Buy DSIP in Australia from Macropus Peptides in two priced lyophilised strengths, 5mg and 10mg. DSIP, delta sleep-inducing peptide, is a nine amino acid neuropeptide first isolated from rabbit blood and reported in 1977, and it remains a research compound whose gene and receptor have never been identified. Laboratories use it in EEG, neuroendocrine and stress-axis studies in animal models. Both vials can be ordered now, and the 10mg fill also comes inside a starter kit with diluent and consumables. Every sealed vial carries compound, strength, lot number and storage temperature, and a certificate of analysis is available for each lot. Add bacteriostatic water for reconstitution and your order ships from Australia to any address in the country. DSIP for sale to adults for in-vitro laboratory research only, not for human or veterinary use.

Buy DSIP Australia: 5mg and 10mg Vials

Macropus Peptides supplies this nonapeptide to Australian laboratories as freeze-dried powder in two priced strengths, 5mg and 10mg, ready to ship. Both fills come from a single synthesis run with its own lot code, so switching strength changes only the amount of peptide in the glass. A starter kit with the same vial, diluent and consumables is listed alongside it.

DSIP peptide Australia: what the nonapeptide is

DSIP abbreviates delta sleep-inducing peptide, a label that records how it was found rather than a settled function. It is a linear chain of nine amino acids, Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, with no disulfide bridge or unusual residues, which makes it one of the simplest neuropeptides in research use. It was isolated in Switzerland from the cerebral venous blood of rabbits during electrically evoked slow-wave EEG activity, and characterised in PNAS in 1977. Nearly fifty years later, neither a gene coding for it nor a dedicated receptor has been confirmed, and it has no approved use anywhere.

How does DSIP work: the peptide in research

Because no receptor is known, the nonapeptide is studied by what it does in a model rather than by where it binds. Early work recorded EEG delta activity in rabbits and other animals after administration. Later studies turned to the neuroendocrine system, measuring corticotropin and other pituitary hormones, and to stress responses. Immunoreactivity resembling it has been reported in the hypothalamus, pituitary, peripheral organs and plasma. One line of work found that antibodies raised against it also recognise a separate protein, the glucocorticoid-induced leucine zipper, which shares an epitope but is not its precursor. Findings differ between models and laboratories, and that uncertainty is exactly why the peptide is still ordered as an investigational probe.

DSIP research: what the studies show

The record begins with the 1977 PNAS paper describing isolation, amino acid sequence and EEG activity of the peptide in rabbits. Neuroscience and Biobehavioral Reviews published a review in 1984 covering its chemistry, tissue distribution and the physiological actions reported up to then. In 2006 the Journal of Neurochemistry reassessed the field under the title of a still unresolved riddle, setting out the missing gene, the missing receptor and the conflicting results. The literature is mostly animal work and short reviews, with few recent controlled studies. For each paper's model and measured endpoints, open the DSIP research studies library.

DSIP peptide vial specifications

Each vial contains the nonapeptide as a fluffy white lyophilised cake, molecular weight roughly 849 g/mol, sealed with a stopper and crimp cap. The label gives compound, strength in milligrams, lot code and a frozen storage temperature. The tryptophan at the start of the chain is sensitive to light, so the vial should stay in its box in the freezer until use. Your certificate of analysis is issued against that lot. With an aspartic acid, a glutamic acid and a free carboxyl end against a single amino terminus, the chain carries a net negative charge at neutral pH and dissolves readily in bacteriostatic water.

DSIP peptide price in Australia: 5mg and 10mg

Both fills carry a list price and can be bought online now. Moving up from 5mg to 10mg doubles the nonapeptide but adds only a little over half to the price, which makes the larger fill cheaper per milligram; the smaller fill wins on outlay when a pilot is all that is planned. The DSIP starter kit costs a little more than the bare vial and adds a diluent vial plus the syringes and swabs for preparing it on arrival, which suits a first order or a lab without consumables on the shelf.

DSIP 10mg: the vial to order

Buyers searching for this peptide mostly want the 10mg fill. It holds enough to take an EEG, hormone or cell series from pilot to replicates on one lot. A 2 mL addition of bacteriostatic water leaves the nonapeptide at 5 mg/mL; a 5 mL addition leaves it at 2 mg/mL. At 2 mg/mL the vial splits into fifty 0.1 mL portions of 200 micrograms, so one lot can serve a long series without the stock being warmed twice. Kit buyers receive the vial with a 3 mL water vial, ten syringes of 0.5 mL capacity and twenty swabs.

DSIP 5mg: the mid-size vial for defined studies

Half the larger vial, for a defined study that will not use 10mg within the stability window of a mixed solution. Diluted with 2.5 mL, this fill lands on 2 mg/mL, matching the 10mg vial taken up in 5 mL, so pipetting plans carry across; with 1 mL it gives 5 mg/mL. Smaller stocks also mean less light-sensitive tryptophan sitting in solution between runs.

• Quote the lot on the label to receive its certificate

How to mix DSIP peptide: reconstitution and calculator

Let the diluent trickle down the glass, then swirl rather than shake. Concentration is milligrams over millilitres:

• 10mg plus 1 mL: 10 mg/mL
• 10mg plus 2 mL: 5 mg/mL
• 10mg plus 4 mL: 2.5 mg/mL
• 10mg plus 5 mL: 2 mg/mL
• 5mg plus 1 mL: 5 mg/mL
• 5mg plus 2.5 mL: 2 mg/mL

Protocols written in molar units can use roughly 5.9 millimolar for a 5 mg/mL stock, falling to about 5.9 micromolar after a thousandfold dilution, once the counter-ion stated on the certificate has been allowed for. For in-between volumes, the peptide calculator on the listing gives the answer in mg/mL and mcg/mL. Bacteriostatic water 10mL ships in the same parcel, and more diluents are in lab supplies.

Is DSIP available in Australia

It is available as a research chemical and nothing more. Australian regulators have never listed the nonapeptide on the ARTG or approved it, and it may not be given to people or animals, which is why our release is limited to in-vitro study. The Poisons Standard governs scheduling and is revised periodically, so confirm its current wording for your laboratory before ordering.

DSIP for sale Australia wide: neuropeptide delivery

From Townsville to Launceston, sleep and neuroendocrine laboratories receive vials dispatched from Australian stock, in capitals and regional centres alike. Neuropeptide groups commonly combine this vial with Selank, Epitalon or the starter kit, and our wider longevity and cognitive range sits beside it.
