Reconstitution	Briefly centrifuged the vial prior to opening to bring the contents to the bottom. Reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL. It is recommended to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. The default final concentration of glycerol is 50%.
Storage	1. Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. 2. Avoid repeated freeze-thaw cycles. 3. Store working aliquots at 4°C for up to one week. 4. In general, protein in liquid form is stable for up to 6 months at -20°C/-80°C. Protein in lyophilized powder form is stable for up to 12 months at -20°C/-80°C.
Notes	Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Details

Target Function	IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors. Promotes cell migration.
Subcellular Location	Secreted.
Database References	KEGG: mmu:16006 STRING: 10090.ENSMUSP00000020704 UniGene: Mm.21300

the hepatokine IGFBP1 is a critical liver-bone hormonal relay that promotes osteoclastogenesis and bone resorption as well as an essential mediator of FGF21-induced bone loss PMID: 26456333
Data suggest expression of Igfbp1 in liver is regulated by dietary factors; carnosine supplementation down-regulates expression of Igfbp1 in liver of obese/diabetic mice; mechanism involves suppression of Hif1a (hypoxia inducible factor 1 alpha). PMID: 25869614
serum IGFBPI protein could provide an easily measured biomarker for early detection of alcohol-induced liver injury in humans PMID: 24152801
These results show that RTEF-1-stimulated IGFBP-1 expression may be central to the mechanism by which RTEF-1 attenuates blood glucose levels. PMID: 22843786
Global deletion of Igfbp1 in a c-Myc transgenic model did not accelerate the development of prostate cancer. Global Igfbp1 deletion did result in a significant increase in body weight and body fat mass. PMID: 21903863
IGFBP-1 functions as a critical hepatic survival factor in the liver by reducing the level of proapoptotic signals PMID: 12511596
IGFBP-1 may support liver regeneration at least in part via its effect on MAPK/ERK and C/EBP beta activities. These findings are the first demonstration of the involvement of IGFBP-1 in the regulation of in vivo mitogenic signaling pathways. PMID: 12556485
Induction of IFGBP1 expression by amino acid deprivation of HepG2 hepatoma cells involves both a transcriptional activation and an mRNA stabilization due to its 3'UTR. PMID: 15862298

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
