SNAP-8 in brief
SNAP-8 comes in 2 strengths, 10mg and 100mg per vial, each a sealed box of ten: NP810 at $56.54 by the single box, NP8100 at $436.00 in 50-box lots.
Nothing is on the shelf today. NP810 is made to order, about four weeks, in any quantity. NP8100 is special order: brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
What SNAP-8 is
SNAP-8, acetyl octapeptide-3, is a synthetic eight-residue amide, Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2, average mass 1075.2, an extension by two residues of the hexapeptide acetyl hexapeptide-3. It is an acidic, hydrophilic chain with an acetylated N-terminus.
Its one methionine, at 3, oxidises to the sulfoxide, 16 heavier, and its glutamine, at 4, deamidates to glutamate, about 1 heavier, so those two forms are the related substances to expect. The two residues it adds to the hexapeptide, alanine and aspartate, end the chain, the aspartate as the C-terminal amide. It dissolves instantly.
SNAP-8 beside GHK-Cu and Glutathione
SNAP-8 works out at $0.565 per mg at 10mg (NP810), its lowest by the single box. Its neighbours: GHK-Cu at $0.052 per mg at 100mg (CU100), 401.9 g/mol, glycyl-histidyl-lysine bound to copper(II), with no methionine in it; Glutathione at $0.00359 per mg at 1500mg (GTT), 307.3 g/mol, a tripeptide whose one sulfur is a free thiol that pairs into GSSG, where SNAP-8’s is a methionine.
Reading a SNAP-8 certificate of analysis (COA)
Identity by mass. Average mass 1075.2 (C41H70N16O16S). In electrospray the protonated ions come near m/z 1076.2 (singly charged), m/z 538.6 (doubly charged); on our certificates the measured mass is matched to the calculated average mass, within about one unit.
- Oxidation: 1 methionine, which oxidises to the sulfoxide. The sulfoxide makes the chain 16 heavier.
- Deamidation: 1 glutamine. The deamidated form is 0.984 heavier and a little more negatively charged, inside the tolerance of the average-mass line; telling it apart takes a high-resolution mass, which the certificate does not carry.
- N-terminus: capped with an acetyl group, so there is no free N-terminal amine.
- Charge: near neutral pH about -1, acidic.

Questions about SNAP-8
Is acetyl octapeptide-3 the same as SNAP-8?
Yes. Acetyl octapeptide-3 and SNAP-8 are names for the same thing. Acetyl octapeptide-3 describes the line: an N-acetylated, C-amidated octapeptide from the N-terminal domain of SNAP-25. The certificate and the vial label carry SNAP-8, which is the name the batch is released under.
What are SNAP-8’s sequence, formula, molecular weight and CAS number?
Ac-EEMQRRAD-NH2, eight residues, acetylated at the N-terminus and amidated at the C-terminus: C41H70N16O16S, molecular weight (average mass) 1,075.2, CAS 868844-74-0.
Why does SNAP-8 carry a negative charge?
Its acidic residues, two glutamates, at 1 and 2, plus the aspartate at 8, outnumber its two arginines, at 5 and 6, and neither end adds a charge, the N-terminus being acetylated and the C-terminus an amide. That leaves it at -1 overall, with five of its eight residues charged.
What do SNAP-8’s last two residues add to the six-residue chain it extends?
Alanine at 7 and aspartate at 8, C7H10N2O4, which weighs about 186.2 of the chain’s 1,075.2, so the six-residue amide it extends, Ac-EEMQRR-NH2, comes to about 889.0, as C34H60N14O12S. SNAP-8’s sixteen nitrogens sit eight in the backbone, one in each residue, six in the two arginines’ side chains, one in the glutamine’s and one in the C-terminal amide, while the formula’s single S belongs to methionine 3.
How much does SNAP-8 cost?
From $56.54 a sealed box of 10 vials, which works out at $0.565 per mg at its best-priced size. NP8100 is special order, 50 boxes at least, at $436.00 a box. To a US address, freight is included from $1,000 of goods; below that it is the carrier’s rate for the carton or a flat $35.00, and to another country the desk quotes it; either way the figure is on the proforma before you pay. Every strength and its price per vial is in this page’s price table.
Which SNAP-8 size is cheapest per mg?
Of the sizes sold by the single box, NP810, 10mg x 10 vials, at $0.565 per mg. Sold only by special order, NP8100 is lower still, at $0.436 per mg, with a 50-box minimum.
Can I buy a single vial of SNAP-8?
No. One sealed box of ten vials is the smallest quantity of a regular line; for SNAP-8 that is NP810, 10mg x 10 vials, at $56.54. A first order must reach $100 of goods, so NP810 alone takes two boxes ($113.08) or one box beside other lines. NP8100 is special order and takes a minimum of 50 boxes. A box is sealed at fill with its batch number on it, and splitting one would break the link between the vials and their certificate.
Which SNAP-8 strengths are in stock today?
None today. NP810 is made to order, about four weeks, in any quantity. NP8100 is special order: brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
How is SNAP-8 stored?
At minus 20 degrees Celsius, dark and dry. Lyophilised powder tolerates a short spell at ambient temperature in transit, which is why boxes ship without ice. Storage and handling.
What is in a box of SNAP-8?
Ten sealed vials of one strength, each labelled with the product code, the strength and the batch number; the trade also calls a box a 10-vial kit. SNAP-8 is supplied as a powder in a sealed glass vial and in no other presentation. Boxes are not split.
Is a certificate of analysis (COA) provided for SNAP-8?
Yes. For SNAP-8 the batch certificate reports its purity, net content and identity by mass spectrometry. The other lines on this page are the specification it is made to, and the desk answers for them on a particular batch. The certificate is sent with the shipment, and again on request, and any batch number can be verified on the certificate page.
Is this for human use?
No. Everything here is supplied for laboratory research only, to trade accounts, and is not for human or animal consumption. The research-use page sets out who can buy and what is not sold.
