| Description | His6-rhTG4 is based on clone IMAGp958A10818Q2. It is N-terminally fused to a hexahistidine-tag resulting in the encoded N-terminal amino acid sequence MHHHHHHAEELLL…. His6-rhTG4 is produced in E. coli and purified by ion metal chelating chromatography to more than 95 % purity. |
| Produced in | Escherichia coli |
| Species | Human |
| Form | Recombinant |
| Gene ID | 7047 |
| Labelling | His-Tag |
| Preparation method | Add 10 mM Ca2+ to activate His6-rhTG4. |
| Molecular weight | 78 kDa |
| Principle | His6-rhTG4 catalyzes acyl transfer reactions from glutamine residues in proteins or peptides to primary amines, e. g. the formation of ε-(γ-glutamyl) lysine bonds between proteins by transferring the acyl group of a peptide-bound glutamine residue to the primary amino group of a peptide-bound lysine residue. His6-rhTG4 may also be used for immunoprecipitation. |
| Purity | > 95 % |
| Recommendations | Add the volume of H2O to the vial of lyophilized powder. Rotate vial gently until solid dissolves. After reconstitution the solution should be stored frozen in working aliquots. Keep cooled on ice for short term storage. |
| Product type | Proteins |
| Applications | Immunoprecipitation, Functional Assay |
| Research areas | Transglutaminase |

在免疫反应过程中,抗原加工细胞将静止的B细胞活化为浆细胞,以分泌针对该抗原的免疫球蛋白。从多个参与免疫反应的浆细胞克隆中,可以通过普通的细胞培养技术将每个分离。一旦分离,该细胞及其后代就会产生相同亚型的相同免疫球蛋白。这些免疫球蛋白于是被称为单克隆抗体,并且对所需抗原的一个表位具有相同的亲和力和特异性。
