Semaphorin-3A/SEMA3A Protein, Human (HEK293, His-Flag)

Cat. No.: HY-P70797
COA Handling Instructions

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, His-Flag) is the recombinant human-derived Semaphorin-3A/SEMA3A protein, expressed by HEK293 , with N-6*His, N-Flag labeled tag. The total length of Semaphorin-3A/SEMA3A Protein, Human (HEK293, His-Flag) is 521 a.a., with molecular weight of 70-75 kDa.

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.

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
