| Description | DescriptionAladdin provides purified Human Tyrosyl DNA Phosphodiesterase (Tdp1) purified to homogeneity to a single 68 kDa band on SDS-PAGE. Tdp1 is catalytically active and will remove a terminal 3’ phosphotyrosyl group from a specifically designed oligo target site (oligo-Tyr). Additionally,DescriptionAladdin provides purified Human Tyrosyl DNA Phosphodiesterase (Tdp1) purified to homogeneity to a single 68 kDa band on SDS-PAGE. Tdp1 is catalytically active and will remove a terminal 3’ phosphotyrosyl group from a specifically designed oligo target site (oligo-Tyr). Additionally, Aladdin scientists have demonstrated that Tdp1 will release topo I covalently attached to genomic DNA isolated from cells treated with camptothecin using Aladdin’s In Vivo Link Kit. Tdp1 is thought to be important in repair of topo/DNA adducts that form following topo-active drug therapy; therefore, there is considerable interest in identifying drugs that target Tdp1. Such drugs may work well in combination with topo targeting strategies.Figure 1. SDS-PAGE of Aladdin Purified Tdp1. The gel was intentionally overloaded with 20ug of protein to reveal minor breakdown products.Droduction infoUnit Defintion:One unit of Tdp1 can release the terminal Tyrosine from 20 ng of substrate (oligo-Tyr) in 30 min at 37° C.Tdp1 Reaction:Release of topo I from the covalent complex is shown below.Tdp1 Assays:Biochemical assays for Tdp1 can be carried out using an oligo nucleotide with a 3’ terminal tyrosine residue. Release of tyrosine from a 5’ 32P end labeled oligo is easily measured using a denaturing polyacrylamide gel or DNA sequencing gels.

HLA-DRA binds peptides derived from antigens which access the endocytic route of antigen presenting cells (APC) Purity: >90%, by SDS-PAGE visualized with Coomassie® Blue Staining. Description: Major histocompatibility complex, class II, DR alpha (HLA-DRA) belongs to the MHC class II family. HLA-DRA binds peptides derived from antigens which access the endocytic route of antigen presenting cells (APC) and presents them on the cell surface for identification by the CD4 T-cells. The peptide binding cleft accommodates peptides of 10-30 residues. The peptides presented by MHC class II molecules are generated mainly by degradation of proteins which access the endocytic route, where they are processed by lysosomal proteases and other hydrolases...
