Mouse Beta Klotho Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Mouse Beta Klotho Protein is expressed from HEK293 with His tag at the C-Terminus
It contains Phe53-Pro994 [Accession | Q99N32-1].

分子量大小(Molecular Weight)

The protein has a predicted MW of 109.91 kDa. Due to glycosylation, the protein migrates to 120-130 kDa based on Bis-Tris PAGE result.

纯度(Purity)

>90% as determined by Bis-Tris PAGE; >90% as determined by HPLC

内毒素(Endotoxin)

Less than 1 EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Bis-Tris PAGE

Mouse Beta Klotho on Bis-Tris PAGE under reduced condition. The purity is greater than 90%.

SEC-HPLC

The purity of Mouse Beta Klotho Protein is greater than 90% as determined by SEC-HPLC.

SPR Data

Human FGFR4, hFc Tag captured on CM5 Chip via Protein A can bind Mouse Beta Klotho, His Tag with an affinity constant of 36.97 nM as determined in SPR assay (Biacore T200).

背景(Background)

Beta-klotho (KLB) is a coreceptor required for endocrine fibroblast growth factor (FGF) 15/19 and FGF21 signaling in the brain. Klb is prominent within the hypothalamus, which is consistent with its metabolic functions, but diverse roles for Klb are now emerging. Central Klb expression is low but discrete and may govern FGF-targeted sites.

分子别名(Synonyms)

betaKlotho; beta-klotho; BKL; KLB; klotho beta like; Klotho beta; MGC142213;βKlotho; β-klotho; klotho β like; Klotho β

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
