Packing and freight

Freight is included on orders of £1,000.00 and over; below that the checkout quotes the carrier, or a flat £35.00 when no live quote is available, before you pay. The desk books the carrier. The packing list, commercial invoice and batch certificate travel with every shipment; ask for a packing specification if your receiving needs one.

Unit of sale	Sealed box of 10 vials. Boxes are not split.
Presentation	100mg x 10vials
Incoterm	DAP, delivered in the United Kingdom. Freight included on orders of £1,000.00 and over, quoted at checkout below that. Import VAT and duties, where they apply, are collected by the courier before delivery and are not in the price.

About this line

NP8100 is SNAP-8 at 100mg a vial: 10 sealed vials to the box, 1000 mg in total, £308.64 the box or £0.309 /mg. Of the 2 SNAP-8 sizes on the list it is the one that costs least per mg.

DAP, delivered in the United Kingdom, tracked, freight included on orders of £1,000.00 and over, quoted at checkout below that; delivery timing is confirmed when the order is acknowledged. 1 of the 2 sizes is held in stock now, 1 special order on a 50-box minimum; the ladder above marks each one. Every vial label repeats the code and the batch number, so the certificate can be pulled from the label alone.

At £308.64 a box, the 50-box minimum on NP8100 comes to £15,432.00 of goods, past the £300.00 GBP order minimum on its own. Below it on the ladder is NP810 (10mg x 10vials) at £0.389 /mg, 26 percent over this size.

What the certificate for NP8100 must show

Each box of NP8100 comes from one batch, and that batch’s certificate carries the lines below before it is released. The limits are the release specification; the sequence notes are worked out from the chain on the sheet.

Purity. Not less than 98.0 percent by RP-HPLC, area normalisation at 220 nm, with the main peak named on the chromatogram.
Identity. Retention time by RP-HPLC against the reference standard, confirmed by ESI-MS. The spectrometer should place the protonated molecule at m/z 1076.2 for 1+, m/z 538.6 for 2+, against a calculated average mass of 1075.2 (C41H70N16O16S); the measured mass should agree to within a unit.
Related substances. Any single related substance not more than 1.0 percent. On this sequence the ones to look for are the sulfoxide of the single methionine, sixteen mass units up and eluting ahead of the main peak and the deamidated chain, one mass unit up, from 1 glutamine.
Main peak position. On C18 the main peak comes early, on a shallow starting gradient; the backbone’s Kyte-Doolittle average is -2.41 over 8 residues and the net charge near neutral is about -1.
Terminus. The N-terminus is capped with an acetyl group; the chain ends in an amide, and the mass on the certificate includes it.
Water. Not more than 8.0 percent by Karl Fischer.
Fill. Labelled peptide content per vial, plus or minus 5 percent by weight.
Endotoxin. Reported on the certificate by LAL where the line is tested.
Batch, dates, signature. The batch number as printed on the vial label and the packing list, the date of manufacture, the retest date (24 months from manufacture at minus 20 degrees Celsius, retest date on every certificate), and the release signature.

Look up a batch number to pull the certificate on file; the signed copy travels with the shipment.

What is in a box of NP8100?

10 sealed vials, each holding 100mg of SNAP-8, 1000 mg in the box, packed as a lyophilised powder with the code, the strength and the batch number on every label. The box is the unit of sale and is not opened.

What is on the certificate for a batch of NP8100?

In order: purity, identity, related substances, main peak position, terminus, water, fill, endotoxin, batch, dates, signature. Each line carries its limit and the batch’s result; the list above is the whole of it, and the batch number on it matches the vial label.

How is NP8100 stored after delivery?

Minus 20 degrees Celsius, protected from light and moisture. Short transit at ambient is tolerated. Shelf life is 24 months from manufacture at minus 20 degrees Celsius, retest date on every certificate.

What is the smallest order of NP8100?

50 sealed boxes: NP8100 is a special order, brought in on a 50-box minimum. The order as a whole must reach £300.00 GBP (£100.00 on a first order), and any mix of lines counts toward it.

Does the NP8100 price come down with volume?

Yes, by the order and by the account, and checkout takes the better of the two, never both. A single order takes a volume discount on its goods: 5 percent from £5,000.00, 10 percent from £10,000.00, 15 percent from £20,000.00 and 20 percent from £50,000.00. Lifetime paid spend also moves the account up: Silver from £5,000.00 takes 3 percent off goods, Gold from £15,000.00 takes 6 percent off goods, Platinum from £50,000.00 takes 10 percent off goods, Diamond from £100,000.00 takes 15 percent off goods. On NP8100 that runs from £308.64 at list to £246.91 a box at 20 percent off.
