PLGF Protein, Human (HEK293, mFc)

The PLGF-2 protein is a key growth factor for angiogenesis and endothelial cell growth, crucially stimulating cell proliferation and migration by binding to the FLT1/VEGFR-1 receptor. It coordinates the angiogenic process, regulates blood vessel growth, and exhibits additional binding capabilities to NRP1/neuropilin-1 and NRP2/neuropilin-2. PLGF Protein, Human (HEK293, mFc) is the recombinant human-derived PLGF protein, expressed by HEK293 , with C-mFc labeled tag. The total length of PLGF Protein, Human (HEK293, mFc) is 170 a.a., with molecular weight of ~43.7 kDa.

The PLGF-2 Protein, a growth factor with significant activity in angiogenesis and endothelial cell growth, plays a crucial role in stimulating the proliferation and migration of these cells. Through binding to the FLT1/VEGFR-1 receptor, PLGF-2 orchestrates angiogenic processes and contributes to the regulation of vascular growth. Notably, the isoform PlGF-2 exhibits additional binding capabilities, forming interactions with NRP1/neuropilin-1 and NRP2/neuropilin-2 in a heparin-dependent manner. Beyond its angiogenic functions, PLGF-2 also promotes tumor growth, implicating its involvement in pathological angiogenesis associated with cancer. Structurally, PLGF-2 exists as an antiparallel homodimer linked by disulfide bonds, and it can further manifest as a heterodimer with VEGFA/VEGF. The presence of isoform PlGF-3 as both a homodimer and monomer adds to the complexity of PLGF proteins, highlighting their diverse roles in modulating vascular processes and tumorigenesis.

Immobilized human PGF-mFc at 10 μg/mL (100 μL/well) can bind human VEGFR1-His . The EC₅₀ of human VEGFR1-His is 0.19-0.43 μg/mL.

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.
