Scientific Data Images for Recombinant Human GDNF Protein
Recombinant Human GDNF Protein SEC-MALS.
Recombinant human GDNF (Catalog # 212-GD) has a molecular weight (MW) of 27.5 kDa as analyzed by SEC-MALS, suggesting that this protein is a homodimer. MW may differ from predicted MW due to post-translational modifications (PTMs) present (i.e. Glycosylation).
Recombinant Human GDNF Protein Bioactivity
Recombinant Human GDNF (Catalog # 212-GD) induces SH-SY5Y human neuroblastoma cell proliferation in the presence of Recombinant Human GFRa-1 Fc Chimera (Catalog # 714-GR). The activity is approximately 9-fold greater than the top competitor's GDNF.
Recombinant Human GDNF Protein SDS-PAGE
1 μg/lane of Recombinant Human GDNF was resolved with SDS-PAGE under reducing (R) and non-reducing (NR) conditions and visualized by silver staining, showing single bands at 17 kDa and 34 kDa, respectively.Formulation, Preparation and Storage
Carrier Free
What does CF mean?CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.
What formulation is right for me?In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: GDNF
Native GDNF, a disulfide-linked homodimeric glycoprotein, is a novel member of the TGF-beta superfamily. Human GDNF cDNA encodes a 211 amino acid residue prepropeptide that is processed to yield a dimeric protein. Mature human GDNF was predicted to contain two 134 amino acid residue subunits. NS0 expressed mature human GDNF lacks 31 residues from the amino-terminus of the predicted sequence. This glycosylated recombinant mature human GDNF still contains the seven conserved Cys residues found in all members of the TGF-beta superfamily and is biologically active. The GDNF sequence contains two potential glycosylation sites and insect cell‑expressed recombinant rat GDNF proteins are glycosylated. Mature rat and human GDNF exhibit approximately 93% amino acid sequence identity and show considerable species cross-reactivity. Cells known to express GDNF include Sertoli cells, type 1 astrocytes, Schwann cells, neurons, pinealocytes and skeletal muscle cells.
