Insulin: price, documentation and dispatch in Colombia
Insulin comes in a 3 ml vial, from US$291. It is one of the few catalog references described as a two-chain protein joined by disulfide bridges, a molecular architecture different from the single-chain peptides that dominate the rest of the catalog. It belongs to the classic hormones and essential cofactors category, alongside references as different from one another as erythropoietin or glutathione. This page organizes identification, liquid presentation, price, lot certificate issued by Janoshik Analytical, and purchase conditions, strictly within the framework of research and laboratory work.

A two-chain architecture, not a single chain
The published classification describes Insulin as a two-chain protein joined by disulfide bridges. It is one of the few catalog references with that architecture: most are single-chain peptides of varying length. Two chains held together by disulfide bonds is a more complex structure than a simple linear peptide, and that difference is stated in the catalog's technical classification.
Within the classic hormones and essential cofactors category, that structural complexity sets Insulin apart even from the catalog's own erythropoietin (EPO), described as a 165-amino-acid single-chain glycoprotein, and even more so from oxytocin, a cyclic nine-amino-acid nonapeptide, or glutathione, a tripeptide of just three.
A presentation in milliliters: what to state in the quote
The catalog offers Insulin in a single format: 3 ml vial, with a current listed price from US$291. Unlike most catalog references, which come in milligrams per powder vial, Insulin is stated directly by volume, the same as LC216, although the latter is expressed as a concentration (milligrams per milliliter) rather than a total volume.
Before approving payment, the purchasing institution checks that value directly in the commercial block: being a liquid presentation rather than a powder does not change the need to confirm it there, without assuming it matches another catalog reference.
Certificate of analysis per lot: what Janoshik Analytical confirms
An Insulin lot's identity is not confirmed by the structural classification published on this page, but by the certificate of analysis (COA) that Janoshik Analytical issues: high-performance liquid chromatography (HPLC) for purity and mass spectrometry (MS) for identity, that is, to confirm that the observed mass corresponds to the stated reference.
The COA is handled on request and subject to documentary availability, and it corresponds to the specific lot of the 3 ml vial being shipped. This page does not publish its own purity figure, CAS number, or molecular weight: for a two-chain protein, those analytical figures are particularly sensitive to the specific lot's documentation, and are not filled in by comparison with any other catalog reference.
Handling a liquid presentation, unlike a powder vial
The 3 ml Insulin vial is a solution, not a powder requiring prior preparation. That difference in physical form from most of the catalog's references — presented as powders — has logistics implications: the volume is measured directly, without the additional reconstitution step that a powder presentation requires.
The catalog's technical sheet states storage at 2–8 °C, protected from light, for the site's references overall; that condition should be confirmed against the specific documentation of the Insulin lot received. On arrival, it is worth verifying the vial's volume and the lot visible on the label, checking both against the accepted quote.
From the institutional quote to payment
Selecting Insulin in the catalog does not trigger an immediate charge. The institutional workflow first records the request with the 3 ml presentation and the current price; the commercial confirmation follows, fixing the total, the destination, and the payment method in writing. Shipping is calculated separately from the material's price, with rates for Bogotá and for the rest of the country shown on the site's shipping information. Outside Colombia, this reference ships to 5 countries (Costa Rica, Ecuador, United States, Mexico and Puerto Rico), from US$57; the rate for each country is listed on the site's international shipping page.
Because this is a liquid presentation rather than a powder, it is worth checking with particular care that the quote received states the volume (3 ml) precisely, the current price, and, if requested, the status of the COA, before authorizing payment and linking the proof of payment to the order code.
Insulin against its category peers: a hierarchy of complexity
Within the classic hormones and essential cofactors category, Insulin is the reference with the greatest declared structural complexity: a two-chain protein compared with erythropoietin's single-chain glycoprotein, oxytocin's cyclic nine-amino-acid peptide, or glutathione's tripeptide. It is a hierarchy of size and molecular architecture, nothing else.
That comparison — a two-chain protein against increasingly short single-chain peptides — is the one this page can support with the data already stated in the catalog's technical classification, without extending it to any conclusion about how each reference is used.
Frequently asked questions about Insulin
What presentation and price does Insulin have in the catalog?
3 ml vial, with a current listed price from US$291, the figure that governs the institutional quote.
What does "two-chain protein joined by disulfide bridges" mean?
It is the published structural classification: two amino acid chains held together by disulfide bonds, a more complex architecture than a single-chain peptide like most of the rest of the catalog.
How is the purity of an Insulin lot confirmed?
With the certificate of analysis (COA) from Janoshik Analytical: HPLC for purity and mass spectrometry for identity, per lot, on request and subject to documentary availability.
Does Insulin come as a powder or a solution?
As a solution: the 3 ml vial is measured directly by volume, unlike most catalog references, which come as a powder.
How much does shipping cost for an order with Insulin?
Rates for Bogotá and for the rest of the country are shown on the site's shipping information, with delivery time confirmed during the institutional quote. Outside Colombia, this reference ships to 5 countries (Costa Rica, Ecuador, United States, Mexico and Puerto Rico), from US$57; the rate for each country is listed on the site's international shipping page.
