DSIP in brief
DSIP comes in 3 strengths from 2mg to 15mg per vial, each a sealed box of ten, from $24.60 to $64.41 a box. Per mg the spread is wide: DS15 (15mg x 10 vials) works out at $0.429 per mg against $1.230 per mg for DS2 (2mg x 10 vials), 65 percent less for the same mg, because the vial, the fill and the testing cost about the same whatever the vial holds.
One of the 3 strengths is on the shelf today (DS5) and leaves in 1 to 2 business days after payment clears; DS5 is running low. DS2 and DS15 are made to order, about four weeks.
What DSIP is
DSIP, delta sleep-inducing peptide, is a nonapeptide, WAGGDASGE, average mass 848.8, first isolated from rabbit and made synthetically since. It begins with a tryptophan, has an acidic C-terminal half with an aspartate at 5 and a glutamate at 9, and contains one Asp-Ala pair and a Gly-Gly stretch that make it flexible.
The N-terminal tryptophan is the residue that ages, oxidising under light. There is no methionine and nothing to deamidate. It is a strongly hydrophilic, acidic chain that dissolves instantly. Store dark.
Registry and identity
- WHO Proposed INN List 70 gave DSIP the name emideltide, and FDA's GSRS files it under UNII YN28Z5YZ73, CAS 62568-57-4, ChEMBL CHEMBL2104403, Merck Index m4775 and PubChem CID 68816. FDA GSRS
- A second CAS number, 69431-45-4, sits on the same GSRS record, flagged as given with no structure. FDA GSRS
- An N-acetylated form is filed separately as N-acetyl emideltide (UNII CL985USD2K), Ac-WAGGDASGE, which worked from the sequence is C37H50N10O16, average mass 890.9, the 890.85 that the record's validation note calculates: DSIP's 848.8 plus one acetyl group. FDA GSRS, PubChem
- Tryptophan 1 is the chain's only aromatic residue and gives it its absorbance at 280 nm; at high resolution [M+H]+ is at m/z 849.337 and [M+2H]2+ at 425.172, from a monoisotopic mass of 848.330 worked from C35H48N10O15 with NIST isotope masses. FDA GSRS, PubChem, NIST

DSIP beside Epithalon and Selank
DSIP works out at $0.429 per mg at 15mg (DS15), its lowest by the single box. Its neighbours, on price alone: Epithalon at $0.468 per mg at 50mg (ET50), 390.4 g/mol; Selank at $0.740 per mg at 10mg (SK10), 751.9 g/mol.
Reading a DSIP certificate of analysis (COA)
Identity by mass. Average mass 848.8 (C35H48N10O15). In electrospray the protonated ions come near m/z 849.8 (singly charged), m/z 425.4 (doubly charged); on our certificates the measured mass is matched to the calculated average mass, within about one unit.
- Oxidation: 1 tryptophan, which oxidises to kynurenine and hydroxy forms under light. Kynurenine makes the chain 4 heavier and a hydroxy tryptophan 16.
- Deamidation: no asparagine or glutamine, so the +1 mass deamidation impurity common in longer peptides does not apply.
- Charge: near neutral pH about -2, acidic.

Questions about DSIP
What gives DSIP its charge of about -2?
Its two acidic side chains, with no basic one to offset them: the aspartate in fifth place and the glutamate that ends the chain are each negative near neutral pH, and DSIP holds no lysine, arginine or histidine. Both ends are free, so the amine on tryptophan 1 and the final carboxyl cancel each other. The rest, the tryptophan, three glycines, two alanines and a serine, carry no charge.
How much does DSIP cost?
From $24.60 a sealed box of 10 vials, up to $64.41 for the largest strength sold singly, which works out at $0.429 per mg at its best-priced size. DS2, the cheapest box sold singly, is made to order, about four weeks; the cheapest on the shelf is DS5 at $44.20. 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 DSIP size is cheapest per mg?
DS15, 15mg x 10 vials, at $0.429 per mg, which is 65 percent less per mg than DS2, at $1.230 per mg. Larger vials cost less per mg across this range, so match the vial to the size of the work first, then compare per mg.
Can I buy a single vial of DSIP?
No. One sealed box of ten vials is the smallest quantity of a regular line; for DSIP that is DS2, 2mg x 10 vials, at $24.60. A first order must reach $100 of goods, so DS2 alone takes five boxes ($123.00) or one box beside other lines. 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 DSIP strengths are in stock today?
DS5 at $44.20 a box (running low). DS2 and DS15 are made to order, about four weeks.
How is DSIP 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 DSIP?
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. DSIP 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 DSIP?
Yes. For DSIP 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.
