Ara-290 in brief

Ara-290 comes in 2 strengths from 10mg to 16mg per vial, each a sealed box of ten, from $80.87 to $115.31 a box. Per mg the spread is narrow: RA16 (16mg x 10 vials) works out at $0.721 per mg against $0.809 per mg for RA10 (10mg x 10 vials), 11 percent less for the same mg, because the vial, the fill and the testing cost about the same whatever the vial holds.

Nothing is held on the shelf: every strength is special order, brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.

What Ara-290 is

Ara-290, also called cibinetide, is an eleven-residue synthetic peptide whose sequence is taken from helix B of erythropoietin. It starts with a pyroglutamate, so there is no free N-terminal amine, and it has no cysteine, methionine or tryptophan. Average mass 1257.3.

What ages in it is the glutamine at position 3 and the asparagine near the C-terminus, which deamidate. It is a hydrophilic chain that dissolves easily. Identity on the certificate is the pyroglutamate form; a mass 17 units higher would be the chain whose first glutamine has not closed, and 18 higher one made from glutamate, either of them a synthesis impurity.

Ara-290 beside Thymosin Alpha-1

Ara-290 works out at $0.721 per mg at 16mg (RA16, in 50-box lots), its lowest. Its neighbour, on price alone: Thymosin Alpha-1 at $2.170 per mg at 10mg (TA10), 3,108.3 g/mol.

Reading an Ara-290 certificate of analysis (COA)

Identity by mass. Average mass 1257.3 (C51H84N16O21). In electrospray the protonated ions come near m/z 1258.3 (singly charged), m/z 629.7 (doubly charged); on our certificates the measured mass is matched to the calculated average mass, within about one unit.

  • Oxidation: no methionine, tryptophan or cysteine in the chain, so oxidised forms are not the impurity to expect.
  • Deamidation: 1 asparagine and 1 glutamine. The deamidated form is 0.984 heavier and a little more negatively charged, inside the tolerance of the average-mass line; telling it apart takes a high-resolution mass, which the certificate does not carry.
  • N-terminus: pyroglutamate, so there is no free amine at the start of the chain and no N-terminal degradation of the usual kind.
  • Charge: near neutral pH about -2, acidic.
  • The pyroglutamate is the identity; a chain whose first glutamine has not closed weighs 17 more, and one made from an open glutamate 18 more.

Questions about Ara-290

Is cibinetide the same as Ara-290?

Yes. Cibinetide and Ara-290 are names for the same thing. Cibinetide is Ara-290’s other name, for the eleven-residue peptide from helix B of erythropoietin. The certificate and the vial label carry Ara-290, which is the name the batch is released under.

What are Ara-290’s sequence, formula and molecular weight?

pGlu-Glu-Gln-Leu-Glu-Arg-Ala-Leu-Asn-Ser-Ser, or pGlu-EQLERALNSS in one-letter code: eleven residues from helix B of erythropoietin, with a pyroglutamate at the N-terminus and a free acid at the C-terminus. C51H84N16O21, molecular weight (average mass) 1,257.3.

How much does Ara-290 cost?

It is sold only by special order, 50 boxes per strength, from $80.87 a sealed box of 10 vials, up to $115.31 for the largest strength, which works out at $0.721 per mg at its best-priced size. The smallest order is 50 boxes of RA10, $4,043.50 of goods, with freight included to a US address. Every strength and its price per vial is in this page’s price table.

Which Ara-290 size is cheapest per mg?

RA16, 16mg x 10 vials, at $0.721 per mg, which is 11 percent less per mg than RA10, at $0.809 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 Ara-290?

No, and not a single box either. Ara-290 is a special-order line, brought in on a 50-box minimum rather than held in stock, so the smallest order is 50 sealed boxes of one strength: for RA10, 10mg x 10 vials, that is 50 boxes at $80.87, $4,043.50 of goods. 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 Ara-290 strengths are in stock today?

None today. RA10 and RA16 are special order: brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.

How is Ara-290 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 Ara-290?

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. Ara-290 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 Ara-290?

Yes. For Ara-290 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.
