Description : | Insulin-like Growth Factor-Binding Protein 3 (IGF-BP3) belongs to the IGFBP family, which are all cysteinerich proteins with conserved cysteine and have an IGFBP domain and a thyroglobulin type-I domain. Mature human IGF-BP3 contains 264 a.a. with three potential N-linked and two potential O-linked glycosylation sites. It is expressed by most tissues and has higher levels during extrauterine life and peak during puberty. The expression of IGF-BP3 in fibroblasts is stimulated by mitogenic growth factors such as Bombesin, Vasopressin, PDGF, and EGF. The protein forms a ternary complex with IGF-I or II and acid-labile subunit. In this form, it circulates in the plasma, prolonging the half-life of IGFs and altering their interaction with cell surface receptors. Decreased plasma levels of IGF-BP3 often happen during the progression of prostate cancer from benign to metastatic disease. |

Endotoxin : | Less than 1 EU/μg of rHuIGF-BP3 as determined by LAL method. |
Purity : | >98% by SDS-PAGE and HPLC analysis. |
Storage : | Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70 centigrade as supplied. 1 month, 2 to 8 centigrade under sterile conditions after reconstitution. 3 months, -20 to -70 centigrade under sterile conditions after reconstitution. |
Reconstitution : | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤-20 centigrade. Further dilutions should be made in appropriate buffered solutions. |

Q&As (5)
Ask a questionYes, genetic variations can affect IGFBP3 expression, potentially leading to differences in protein levels among individuals.
IGFBP3 is involved in bone metabolism and is associated with bone mineral density. Low levels of IGFBP3 have been linked to decreased bone density and increased risk of fractures.
The potential side effects of therapies targeting IGFBP3 are still being studied, and it varies depending on the specific treatment approach being used.
Healthy lifestyle choices, including a balanced diet and regular exercise, can positively influence IGFBP3 levels, promoting overall health and reducing the risk of related diseases.
IGFBP3 deficiency can impact children's growth and development, potentially leading to short stature and delayed puberty, as IGFBP3 is a key regulator of growth hormone actions.
