Frequently asked questions

No. Ember catalogue materials are presented for in-vitro laboratory and analytical research only. They are not approved or intended for human, veterinary, cosmetic, or therapeutic use. Research-use labelling does not establish safety, efficacy, sterility, or legal authorization, and support cannot provide medical advice or human-use instructions.

Requirements vary by jurisdiction, compound, institution, and intended work. Do not assume that a research-use label removes licensing, import, controlled-material, or institutional requirements. Confirm eligibility with your qualified legal, ethics, or compliance lead before ordering; support cannot determine it for you.

Each product page outlines the compound, available amounts, pricing, and the research context currently published for it. Product information does not convert preclinical or in-vitro findings into a clinical claim.

Research sets group individual compounds around a shared research theme. The included products and amounts are listed on every set page.

Where a batch or sample report is available, analytical methods such as RP-HPLC can report chromatographic purity and related peaks, while LC-MS can support molecular-identity analysis. Review the method, sample identity, report date, acceptance criteria, and limitations. A percentage alone is not proof of sterility, potency, or human safety.

Match the product name, exact lot or laboratory sample ID, report number, test date, provider, methods, and any verification code to the vial and published record. Read the chromatogram and stated limits together. A generic or unmatched COA should not be treated as evidence for your unit.

Purity describes the target sequence relative to detected impurities under a stated analytical method. Net peptide content is a mass-accounting measure that may distinguish peptide from counter-ions, residual water, or declared excipients. Both depend on the method and report scope; neither alone establishes assay suitability or clinical safety.

Endotoxins are lipopolysaccharides associated with the outer membrane of certain bacteria. An endotoxin result indicates whether a sample met the stated test limit under that method. It is not the same as a sterility test and does not make a research material safe for injection or human use.

A range or plus sign usually communicates a minimum or rounded pass threshold, while a value such as 99.24% reflects quantified peak integration under a particular method. Compare results only when the method, sample, acceptance criteria, and reporting basis are clear.

A published analytical record describes only the identified sample and the tests performed on it. Match the identifier on the vial, label, or verification record before relying on the document, and do not transfer its result to another unit, lot, or batch.

Manufacturing routes vary. Many synthetic peptides are assembled by solid-phase peptide synthesis (SPPS), while liquid-phase or hybrid workflows may be used for other sequences. The route alone does not establish identity, purity, or assay performance; request process details when they are important to your work.

Use the lot-specific label, SDS, and validated laboratory instructions. In general, keep sealed dry material protected from moisture, light, and heat under the stated cold-storage condition. Do not treat a 12–36 month shelf-life claim or a -20°C recommendation as universal unless product-specific stability data support it.

There is no universal 2–8 week rule. Post-reconstitution stability depends on the sequence, formulation, container, solvent, concentration, temperature, and handling. Use only a validated, product-specific laboratory protocol, and do not store a reconstituted solution unless its documentation permits it.

Avoid refreezing and repeated freeze–thaw cycles unless product-specific stability data and your laboratory SOP explicitly allow them. When the handling history is uncertain, hold the sample and ask a qualified lab lead how to proceed.

Ambient transit does not by itself prove that dry lyophilized material is unusable, but stability after a temperature excursion cannot be confirmed from appearance alone. Record the delivery condition, timing, and lot information, then contact support before testing if the product may have been compromised.

Lyophilization behavior, sequence, container conditions, and any declared excipients can change the size and shape of a dry plug. Physical appearance is not a measurement of purity or active mass; rely on the labelled content and matched analytical record.

Use the solvent specified by the product documentation and your laboratory's validated SOP. Bacteriostatic water contains a preservative, but it is not a universal research diluent and does not make a product sterile or suitable for human use. Vehicle compatibility is compound- and method-specific.

Do not improvise with acids, bases, or DMSO. Solubility is compound- and formulation-specific; check product documentation or ask a qualified laboratory lead. If the sample remains particulate or cloudy, pause the work until it has been assessed.

For an in-vitro solution, concentration is mass divided by final volume. For example, 5 mg in 2 mL equals 2.5 mg/mL. Use the active or net-content definition stated by the analytical record and keep units consistent. This arithmetic is not a dosing or administration protocol.

Sealed lyophilized vials can have a pressure difference after processing. Treat it as a handling signal, not a prompt to improvise syringe technique; follow your institution's SOP and the product documentation.

Do not use or continue the assay until qualified laboratory personnel assess it. Cloudiness, particulates, or discoloration may reflect insolubility, aggregation, contamination, or degradation. Do not try to rescue the solution with unvalidated pH changes or solvents.

Follow the exact manufacturer's label and your laboratory SOP. A blanket 28-day rule should not be applied to every product or use; discard the vial if the closure is compromised, contamination is suspected, or the labelled in-use period has elapsed.

Canadian orders can be paid by Interac e-Transfer or cryptocurrency. U.S. orders can be paid by cryptocurrency. Available methods are shown at checkout; use only the payment instructions shown there or in an official order message.

Payment providers may restrict research-chemical transactions, so card availability can vary by destination and provider. If a card option is not displayed at checkout, use only another method currently offered there.

Packaging, shipping origin, import documentation, duties, and border review depend on the destination and fulfilment route. Do not assume inspection-free delivery, seizure-free transit, or a particular packaging format; review the current shipping terms and applicable import requirements before ordering.

Available services, charges, and estimated transit times are shown during checkout for supported Canadian destinations.

Include your order number and a short description of the issue. Support may request photographs for damaged or incorrect orders.

Return eligibility depends on product condition, handling requirements, and the policy presented at checkout. Do not send an item back before support reviews the request, because chain-of-custody and storage conditions cannot be verified after delivery.
