Recombinant Human Noggin GMP Protein, CF Summary
Manufactured and tested under current Good Manufacturing Practice (GMP) guidelines.
Predicted N-terminal sequence: Gln-His-Tyr-Leu-His-Ile-Arg-Pro-Ala-Pro
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.
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.

GMP-grade Recombinant Human Noggin (Catalog # 6057-GMP) inhibits BMP-4-induced alkaline phosphatase production in the ATDC5 mouse chondrogenic cell line. The ED50for this effect is 0.04-0.2 µg/mL in the presence of 50 ng/mL of Recombinant Human BMP-4 (Catalog # 314-BP).
1 μg/lane of GMP-grade Recombinant Human Noggin (Catalog # 6057-GMP) was resolved with SDS-PAGE under reducing (R) and non-reducing (NR) conditions and visualized by silver staining, showing bands at 31 kDa and 57 kDa, respectively.
Noggin is a secreted homodimeric glycoprotein that is an antagonist of bone morphogenetic proteins (BMPs) (1, 2). Human Noggin cDNA encodes a 232 amino acid (aa) precursor protein; cleavage of a 19 aa signal peptide generates the 213 aa mature protein which contains an N-terminal acidic region, a central basic heparin‑binding segment and a C-terminal cysteine-knot structure (2). Secreted Noggin probably remains close to the cell surface due to its binding of heparin‑containing proteoglycans (3). Noggin is very highly conserved among vertebrates, such that mature human Noggin shares 99%, 99%, 98%, 97% and 89% aa sequence identity with mouse, rat, bovine, equine and chicken Noggin, respectively. Noggin binds some BMPs such as BMP-4 with high affinity and others such as BMP-7 with lower affinity. It antagonizes BMP bioactivities by blocking epitopes on BMPs that are needed for binding to both type I and type II receptors (2, 4). During embryogenesis, Noggin antagonizes specific BMPs at defined times, for example, during neural tube, somite and cardiomyocyte growth and patterning (5-7). During skeletal development, Noggin prevents chondrocyte hyperplasia, thus allowing proper formation of joints (4). Mutations within the cysteine-knot region of human Noggin are linked to multiple types of skeletal dysplasias that result in apical joint fusions (8). Noggin is expressed in defined areas of the adult central nervous system and peripheral tissues such as lung, skeletal muscle and skin (1). During culture of human embryonic stem cells (hESC) or neural stem cells under certain conditions, addition of Noggin to antagonize BMP activity may allow stem cells to proliferate while maintaining their undifferentiated state, or alternatively, to differentiate into dopaminergic neurons (6, 9 - 13). Noggin also appears to maintain adult stem cell populations in-vivo, for example, maintaining neural stem cells within the hippocampus (13).

The vial is supposed to contain lyophilized protein but it appears to be empty. Is there anything in it?
Pellets can be dislodged during shipping and become disbursed on the vial wall and in the cap. Centrifuge or tap the vial on the benchtop to return this material to the vial bottom. If this does not reveal a pellet, closely inspect the cone of the vial. Some pellets appear as only a tiny amount of material or as a transparent film due to the original buffer formulation. This is a normal appearance for many proteins. For example, if the product is originally lyophilized from a solvent such as acetonitrile or ethanol, and supplied carrier-free, you may not be able to detect the pellet with the naked eye. This does not mean the vial is empty. Reconstitute the vial as directed. After reconstitution, protein concentration can be tested with a spectrophotometer.
What is the recommended method for reconstitution of a lyophilized protein or antibody?
Unless more specific directions are on the Certificate of Analysis provided with the product, we suggest the following procedure to ensure optimal recovery: 1. Allow the vial and reconstitution buffer to equilibrate to room temperature. 2. Briefly centrifuge the vial to ensure that all lyophiliate is collected at the bottom of the vial. 3. Add the amount of buffer required to achieve the concentration recommended on the product insert. 4. Allow the vial to reconstitute for 15-30 minutes at room temperature with gentle agitation, like on a rocker platform or rotating by hand. Avoid vigorous shaking that can cause foaming and protein denaturation. 5. Aliquot into volumes greater than 20 μL and store as indicated on the product insert. If the vial exhibits flakes or particulates, mix the product for a couple of hours at room temperature and then at 4oC overnight. Contact Technical Service if product does not go into solution.
