簡單介紹：

重組人頭蛋白與其它公司提供的重組蛋白不同，rHuNoggin蛋白產品為采用CFS的無細胞麥胚蛋白合成系統表達出來的重組蛋白，可表達出對細胞有毒性、易被蛋白酶降解的蛋白；并獲得具有良好的可溶性，并有翻譯后修飾、從而部分具有功能的蛋白.同時獨有的全自動蛋白純化技術則簡便高效，將蛋白純化過程中對蛋白的損傷降低到*小程度.重組人頭蛋白（全長序列）產品可用于Western Blot驗證、抗體制備、蛋白檢測、ELISA等試驗中.

重組人頭蛋白

Species Human

Accession Q13253

GeneID 9241

Source Escherichia coli.

Molecular Weight 重組人頭蛋白Approximately 46.3 kDa, non-disulfide-linked homodimer consisting of two 206 amino acid polypeptide chains.

Quantity 5μg/20μg/1000μg

AA Sequence MQHYLHIRPA PSDNLPLVDL IEHPDPIFDP KEKDLNETLL RSLLGGHYDP GFMATSPPED RPGGGGGAAG GAEDLAELDQ LLRQRPSGAM PSEIKGLEFS EGLAQGKKQR LSKKLRRKLQ MWLWSQTFCP VLYAWNDLGS RFWPRYVKVG SCFSKRSCSV PEGMVCKPSK SVHLTVLRWR CQRRGGQRCG WIPIQYPIIS ECKCSC

Purity > 95 % by SDS-PAGE and HPLC analyses.

Biological Activity 重組人頭蛋白Fully biologically active when compared to standard. The ED₅₀ as determined by inhibiting BMP-4-induced alkaline phosphatase production of murine ATDC5 cells is less than 3.0 ng/ml, corresponding to a specific activity of > 3.3 × 10⁵ IU/mg in the presence of 5 ng/ml rHuBMP-4.

Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation Lyophilized from a 0.2 μm filtered concentrated solution in 30 % acetonitrile, 0.1 % TFA.

Endotoxin Less than 1 EU/μg of rHuNoggin as determined by LAL method.

Reconstitution 重組人頭蛋白We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in 10mM HAc to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.

Storage This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C. Avoid repeated freeze/thaw cycles.

Background Noggin encoded by the NOG gene, was first isolated from Xenopus, having the function of inducing secondary axis formation in frog embryos. It inhibits TGF-β family ligands and preventing them from binding to their corresponding receptors. Noggin was originally found as a BMP-4 antagonist, and then has been shown to modulate the activities of other BMPs (BMP-2, 7, 13 and 14). Additionally, it has pleiotropic effect, both in early development and later stages. The results of the mouse knockout of noggin suggest that it is involved in numerous developmental processes, such as neural tube fusion and joint formation. In recent report, proximal symphalangism (SYM1) and multiple synostoses syndrome (SYNS1) have relation with the mutant of evolutionarily conserved amino acid residues of Noggin. Mature human Noggin shares 99 %, 99 %, 98 %, 97 % and 89 % a.a. sequence identity with mouse, rat, bovine, equine and chicken Noggin, respectively.
