete COA test report, including HPLC purity detection and impurity screening
Batch stability: Mature synthesis & purification process ensures consistent quality among batches

5. Packaging & Storage Specifications

Conventional packaging: Vacuum lyophilized vial packaging; customized packaging supported for bulk orders
Packaging advantage: Aseptic sealed light-proof vial, moisture-proof, effectively prevent molecular inactivation
Storage requirement: Sealed storage at -20℃, protected from light and humidity; avoid repeated freezing and thawing
Shelf life: 24 months under specified low-temperature sealed storage

6. Applicable Scenarios

Suitable for university laboratories, biochemical research institutes, cell biology laboratories and polypeptide research groups, applied to basic cell and molecular experimental research.

Important Notice: For laboratory research use only. Not for human consumption or clinical trials.
