SNCA Protein, Human

Cat. No.: HY-P70577
COA Handling Instructions

Alpha-synuclein (SNCA) is a key neuronal protein that regulates synaptic activity, including vesicle transport and neurotransmitter release. As a monomer, it enhances vesicle exocytosis, promotes fusion and fusion pore expansion, and increases local Ca(2+) release. SNCA Protein, Human is the recombinant human-derived SNCA protein, expressed by E. coli , with tag free. The total length of SNCA Protein, Human is 140 a.a., with molecular weight of ~17.0 kDa.

Background

alpha-Synuclein (SNCA), a pivotal neuronal protein, orchestrates diverse roles in synaptic activity, including the regulation of synaptic vesicle trafficking and neurotransmitter release. As a monomer, it actively participates in synaptic vesicle exocytosis, enhancing vesicle priming, fusion, and dilation of exocytotic fusion pores, and mechanistically increases local Ca(2+) release from microdomains, crucial for ATP-induced exocytosis. In its multimeric membrane-bound state, SNCA functions as a molecular chaperone, assisting in the folding of synaptic fusion components (SNAREs) at the presynaptic plasma membrane, a process vital for maintaining normal SNARE-complex assembly during aging. SNCA also plays a crucial role in regulating dopamine neurotransmission by interacting with the dopamine transporter (DAT1) and modulating its activity. Existing as both a soluble monomer and homotetramer, a dynamic intracellular population of tetramers and monomers coexists, with the tetramer playing an essential role in maintaining homeostasis. SNCA engages in a complex network of interactions with proteins such as UCHL1, synphilin-1/SNCAIP, CALM1, STXBP1, VAMP2, SNAP25, RPH3A, RAB3A, SERF1A, and SEPTIN4, highlighting its involvement in intricate molecular processes governing synaptic function and integrity.

Molecular Weight

Approximately 17.0 kDa

Purity

Greater than 95% as determined by reducing SDS-PAGE.

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.

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.

  • Reconstitution Calculator

  • 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
