Product Introduction

IGF-1LR3 Chemical Product Introduction

IGF-1LR3, short for - like Growth Factor 1 Long Arginine 3, is a synthetic and modified version of - like growth factor 1 (IGF - 1). This peptide has been engineered to have unique properties that set it apart from its natural counterpart.

Structural Modifications

IGF - 1LR3 contains 83 amino acids. It has an extra 13 amino acids added to the N - terminus of the IGF - 1 molecule. Moreover, the third amino acid glutamic acid (E) in IGF - 1 is replaced with arginine (R), which is why it is named R3. These changes result in a molecular formula of C₄₀₀H₆₂₅N₁₁₁O₁₁₅S₉ and a molecular weight of approximately 9117.5 g/mol.

Enhanced Biological Activity

Compared to unmodified IGF - 1, IGF - 1LR3 has a much longer half - life, lasting about 20 - 30 hours in the body, while IGF - 1's half - life is only around 12 - 15 hours. This is because IGF - 1LR3 has a very low affinity for - like growth factor - binding proteins (IGF - BPs), allowing it to remain active in the bloodstream for an extended period. As a result, it is roughly three times more potent than IGF - 1.

Mechanism of Action

IGF - 1LR3 binds to specific cell receptors, such as the IGF - 1 receptor on muscle cells. This binding activates intracellular signal transduction pathways, most notably the AKT signaling pathway. Once activated, it stimulates cell growth and proliferation, promotes muscle repair, and inhibits cell apoptosis. It also plays a role in regulating fat metabolism by facilitating fat burning and utilization for energy production.

Potential Applications

In research, IGF - 1LR3 shows promise in stem cell research and cell manufacturing, especially for cells of the ectoderm lineage (like oligodendrocytes and motor neurons) and mesoderm lineage (such as osteocytes, chondrocytes, and muscle cells). It may also have potential applications in sports science for muscle growth and recovery, and in medicine for treating muscle - wasting diseases, although further studies are needed to fully understand its safety and efficacy in these areas.

Physical Properties

Typically, IGF - 1LR3 comes in the form of a fine white lyophilized powder. It can be dissolved in a 100 μg/ml sterile diluent, such as distilled de - ionized water. When stored as a lyophilized protein, it should be kept at - 20 °C. After reconstitution, it is advisable to aliquot it into several vials to avoid repeated freezing and thawing, and the reconstituted protein can be stored at 4 °C.

ECHEMI Editorial Reference

Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1). It differs from native IGF-1 in that it possesses an arginine instead of a glutamic acid at the third position in its amino acid sequence ("arginine 3"), and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN) ("long"), for a total of 83 amino acids (relative to the 70 of IGF-1).
