ABclonal Technology T3 DNA Ligase
T3 DNA Ligase is an ATP-dependent ds DNA ligase from bacteriophage T3. It can catalyze the formation of a phosphodiester bond between juxtaposed 5 phosphate and 3 hydroxyl termini in duplex DNA or RNA. T3 DNA Ligase will join blunt end and cohesive end termini. It and can also repair single-stranded nicks in duplex DNA, RNA or DNA/RNA hybrids and close the gaps in these DNA substrates. In addition, T3 DNA Ligase is more tolerant to NaCl than T4 DNA Ligase (2-fold). As with T4 DNA Ligase , addition of PEG 6000 to the T3 DNA Ligase reaction system can improve the ligation efficiency of the blunt end. 1X T4 DNA Ligase Reaction Buffer can be used in some experiments where PEG 6000 is not available, but the activity of T3 DNA Ligase is reduced to 1/10. In applications where high concentrations of NaCl need to be maintained, we recommend the use of reaction buffers without PEG 6000.

Bachem Bz-Nle-Lys-Arg-Arg-AMC
Bz-Nle-Lys-Arg-Arg-AMC Trifluoroacetate, 863975-32-0, C41H60N12O7, Mr 833.00, 1mg. Substrate for dengue virus NS2B-NS3 and yellow fever virus NS3 protease. The kcat/Km value of Bz-NleKRR-AMC for the dengue virus type 4 (DEN4) enzyme is > 800 fold higher than that of Boc-Gly-Arg-Arg-AMC, a widely used NS3 substrate (kcat = 2.9 s-1, Km = 8.6 μM for DEN4). For yellow fever virus NS3 protease the kcat value was 0.111 s-1, the Km value 14.6 μM.

ILEX LIFE SCIENCES LLC Ilex Life Sciences L-Asparaginase, E. coli Enzyme, Bioactive, 500 IU
Our high-purity, bioactive L-Asparaginase enzyme is purified from E. coli ASI.357. Purity: greater than 96%. Formulation: Lyophilized with no additives. Summary: L-Asparaginase is an enzyme that depletes L-Asparagine, an important nutrient for cancer cells, resulting in cancer/tumor cell starvation. The rationale behind asparaginase is that it takes advantage of the fact that acute lymphoblastic leukemia cells and some other suspected tumor cells are unable to synthesize the non-essential amino acid asparagine, whereas normal cells are able to make their own asparagine; thus leukemic cells depend on circulating asparagine. Asparaginase, however, catalyzes the conversion of L-asparagine to aspartic acid and ammonia. This deprives the leukemic cell of circulating asparagine, which leads to cell death. Synonyms: L-ASNase, L-asparagine amidohydrolase, ansA.
LifeSensors SUMO Protease 1 250 Units
LifeSensors' industry leading SUMO Protease 1 (Ulp1), a highly active and robust recombinant protease, cleaves SUMO from recombinant fusion proteins. Unlike thrombin, EK, or TEV protease, which recognize short linear sequences, SUMO Protease 1 recognizes the tertiary structure of SUMO. As a result, SUMO Protease 1 will not cleave within the fused protein of interest. 1 unit will cleave >90 µg of hSUMO3-GFP in 1 hr at 37C.
LifeSensors SUMO PROTEASE 2 500 UNITS
For removal of SUMOpro3 tags from fusion proteins expressed from the following SUMOpro3 expression systems: (Cat.#s: 1010A, 1016, 1010K, 1011, 2151). SUMO Protease 2, a highly active and robust recombinant protease, cleaves hSUMO3 from recombinant fusion proteins. Unlike thrombin, EK, or TEV protease, which recognize short, linear sequences, SUMO Protease 2 recognizes the tertiary structure of huSUMO3. As a result, SUMO Protease 2 will not cleave within the fused protein of interest. By purchasing this product, the purchaser agrees to comply with the terms of our Limited Use Label License.
