In the case of low amplification efficiency, the concentration of primers can be increased; When non-specific reactions occur, the primer concentration can be reduced to optimize the reaction system.2.

The amplification efficiency of Taq DNA Polymerase in this product is 2 kb/min.3) The number of cycles can be set based on the downstream application of the amplification product. If the number of cycles is too small, the amplification amount is insufficient; If there are too many cycles, the probability of mismatches will increase, and non-specific backgrounds will be severe. So, while ensuring product yield, the number of cycles should be minimized as much as possible...

Purity:>98%, by SDS-PAGE visualized with Coomassie® Blue Staining.Description：Heme oxygenase (HMOX) is the rate limiting enzyme in heme catabolism. It cleaves heme to biliverdin, carbon monoxide, and iron. The biliverdin is subsequently converted to bilirubin by biliverdin reductase. The mechanism of HMOX is unique in that heme serves as the substrate of the enzyme and as the prosthetic group for the activation of iron-bound O2. HMOX activity is highest in spleen where senescent erythrocytes are sequestered and destroyed. Two isoforms, HMOX1 and HMOX2, are expressed in most tissues. HMOX1 is an inducible enzyme in response to heme, heavy metals, oxidative stress, cytokines, and many drugs. Whereas HMOX2 displays a constitutive expression. HMOX1 is expressed mainly in spleen, liver, and kidney, and HMOX2 is prominently expressed in the brain and testes. The increased expression of HMOX1 levels is related to a variety of pathological states, where it functions as a cytoprotective molecule through its by products. HMOX1 also plays important roles in the regulation of cell proliferation, differentiation, and apoptosis... Read More |
