FABP4 Protein, Human (His)
Based on 1 Customer Validation
FABP4 Protein, expressed mainly in adipocytes, crucially mediates lipid and retinoic acid transport. It binds long-chain fatty acids and retinoic acid, facilitating delivery to nuclear receptors. Functioning as a monomer and forming homodimers, FABP4 interacts with PPARG, contributing to its involvement in fatty acid metabolism and signaling pathways. FABP4 Protein, Human (His) is the recombinant human-derived FABP4 protein, expressed by E. coli , with N-6*His labeled tag.
- Species: Human
- Source: E. coli
-
Storage:Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Description
FABP4 Protein, expressed mainly in adipocytes, crucially mediates lipid and retinoic acid transport. It binds long-chain fatty acids and retinoic acid, facilitating delivery to nuclear receptors. Functioning as a monomer and forming homodimers, FABP4 interacts with PPARG, contributing to its involvement in fatty acid metabolism and signaling pathways. FABP4 Protein, Human (His) is the recombinant human-derived FABP4 protein, expressed by E. coli , with N-6*His labeled tag.
Background
FABP4, a lipid transport protein predominantly expressed in adipocytes, serves as a crucial mediator in lipid and retinoic acid transport. Its role involves binding to both long-chain fatty acids and retinoic acid, facilitating their delivery to respective receptors within the nucleus. FABP4 functions as a monomer and can form homodimers. Additionally, it engages in interactions with PPARG, contributing to its involvement in key processes related to fatty acid metabolism and signaling pathways.
Verified Bioactivity
Measured in a cell proliferation assay using MCF-7 cells. The ED50 for this effect is 65.15 ng/mL, corresponding to a specific activity is 1.535×10^4 units/mg.

Product Properties
Lyophilized powder
1.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
2.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4, 8% trehalose.
Please refer to the lot-specific COA for specific buffer information.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
