Avoid freeze/thaw cycle.Product IntroductionThis product is a premixed system composed of Super Kfx DNA Polymerase, Mg2+, dNTPs, PCR stabilizers and enhancers, with a concentration of 2 ×. Super Kfx DNA Polymerase is a fast and highly efficient high fidelity DNA polymerase with 5 ′ -3 ′ DNA polymerase activity and 3 ′ -5 ′ exonuclease activity. It has advantages such as strong amplification ability, high fidelity, and strong specificity. The addition of unique amplification enhancers and elongation factors in 2xMix results in a unique formula that makes the entire reaction system very stable, easy to operate, and suitable for amplification of various fragments and templates. This product is suitable for gene cloning, second-generation library amplification, gene directed mutagenesis, SNP amplification experiments, etc. This product has been added with dye (blue), and after the reaction is completed, agarose electrophoresis detection can be directly performed, making the operation convenient and simple. Quality controlAfter testing, there is no exogenous nuclease activity and no residual host DNA, which can effectively amplify various templates. UsageThe following are examples of conventional PCR reaction systems and reaction conditions. In practical operation, corresponding improvements and optimizations should be made based on different templates, primer structures, and target fragment sizes.1. PCR reaction systemAll operations should be carried out on ice. After each group is decomposed and frozen, please mix thoroughly. After use, please put it back at -20 ℃ for storage in a timely manner. 2. PCR reaction conditions Attention:1) Priority should be given to using the three-step method for amplification. If the three-step method cannot amplify the target product or the Tm value of the primer is greater than 68 ° C, please try the two-step method.2) Denaturation: Pre denaturation of simple templates at 98 ℃ for 30 seconds to 1 minute. For complex templates, the pre denaturation time can be extended to 3 minutes.3) Annealing: In general experiments, the annealing temperature is 3-5 ℃ lower than the Tm value of the primer. If the ideal amplification efficiency cannot be achieved, the annealing temperature should be gradually changed for optimization; When non-specific reactions occur, increase the annealing temperature appropriately.4) Extension: The extension time should be set based on the length of the amplified fragment and the complexity of the template. The amplification efficiency of this product is 4-6 kb/min. For long fragments and high complexity templates, it is recommended to set 2-4 kb/min.5) Cycle count: The number of cycles can be set based on the downstream application of the amplification product. If there are too few cycles, insufficient amplification, or too many cycles, the probability of mismatch will increase. Therefore, while ensuring product yield, the number of cycles should be minimized as much as possible...

It belongs to a family of membrane-bound glycoproteins that are involved in Ca++ independent cell matrix and homophilic or heterophilic cell-cell interactions. NCAM-1 specifically binds to heparan sulfate proteoglycans, the extracellular matrix protein agrin, and several chondroitin sulfate proteoglycans that include neurocan and phosphocan. There are three main forms of human NCAM-1 that arise by alternate splicing. These are designated NCAM-120/NCAM-1 (761 amino acids [aa]), NCAM‑140 (848 aa), and NCAM-180 (1120 aa). NCAM-120 is GPI-linked, while NCAM‑140 and NCAM-180 are type I transmembrane glycoproteins. Additional alternate splicing adds considerable diversity to all three forms, and extracellular proteolytic processing is possible for NCAM-180. NCAM-1 is synthesized as a 761 aa preproprecursor that contains a 19 aa signal sequence, a 722 aa GPI-linked mature region, and a 20 aa C-terminal prosegment. The molecule contains five C-2 type Ig-like domains and two fibronectin type-III domains. Human to mouse, NCAM-1 is 93% aa identical. NCAM-1 appears to be highly sialylated. The polysialyation of NCAM-1 reduces its adhesive property and increases its neurite outgrowth promoting features. NCAM-1 in the adult brain shows a decline of sialylation relative to earlier developmental periods. In regions that retain a high degree of neuronal plasticity, however, the adult brain continues to express polysialylation-NCAM-1, suggesting sialylation of NCAM-1 is involved in regenerative processes and synaptic plasticity...

Its main physiological function is to regulate plasma pH and maintain plasma osmotic pressure.Osrhsa (recombinant human serum albumin from Oryza sativa) is a recombinant human serum albumin developed by using rice endosperm cell expression platform (oryzhiexp) and purification platform (oryzpur). It does not contain animal derived ingredients and can eliminate the risk of blood derived virus infection. Compared with fetal bovine serum (FBS), plasma derived albumin (pHSA) and bovine serum albumin (BSA), osrhsa has higher purity and better batch stability. It can be used in various research fields, including biopharmaceutical, cell therapy and cell culture of gene therapy. It can replace serum and promote cell growth. At the same time, osrhsa is also widely used in biomedical production as drug carrier, vaccine protector, cell cryoprotectant and medical device embedding agent.ApplicationBiopharmaceuticals, human vaccines, cell culture, cell storage, chemical drug molecular carriers, medical devices, in vitro diagnosis, etc.Comparison of physical and chemical properties between OsrHSA and natural human white pHSAphysicochemical propertiespHSAOsrHSAamino acid sequenceagreementN-terminal amino acidsDAHKSEVDAHKSEVC-terminal amino acidsKLVAASQAALGLKLVAASQAALGLGlycoside modificationnothingmolecular weight (MALDl)66.554 (kDa)66.550 ( a)Isoelectric point (pl)4.84.8Drug binding activityclosethermal stabilitymp 65℃mp 65℃esterase activityidenticalcrystal structureidenticalRestrictions on use:The above products are only suitable for scientific research, laboratory and production use, and cannot be directly used in human body...
