IGF-1 LR3 1 mg Research Peptide (USA Domestic)

IGF-1 LR3 1 mg, a lyophilized research peptide for in vitro use, which is supplied as a multi-vial unit and shipped from a United States domestic facility. Total powder content in one unit, sealed in vials (not one container). 

The material is a reagent used in the laboratory, suitable for qualified research staff. It is not for use in humans or animals, and does come with no instructions on how to prepare or dose.

IGF-1 LR3 Product Overview

The IGF-1 lr3 peptide is a recombinant human IGF-1 peptide, in which two amino acids have been changed intentionally. It has a 13-residue extension at its N terminus, and Arginine is substituted for by glutamic acid at residue 3. 

In the end, the result is an 83-amino-acid chain, which is nearly 9.1 kDa, compared to 70 amino acids and around 7.6 kDa of the native protein. Supplied as a white lyophilizate in a sealed glass. These purity numbers represent a great deal more than the compound and are determined by SDS-PAGE or HPLC of a single batch.

What Is Included in the 1 mg Package?

An IGF-1 LR3 1 mg unit is not one large vial. The IGF 1 LR3 1mg format carries a ZPHC brand marking and divides the total across five sealed containers, so a laboratory opens one and leaves the rest sealed and dated.

• Five glass vials, IGF-1 LR3 0.2 mg of lyophilized powder in each
• Lot code on the vial label and on the outer carton
• Manufacturer’s scratch validation panel on the packaging
• No bacteriostatic water, diluent, syringes, or filters
• No insert carrying preparation or handling protocols

Pack formats change between production runs, so the live product card stays the reference for what the current ZPHC IGF-1 LR3 unit holds.

Compound Identity and Laboratory Research Context

Three of the same type of molecules become confused in catalogues. The unmodified 70-residue protein, native recombinant human IGF-1, is indexed in the FDA substance registry as “mecasermin” (UNII: 7GR9I2683O; CAS: 68562-41-4). The truncated IGF-1 is called DES(1-3) IGF-1, which consists of 67 residues and has a mass of approximately 7.37 kDa. The other way around, the CAS number is 143045-27-6, and the official synonym is Long R3 IGF-1.

The reason why the analogue is seen in cell culture and preclinical protocols where steady free IGF-1 concentration is required is that both the position-3 substitution and the lower affinity for the IGF binding proteins that bind IGF-1 in circulation cause this. The results are still in the preliminary phase.    

Quality, Authenticity, and Batch Documentation

The present ZPHC packaging will feature the silver scratch panel. The lifting of the coating reveals a single-use validation code: a combination of letters, numbers, and symbols for recent stock, or a serial number consisting of four blocks of characters, such as 5XTC-S35E-N2TA-68HN, for older runs. The code is entered into the manufacturer’s validation form – if there is no code or it is filled with “used,” it is a reason for questioning the supplier.

The lot indicated on the vial should match the lot on the carton, and with any Certificate of Analysis provided. Analytical values are specific to the batch of the product as it is in the hands of the purchaser; a COA should be requested for that particular batch.

Storage and Laboratory Handling

Sealed vials are stored dry, frozen (under -18 °C for longer than short-term holding) and not subjected to repeated freeze-thaw cycles. A warm parcel isn’t a ruined parcel, as lyophilized powder will survive short-term room temperature transit. Vials are stored in the dark and away from humidity and heat. Handling is the responsibility of trained staff in a qualified laboratory, using sterile technique, and the vial is recorded in the reagent inventory.

Ordering and USA Domestic Shipping

The live product card will reflect the current price available, stock, and the lot currently shipping. You should read the IGF1 LR3 card when you are going to buy IGF 1 LR3, not the cached version. Units offered as IGF-1 LR3 for sale here are packaged in a rigid package that blocks the light and comes from a domestic United States facility. Carrier, tracking, and transit windows are confirmed upon checkout.

Important Research-Use-Only Notices

This IGF1 LR3 research peptide is provided for laboratory research only to and by qualified research personnel under controlled conditions. It is not a drug, food, food additive, dietary supplement, cosmetic, or household chemical, and has not been approved for any of these uses. Not for human or veterinary use, whatsoever or in any amount, by any route.

It is not intended to diagnose, treat, cure, or prevent any disease or condition in humans or animals. The information provided in this description is not intended to be medical advice, an experimental protocol, or a recommendation to place the material into a living subject.

Under the rules of the buyer’s jurisdiction and institution, the buyer assumes complete responsibility for the lawful handling, storage, record-keeping, and disposal. Resale, re-packaging, or transferring for any other laboratory purpose is not allowed. Orders are accepted subject to the same conditions as the purchaser is a research professional.
