Recombinant Human FABP2/I-FABP

Recombinant Human FABP2/I-FABP  (C134)

 

产品说明(Description)

Recombinant Human Fatty Acid-Binding Protein 2 is produced by our E.coli expression system and the target gene encoding Met1-Asp132 is expressed with a 6His tag at the N-terminus, 6His tag at the C-terminus. 

Accession #: P12104

Known as: Fatty Acid-Binding Protein Intestinal; Fatty Acid-Binding Protein 2; Intestinal-Type Fatty Acid-Binding Protein; I-FABP; FABP2; FABPI

 

制剂（Formulation）

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

 

质量控制（Quality Control） 

 

Purity:            Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin:    Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

 

复溶（Reconstitution）

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.    

 

保存（Storage）

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months.     

 

背景（Background）

Fatty Acid-Binding Protein 2 (FABP2) is a cytoplasm protein that belongs to the Fatty-acid binding protein (FABP) family of calycin superfamily. Fatty acid binding proteins are a family of small, highly conserved, cytoplasmic proteins that bind long-chain fatty acids. FABP2 is expressed in the small intestine and at much lower levels in the large intestine, the highest expression levels in the jejunum. FABP2 binds saturated long-chain fatty acids with a high affinity, but binds with a lower affinity to unsaturated long-chain fatty acids. FABP2 is probably involved in triglyceride-rich lipoprotein synthesis and may also help maintain energy homeostasis by functioning as a lipid sensor.
