Serpin F1 Protein, Mouse (HEK293, His)

Serpin F1 is a neurotrophin that significantly induces extensive neuronal differentiation of retinoblastoma cells and exhibits potent anti-angiogenic effects. Its unique conformation lacks the S (stress) to R (relaxation) transition typical of active serpins, resulting in a lack of serpin activity. Serpin F1 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Serpin F1 protein, expressed by HEK293 , with C-His labeled tag. The total length of Serpin F1 Protein, Mouse (HEK293, His) is 398 a.a., with molecular weight of 60-65 kDa.

Serpin F1, a neurotrophic protein, emerges as a key inducer of extensive neuronal differentiation in retinoblastoma cells. Notably, it exerts a potent inhibitory effect on angiogenesis. Distinguished by its unique conformational characteristics, Serpin F1 does not undergo the S (stressed) to R (relaxed) transition typical of active serpins, resulting in the absence of serine protease inhibitory activity. Furthermore, its interaction with PNPLA2 serves to stimulate the phospholipase A2 activity of PNPLA2, underscoring the multifaceted roles of Serpin F1 in cellular processes.

Measured by its binding ability in a functional ELISA. Immobilized mouse SERPINF1-His at 10 μg/mL (100 μL/well) can bind human GST-CSNK2A1 with a linear range of 0.31-2.5 μg/mL.

60-65 kDa

Greater than 95% as determined by reducing SDS-PAGE

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. 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.
