產品詳情
簡單介紹：
重組人類B細胞成熟抗原/ TNFRSF17蛋白與其它公司提供的重組蛋白不同，rHuBCMA/TNFRSF17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.重組人類B細胞成熟抗原/ TNFRSF17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.
詳情介紹：
重組人類B細胞成熟抗原/ TNFRSF17蛋白
| Synonyms | TNFRSF17, BCM, CD269 |
| Species | Human |
| Accession | Q02223 |
| GeneID | 608 |
| Source | Escherichia coli. |
| Molecular Weight | 重組人類B細胞成熟抗原/ TNFRSF17蛋白Approximately 5.4 kDa, a single non-glycosylated polypeptide chain containing 50 amino acids. |
| Quantity | 5μg/20μg/1000μg |
| AA Sequence | AGQCSQNEYF DSLLHACIPC QLRCSSNTPP LTCQRYCNAS VTNSVKGTNA |
| Purity | > 98 % by SDS-PAGE and HPLC analyses. |
| Biological Activity | 重組人類B細胞成熟抗原/ TNFRSF17蛋白Fully biologically active when compared to standard. The ED50 as determined by its ability to inhibit APRIL-mediated proliferation of anti-IgM stimulated murine B cells is no less than 40 ng/ml, corresponding to a specific activity of > 2.5 × 104 IU/mg in the presence of 100 ng/ml human APRIL. |
| 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 | 重組人類B細胞成熟抗原/ TNFRSF17蛋白Less than 1 EU/μg of rHuBCMA as determined by LAL method. |
| Reconstitution | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA 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 | B-Cell Maturation Antigen (BCMA), encoded by the TNFRSF17 gene in humans. It is a member of the TNF receptor superfamily and a type III membrane protein containing one extracellular cysteine rich domain. It is expressed on mature B-cells and other B-cell lines. BCMA can binds to TNFSF13B/BLyS/BAFF and TNFSF13/APRIL, and has functions that promotes B-cell survival, plays a role in the regulation of humoral immunity, and activates NF-kappa-B and JNK BCMA. |
