  • 纯度
    > 95 % SDS-PAGE.

  • 形式
    Lyophilised
  • Concentration information loading...

制备和贮存

  • 稳定性和存储

    Shipped at 4°C. After reconstitution store at -20ºC. Avoid freeze / thaw cycles.

    Preservative: None
    Constituents: 10% Trehalose, 1% Human serum albumin

  • 复溶
    It is recommended that 0.5 ml of sterile phosphate-buffered saline be added to the vial. Following reconstitution short-term storage at 4°C is recommended, with longer-term storage in aliquots at -18 to -20°C. Repeated freeze thawing is not recommended.

  • 功能
    Growth factor active in angiogenesis and endothelial cell growth, stimulating their proliferation and migration. It binds to the receptor FLT1/VEGFR-1. Isoform PlGF-2 binds NRP1/neuropilin-1 and NRP2/neuropilin-2 in a heparin-dependent manner.
  • 组织特异性
    While the three isoforms are present in most placental tissues, PlGF-2 is specific to early (8 week) placenta and only PlGF-1 is found in the colon and mammary carcinomas.
  • 序列相似性
    Belongs to the PDGF/VEGF growth factor family.
  • 结构域
    Isoform PlGF-2 contains a basic insert which acts as a cell retention signal.
  • 翻译后修饰
    N-glycosylated.
  • 细胞定位
    Secreted. The three isoforms are secreted but PlGF-2 appears to remain cell attached unless released by heparin.
  • Information by UniProt

  • Densitometry of protein isoforms visualised by 2-DE.
    The densitometry scan demonstrates the purified human cell expressed protein exists in multiple isoforms, which differ according to their level of post-translational modification.
    The triangle indicates the theoretical MW and pI of the protein.
  • 1D SDS-PAGE of ab84148 before and after treatment with glycosidases to remove oligosaccharides.
    Lane 1: ab84148
    Lane 2: ab84148 treated with PNGase F to remove potential N-linked glycans
    Lane 3: ab84148 treated with a glycosidase cocktail to remove potential N- and O-linked glycans.
    10µg protein loaded per lane; Deep Purple™ stained.

    Drop in MW after treatment with PNGase F indicates presence of N-linked glycans. A further drop in MW after treatment with the glycosidase cocktail indicates the presence of O-linked glycans. Additional bands in lane 2 and lane 3 are glycosidase enzymes.
