| Description | Storage buffer: 10mM Tris HCl, 5mM EDTA, 0.03% Bromophenol Blue, 0.03% Xylene Cyanol, 30% Glycerol, pH7.6Product IntroductionThis product is composed of 9 linear double stranded DNA fragments, stored in a 1xLoading Buffer, with dense bands that require high concentration gel and low voltage Storage buffer: 10mM Tris HCl, 5mM EDTA, 0.03% Bromophenol Blue, 0.03% Xylene Cyanol, 30% Glycerol, pH7.6Product IntroductionThis product is composed of 9 linear double stranded DNA fragments, stored in a 1xLoading Buffer, with dense bands that require high concentration gel and low voltage electrophoresis. It is suitable for accurately confirming the size of DNA fragments. The size range is 50-500bp, which are 50bp, 100bp, 150bp, 200bp, 250bp, 300bp, 350bp, 400bp, and 500bp respectively; 250 bp is the bright band, with a concentration 2.5 times that of other bands; In the 5 ul product, each strip contains about 40 ng, and the highlight strip contains about 100 ng.Usage suggestions1. It is recommended to sample 5 ul and increase the sample size appropriately for wide adhesive holes.2. It is recommended to use 2.5-3.5% Agarose or 5% PAGE gel, voltage 4-10 v/cm, and 0.5xTBE buffer for electrophoresis. Pay attention to replacing the electrophoresis buffer in time and using the newly prepared gel to achieve ideal results.3. Stain with EB or other nucleic acid dyes, and observe the electrophoretic bands under UV light.matters needing attention1. This product has been saved in a 1xLoading Buffer and can be directly used for electrophoresis. It is easy to use and the electrophoresis image is clear.2. When using agarose gel containing EB for electrophoretic detection, the bromophenol blue band can be electrophoretic to about 2/3 of the distance, otherwise the small segment will become dark because EB is separated from DNA.3. The accompanying 5xLoading buffer can be used for sample detection.5x Loading Buffer components:10 mM Tris-HCl，5 mM EDTA， pH7.6， 0.03% bromophenol blue, 0.03% xylene blue, 30% glycerol Product componentD745352Component100 T500TStorageD745352ADNA Ladder (50-500bp)500 µL5× 500 µL-20℃.

This combination of collagenolytic and proteolytic activities is effective at breaking down intercellular matrices, the essential Crude collagenase preparations contain several isoforms of two different collagenases, a sulfhydryl protease, clostripain, a trypsin-like enzyme, and an aminopeptidase. This combination of collagenolytic and proteolytic activities is effective at breaking down intercellular matrices, the essential part of tissue dissociation. One component of the complex is a hydrolytic enzyme which degrades the helical regions in native collagen preferentially at the Y-Gly bond in the sequence Pro-Y-Gly-Pro, where Y is most frequently a neutral amino acid. This cleavage yields products susceptible to further peptidase digestion. Crude collagenase is inhibited by metal chelating agents such as cysteine, EDTA or o-phenanthroline but not DFP. It is also inhibited by α2-macroglobulin, a large plasma glycoprotein. Ca2+ is required for enzyme activity. Particular enzymatic profiles of each collagenase have been correlated with the tissues from which the cells for study were obtained (or with the uses to which the cells are put) and as a result of the correlations several types of crude collagenases have been established by Aladdin: Types 1, 2, 3, and 4.This collagenase has been tested with cell lines to verify the product is not cytotoxic. Collagenase is typically used to digest the connective components in tissue samples to liberate individual cells. The concentration for cartilage dispersal is 1-2 mg/ml, but literature searches should be performed for species specific and/or tissue specific concentrations...

Acts as decoy receptor for RANKL and thereby neutralizes its function in osteoclastogenesis. Inhibits the activation of osteoclasts and promotes osteoclast apoptosis in vitro. Bone homeostasis seems to depend on the local RANKL/OPG ratio. May also play a role in preventing arterial calcification. May act as decoy receptor for TRAIL and protect against apoptosis. TRAIL binding blocks the inhibition of osteoclastogenesis.OPG has been applied to decrease bone resorption in women with postmenopausal osteoporosis and in patients with lytic bone metastases...
