More Info

Introduction
Borrelia belongs to a genus of bacteria of the spirochete phylum. Borrelia causes borreliosis, which is a zoonotic, vector-borne disease transmitted mainly by ticks and some by lice, depending on the species. Of the 36 known species of Borrelia, 12 are distinguished to cause Lyme disease or borreliosis and are transmitted by ticks. The main Borrelia species causing Lyme disease are Borrelia burgdorferi, Borrelia afzelii, and Borrelia garinii. The Borrelia genus members have a linear chromosome which is about 900 kbp in length as well as an excess of both linear and circular plasmids in the 5-220 kbp size range. The plasmids are atypical, as compared to most bacterial plasmids, since they contain many paralogous sequences, a large number of pseudogenes and, in some cases, essential genes. Moreover, a number of the plasmids have features suggesting that they are prophages.
Physical Appearance

More Info

Introduction
NQO1 belongs to the NAD(P)H dehydrogenase (quinone) family and encodes a cytoplasmic 2-electron reductase. NQO1 acts as an imperative part of cellular antioxidant defense by detoxifying quinines therefore preventing the formation of reactive oxygen species. It seems that NQO1 serves as a quinone reductase relating to conjugation reactions of hydroquinons involved in detoxification pathways in addition to biosynthetic processes such as the vitamin K-dependent gamma-carboxylation of glutamate residues in prothrombin synthesis. Altered NQO1 expression is seen in many tumors and also linked to Alzheimer’s disease. NQO1 gene mutations are linked to tardive dyskinesia which is an increased risk of hematotoxicity after exposure to benzene, and susceptibility to various forms of cancer.

More Info

Introduction
Ipamorelin is a peptide selective agonist of the ghrelin/growth hormone secretagogue receptor and a growth hormone secretagogue. Ipamorelin is a pentapeptide that was derived from GHRP1. Ipamorelin significantly increases plasma growth hormone levels in both animals and humans. Like pralmorelin and GHRP-6, ipamorelin does not affect prolactin, FSH, LH or TSH levels. However, unlike GHRP2 and GHRP6, but as growth hormone-releasing hormone (GHRH), ipamorelin does not stimulate the secretion of adrenocorticotropic hormone (ACTH) or cortisol, and is highly selective for inducing the secretion only of GH.
Synonyms
Ipamorelin
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Stability
Lyophilized Ipamorelin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Ipamorelin should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Solubility
It is recommended to reconstitute the lyophilized Ipamorelin in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Amino Acid Sequence
Aib-His-D-2-Nal-D-Phe-Lys-NH2.

Background
1. What are gel ice packs used for?
Gel ice packs are used to keep temperature-sensitive products cold during transportation. They are widely used for shipping recombinant proteins, antibodies, enzymes, reagents, biological samples, diagnostic kits, pharmaceuticals, vaccines, and other laboratory materials that require refrigerated conditions.
ProSpec gel ice packs provide a reliable cooling source when used together with insulated shipping boxes, helping maintain the cold chain throughout transit.

2. What are the best gel ice packs for shipping laboratory samples?
The best gel ice packs provide long-lasting cooling, are reusable, leak-resistant, and maintain a stable temperature throughout transportation.
For 30 years, ProSpec has used its own gel ice packs to ship laboratory products worldwide. Designed specifically for research and biotechnology applications, they help protect valuable temperature-sensitive products during domestic and international shipping.

3. How do I keep biological samples cold during shipping?
To maintain sample integrity, biological materials should be shipped inside a high-performance insulated shipping box together with properly frozen gel ice packs.
For maximum thermal protection, ProSpec recommends combining its reusable gel ice packs with insulated shipping boxes constructed using Vacuum Insulated Panel (VIP) technology, which significantly reduces heat transfer and extends cooling performance.

4. How long do gel ice packs stay cold?
Cooling duration depends on several factors, including:
• Number of gel ice packs
• Type of insulated packaging
• Ambient temperature
• Shipment weight
• Transit time
Using ProSpec VIP insulated packaging together with ProSpec gel ice packs can significantly extend cooling duration compared to conventional insulated packaging.

5. Are ProSpec gel ice packs reusable?
Yes.
ProSpec gel ice packs are designed for repeated use. After delivery, simply refreeze them before the next shipment.
Reusable cooling packs reduce packaging costs, minimize waste, and provide an environmentally friendly solution for cold chain shipping.

6. What are the advantages of gel ice packs compared to regular ice?
Gel ice packs offer several important advantages over conventional ice:
• Leak-resistant
• Less risk of water damage
• Reusable
• Easy to freeze and store
• Longer-lasting cooling
• More uniform temperature distribution
• Antibacterial material
• Cleaner handling during shipping
Unlike pre-filled packs, ProSpec gel ice packs are supplied as a powder. Simply add water, seal the pack, freeze it, and it is ready for use.

7. What products should be shipped with gel ice packs?
Gel ice packs are recommended for shipping:
• Recombinant proteins
• Cytokines
• Growth factors
• Antibodies
• Enzymes
• ELISA kits
• Cell culture reagents
• Diagnostic kits
