Product Details:

Properties IGF-1 LR3 (Long R3 Insulin-like Growth Factor-I) is an engineered, recombinant analogue of naturally occurring insulin-like growth factor-1 (IGF-1). Key Structural Characteristics Amino Acid Structure: It features an extension of 13 amino acids at the N-terminus of the native IGF-1 molecule, with the glutamic acid at position 3 replaced by arginine (Arg). It consists of a total of 83 amino acids (with a molecular weight of approximately 9.1 kDa). Reduced Binding Affinity: Due to these structural modifications, its affinity for IGF-binding proteins (IGFBPs) is significantly reduced to only a small percentage (or even less) of that of native IGF-1. Extended Duration of Action: Because it is not rapidly inactivated or cleared by binding proteins, its half-life in the body is substantially prolonged, leading to significantly enhanced biological activity. Primary Biological Properties Receptor Binding: It exhibits high affinity for the IGF-1 receptor (IGF-IR) and potently activates the downstream AKT signaling pathway. Promotion of Growth and Proliferation: It possesses a robust capacity to stimulate cell growth, differentiation, and protein synthesis, while also inhibiting apoptosis (programmed cell death). Tissue and Metabolic Effects: It promotes muscle growth and repair, supports the repair and regeneration of nerve cells, stimulates fibrous tissue proliferation, and contributes to some extent to energy utilization and fat loss. Applications: In scientific research and biotechnology, it is frequently used as a highly effective additive in serum-free cell culture media to facilitate the production of recombinant proteins and enhance cell proliferation.

China NAD+ 100mg/500mg/1000mg Price : 5.0 USD ($)/Piece Minimum Order Quantity : 10 Grade : Research Grade Product Type : Peptides Properties : 1. Core Components of Basic Chemistry and Physiology: NAD+ is composed of one nicotinamide nucleotide and one adenine nucleotide linked by a pyrophosphate bond. Redox State: NAD+ is in its oxidized form; when it accepts two electrons and a proton (hydrogen ion), it is converted to its reduced form (NADH). This interconversion of redox pairs is fundamental to energy production in organisms. Wide Distribution: As an endogenous substance, it naturally exists in every cell of the human body, mediating thousands of biochemical reactions. 2. Biological Functions: Energy Metabolism Hub: It participates in cellular respiration and is a key mediator in glycolysis, the tricarboxylic acid cycle (TCA), and the electron transport chain (respiratory chain), responsible for converting nutrients into cellular energy (ATP). DNA Repair: It is a substrate and activator of DNA repair enzymes (such as PARP), helping to repair DNA damage caused by ultraviolet radiation or oxidative stress. Activation of Longevity Proteins: As a key linker, NAD+ can activate longevity genes (Sirtuins, such as SIRT1SIRT7), thereby regulating cellular senescence, inflammatory responses, and metabolic homeostasis. 3. Dynamic Consumption with Age: In a healthy state, the body's NAD+ concentration is in dynamic equilibrium. However, with age or prolonged exposure to highpressure, unhealthy lifestyles, NAD+ synthesis decreases while consumption increases, leading to a significant decline in overall concentration. This is considered one of the important contributing factors to aging. 4. Clinical and Healthcare Applications for Antiaging and Vitality Enhancement: Due to its ability to improve mitochondrial function and promote cell repair, it is often used to delay aging, alleviate mental fatigue, improve memory, and enhance physical strength. Solubility : Soluble in water CAS No : 53849 Usage : Boost Cellular Energy: As an "energy transmitter," it helps mitochondria convert food into ATP (acetylene trioxide), improving chronic fatigue and enhancing physical strength and energy. Initiate Cellular Repair: It activates "sirtuins" in the body, repairing damaged DNA and maintaining genome stability. Improve Brain Function: Providing ample energy to brain cells helps enhance memory, improve concentration, and alleviate brain fog. Regulate Biological Clock: It helps regulate the body's circadian rhythm, improving sleep quality. AntiAging and Skin Beautification: It promotes metabolism, combats oxidative stress, reduces skin blemishes, and improves skin elasticity and hydration.
