| 商品货号： | TS147125 |
| Designations： | pBend4 plasmid in E. coli |
| Depositors： | C Zwieb |
| Biosafety Level： | 1 |
| Vector Information： | Size (kb): 3.201 Vector: pBend4 (plasmid) Promoters: Promoter T7 (phi10) Construction: pBluescriptSK- Marker(s):ampR Construct size (kb): 3.20199990272522 Features: marker(s): ampR promoter: T3 promoter: T7 (phi10) replicon: pMB1 MCS: HindIII...EcoRI |
| Applications： | vector containing primer sites useful for sequencing vector for studying DNA-protein interactions |
| Comments： | Restriction digests of the clone give the following sizes (kb): BglI--1.55, 1.25, 0.3, 0.24; EcoRI/HindIII--2.9, 0.27; XbaI--3.2. Recommendation for verification: EcoRI+HindIII--2.95, 0.25; BglI--1.9, 1.3; XbaI--3.2. Target DNA binding sites can be cloned into the vector and an array of fragments can be generated (by restriction digestion with different enzymes) that are equal in length, but differ in the position of the DNA binding site along the fragment. The reduced mobility of different protein-fragment complexes can then by analyzed by gel electrophoresis to determine the degree of bending induced by protein binding. One of three vectors (ATCC 87121-87123) designed for studying the amount of bending induced at a DNA binding site due to DNA-protein interactions. The three vectors differ only in the available cloning sites. Vector constructed from pBend3 (ATCC 87121) by addition of SalI and HpaI sites at the SalI site in the polylinker. |
