Animal-Free FGF-13 Protein, Human (His)

Cat. No.: HY-P700057AF
COA Handling Instructions

FGF-13 protein is a microtubule-binding protein that directly binds and stabilizes tubulin and affects microtubule polymerization. It exerts negative regulation on axonal and leading process branches, which are critical for neuronal polarization and migration in the cerebral cortex and hippocampus. Animal-Free FGF-13 Protein, Human (His) is the recombinant human-derived animal-FreeFGF-13 protein, expressed by E. coli , with C-His labeled tag. The total length of Animal-Free FGF-13 Protein, Human (His) is 245 a.a., with molecular weight of ~21.23 kDa.

Animal-free recombinant proteins offer high consistency and stability, whithout using or contacting of any animal-derived materials and reagents.

Description

FGF-13 protein is a microtubule-binding protein that directly binds and stabilizes tubulin and affects microtubule polymerization. It exerts negative regulation on axonal and leading process branches, which are critical for neuronal polarization and migration in the cerebral cortex and hippocampus. Animal-Free FGF-13 Protein, Human (His) is the recombinant human-derived animal-FreeFGF-13 protein, expressed by E. coli , with C-His labeled tag.

Background

FGF-13, a microtubule-binding protein, exerts direct interaction with tubulin, participating in both the polymerization and stabilization of microtubules. This engagement in microtubule dynamics suggests a role in the refinement of axons by negatively regulating branching of axonal and leading processes. Additionally, FGF-13 plays a crucial role in the polarization and migration of neurons within the cerebral cortex and hippocampus. It further regulates voltage-gated sodium channel transport and function, influencing the activity of specific sodium channel isoforms. Beyond its microtubule-related functions, FGF-13 is implicated in the development of axonal initial segment-targeting inhibitory GABAergic synapses facilitated by chandelier neurons. Through its diverse interactions, including those with various sodium channels and MAPK signaling components, FGF-13 emerges as a multifaceted player in the intricate regulatory network governing neuronal processes and synaptic 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
