IGF-1 LR3 1mg

Description

IGF-1 LR3 1mg is a 1mg vial of IGF-1 LR3, an IGF-1 analog, supplied by Blue Sky Peptide as freeze-dried powder. This batch tested at 97.57% purity. It’s intended for lab research only.

About IGF-1 LR3

IGF-1 LR3 is an 83-amino-acid analog of IGF-1 with an arginine swap at position 3 and a 13-amino-acid extension. Those changes stop it binding IGF binding proteins, so it stays active much longer.

It’s widely used in cell culture media.

How IGF-1 LR3 acts in the lab

IGF-1 is the hormone that carries out much of growth hormone’s effect on cells. Most of it in the body is bound by IGF binding proteins, which hold it inactive.

LR3 has an arginine in place of glutamate at position 3 plus a 13-residue extension. Binding proteins barely recognize it, so it stays free and active far longer. That’s why it’s the standard IGF-1 in cell culture media.

Published IGF-1 LR3 studies

It was developed for cell culture in the 1990s.

In cell culture it’s several times more potent than IGF-1.

How IGF-1 LR3 compares

IGF-1 LR3 1mg is easier to place once you see it next to the compounds it’s usually compared with. IGF-1 LR3 is an 83-amino-acid IGF-1 analog that avoids binding proteins and lasts for hours. The others:

• IGF-1 DES is IGF-1 missing three residues, potent locally but cleared faster than IGF-1 LR3
• MGF is the E-domain peptide from the muscle-specific IGF-1 splice variant
• PEG-MGF is MGF with a PEG chain added so it lasts much longer

These sit downstream of growth hormone, on the IGF-1 side of the axis. They differ in how they avoid binding proteins, how long they last and which receptor they rely on. See them all on our growth hormone peptides page.

IGF-1 LR3 1mg reconstitution and concentration

Here’s the math for 1mg of peptide:

• 1mL of water gives 1mg/mL
• 2mL of water gives 0.5mg/mL

Go with whichever number is easiest to work with in your protocol, and label the vial with the concentration and the date you mixed it.

Most labs use sterile bacteriostatic water. Let the vial reach room temperature, run the water slowly down the inside of the glass, then roll the vial gently until the powder dissolves. Don’t shake it. Shaking can shear peptide chains.

Storing IGF-1 LR3 1mg

The dry powder keeps best cold. A freezer at -20°C is ideal for long-term storage, and a fridge works for a few weeks. After reconstitution, store it in the fridge and finish it within roughly four weeks.

If you keep several vials going at once, our vial storage case holds ten upright with room for labels, and the hard storage box protects them in a shared freezer or in transit.

IGF-1 LR3 1mg quality and batch records

Purity for this batch of IGF-1 LR3 1mg came back at 97.57% by HPLC and mass spectrometry. That’s the figure for the batch currently in stock.

Note the batch number on the label when the vial arrives. That’s what the certificate of analysis is filed under, and we’ll send you a copy on request.

Keep the batch number with your records. It’s the quickest way to match a vial to its paperwork later.
