Semaphorin-3A/SEMA3A Protein, Human (HEK293, N-His)
Based on 1 Customer Validation
Semaphorin-3A/SEMA3A proteins are critical for shaping the olfactory system and influence puberty-related neuronal control. SEMA3A is known for inducing neuronal growth cone collapse, which leads to the formation of complex neuronal circuits by guiding the growth cone through a motor inhibitory mechanism. Semaphorin-3A/SEMA3A Protein, Human (HEK293, N-His) is the recombinant human-derived Semaphorin-3A/SEMA3A protein, expressed by HEK293 , with N-6*His labeled tag.
- Species: Human
- Source: HEK293

Description
Semaphorin-3A/SEMA3A proteins are critical for shaping the olfactory system and influence puberty-related neuronal control. SEMA3A is known for inducing neuronal growth cone collapse, which leads to the formation of complex neuronal circuits by guiding the growth cone through a motor inhibitory mechanism. Semaphorin-3A/SEMA3A Protein, Human (HEK293, N-His) is the recombinant human-derived Semaphorin-3A/SEMA3A protein, expressed by HEK293 , with N-6*His labeled tag.
Background
The Semaphorin-3A/SEMA3A Protein plays a crucial role in the development of the olfactory system and exerts influence over neuronal control of puberty. Known for its capacity to induce the collapse and paralysis of neuronal growth cones, SEMA3A is implicated in guiding specific growth cones through a motility-inhibiting mechanism, thereby contributing to the intricacies of neuronal circuit formation. This protein serves as a ligand by binding to the complex neuropilin-1/plexin-1, underscoring its involvement in transducing signaling cues critical for neuronal guidance. Additionally, SEMA3A interacts with PLXND1, further highlighting its multifaceted role in mediating cellular interactions during the intricate processes of olfactory system development and the regulation of puberty-related neuronal functions.
Verified Bioactivity
1.Measured by its binding ability in a functional ELISA. Immobilized Recombinant Rat Neuropilin-1 (HY-P702534) is immobilized at 2 µg/mL (100 µL/well) can bind Biotinylated Recombinant Human SEMA3A. The ED50 for this effect is 100-300 ng/mL.
2.Measured by its binding ability in a functional ELISA. Immobilized Human SEMA3A at 2 μg/mL (100 μL/well) can bind Human Neuropilin-1 (HY-P78779). The ED50 for this effect is 0.315 μg/mL.
