United States Biological Corporation ZYMOLYASE 100T 50MG
Zymolyase, produced by a submerged culture of Arthrobacter luteus (1), is an enzyme preparation which effectively lyses cell walls of viable yeast cells. An essential enzyme responsible for lysis of viable yeast cells in this preparation is b-1, 3-glucan laminaripentaohydrolase. It hydrolyzes linear glucose polymers with b-1,3-linkages and releases laminaripentaose specifically as the main and minimum product unit (4,5,10,11). This lytic activity releases spheroplasts and protoplasts in the preparation of yeast DNA prior to restriction enzyme digestion and Southern Blot analysis. The extent of lysis of yeast cells by Zymolyase varies with yeast strain, growth stage of yeast and cultural condition (6-8). Further information related to Zymolyase is obtained in the references below.

Apexbio Technology LLC Amyloid β-Peptide (1-42) (human),1mg CAS# 107761-42-2
Amyloid β-Peptide (1-42) (Aβ42) human is a 42-amino acid peptide that plays a key role in the pathogenesis of Alzheimer disease (AD) [1].The main deleterious effects in the pathogenesis are probably regulated by Aβ42, which acts as a repressor or activator of gene transcription causing further synaptic function damage and neuronal degeneration [2].Aβ42 reduced the viability of SH-SY5Y cells to 65% when it rose to 2.5 μM. Using the chromatin immunoprecipitation (ChIP) and qRT-PCR assays, treatment of SH-SY5Y cells with Aβ42 associated peptide with both LRP1 and KAI1 promoters and increased APP mRNA levels, while the nontoxic Aβ42 G33A peptide, as a control group which presents in the nucleus abundantly, did not have any influence on mRNA expression. The exclusive increase of transcription and expression of its precursor gene APP was found with the treatment of Aβ42, compared with several different lengths of peptides [1].

Apexbio Technology LLC DNase I (RNase-free) 10000U
DNase I (RNase-free) is an endodeoxyribonuclease capable of hydrolyzing single-stranded or double-stranded DNA producing dinucleotide trinucleotide and oligonucleotide fragments with 3 -OH and 5 -phosphate ends The activity of DNase I (RNase-free) depends on Ca2 and can be activated by Mg2 or Mn2 In the presence of Mg2 DNase I (RNase-free) randomly cleaves double-stranded DNA at any site in the presence of Mn2 it simultaneously recognizes both DNA strands and cleaves at nearly identical sites DNase I (RNase-free) acts on single-stranded DNA double-stranded DNA chromatin and RNA DNA hybrids In molecular biology experiments DNase I (RNase-free) is suitable for the removal of DNA in RNA extraction in vitro transcription and RT-PCR applications
Apexbio Technology LLC DNase I (RNase-free),1000U
DNase I (RNase-free) is an endonuclease that digests single- or double- stranded DNA, generating dinucleotide, trinucleotide, and oligonucleotide products with 5´-phosphorylated and 3´-hydroxylated ends. The activity of DNase I (RNase-free) dependent on Ca2+ and can be activated by Mg2+ or Mn2+. In the presence of Mg2+, DNase I (RNase-free) can randomly cleaves arbitrary sites of double-stranded DNA; in the presence of Mn2+, DNase I (RNase-free) can simultaneously recognize both strands of DNA and cleaves at nearly same sites. DNase I (RNase-free) can act on single stranded DNA, double stranded DNA, chromatin, and RNA: DNA hybrid strands. DNase I (RNase-free) is suitable for RNA extraction, in vitro transcription, and removal of DNA for RT-PCR experiments.Other sizes are also available. Please inqury us for quote.

LifeSensors SUMO PROTEASE 2 250 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.
