Products Introduction This product is a premixed system consisting of a new high efficient fast DNA Polymerase, Mg2+, dNTPs, and PCR stabilizers and enhancers at 2× concentration. It is a new rapid DNA polymerase developed by CombiSigma with high amplification speed and stability. The extension speed is up to 5 s/kb, and the PCR can be completed in as little as 15 minutes, while longer fragments (>3 kb) or complex templates can be extended at a speed of 10-30 s/kb or a higher number of cycles. The unique MasterMix formula makes the whole reaction system very stable, while complex templates can be amplified effectively, and more than 98% of PCR amplification can be successful in one run. Simply add the DNA template and primers and top up with water to minimize human error, contamination and time.The dye (blue) has been added to the product and it is ready for electrophoretic detection at the end of the reaction. The PCR product is amplified with an 'A' base at the 3′ end and can therefore be used directly for T/A cloning and is suitable for use in the CombiVerge Seamless Cloning Kit, T4 Ligation Kit and sensory products.This product is mainly suitable for ultra-fast PCR, complex templates, complex secondary structures, gene cloning and large-scale genetic testing that requires high fidelity. quality control No exogenous nuclease activity was detected; no host residual DNA was detected by PCR; single-copy genes in various genomes could be amplified efficiently. UsageThe following is an example of a PCR reaction system and reaction conditions for amplifying a 1 kb fragment using human genomic DNA as a template, which should be improved and optimized according to the template, primer structure and size of the target fragment in actual operation.PCR reaction system Note: Please use the final concentration of 0.1-1.0 µM as a reference for setting the range of primer concentration. If the amplification efficiency is not high, the primer concentration can be increased; if a non-specific reaction occurs, the primer concentration can be decreased to optimize the reaction system.PCR reaction conditions Note: 1) Note: For simple templates, the pre-denaturation time can be controlled at 30 s-1 min, for complex templates such as bacterial fluids, the pre-denaturation time can be increased to 2 min.Optimization of parameter settings 1. Template DNA amount setting:Excessive amounts of template may result in non-specific amplification or smear. The recommended amount of template DNA in a 50 µl PCR reaction system is as follows:-Human genomic DNA 5 ng-500 ng-Escherichia coli genomic DNA 50 pg-100 ng-plasmid DNA 10 pg-1 ng 1. 30-35 number of cycles2. Primer concentration setting: The primer concentration can be set between 0.1 µM and 1.0 µM. A low primer concentration may result in low amplification products. Too high a primer concentration will inhibit specific amplification and may result in non-specific amplification.3. Annealing temperature setting: In general, the annealing temperature is 5℃ lower than the melting temperature of amplification primer Tm, so the annealing temperature can be lowered appropriately when the desired amplification efficiency cannot be obtained; the annealing temperature can be raised appropriately when non-specific reaction occurs. For complex templates, it is necessary to adjust the annealing temperature to achieve efficient amplification.4. Extension time setting: The extension time should be set according to the size of the amplified fragments. The following extension times are recommended: simple templates such as plasmids: 5-15 s/kb; regular genomes, cDNA templates: 10-15 s/kb; complex templates, crude templates: 20-30 s/kb; (the extension time should not be too short and should be at least 5 s/kb, but should not exceed 30 s/kb).5. Number of cycles: The number of cycles can be set according to the downstream application of the amplified product. If the number of cycles is too low, the amount of amplification will be insufficient; if the number of cycles is too high, the chance of mismatch will increase and the non-specific background will be serious. Therefore, the number of cycles should be minimized under the premise of ensuring the product yield...

Both MCP-2 and CCL7 are members of the C-C family of chemokines and share 62% and 71% amino acid sequence identity, Purity:>95%, by SDS-PAGE visualized with Coomassie® Blue StainingDescription:MCP-2 and CCL7 are two monocyte chemotactic proteins produced by human MG-63 osteosarcoma cells. Both MCP-2 and CCL7 are members of the C-C family of chemokines and share 62% and 71% amino acid sequence identity, respectively, with MCP-1. CCL7 also shares 58% amino acid identity with MCP-2. CCL7 cDNA encodes a 99 amino acid residue precursor protein from which the N-terminal 23 amino acid residues are cleaved to generate the 76 amino acid residue mature CCL7. Mature CCL7 contains a potential N-linked and several possible O-linked glycosylation sites. Similarly to other C-C chemokines, all three MCP proteins are monocyte chemoattractants. In addition, the three MCPs can chemoattract activated NK cells as well as CD4+ and CD8+ T lymphocytes. All three cytokines have also been shown to attract eosinophils and induce histamine secretion from basophils... Read More | Purity>97% SDS-PAGE and HPLC analyses.

NAP-2 is a ligand for CXCR1 and CXCR2, and NAP-2, NAP-2(73), NAP-2(74), NAP-2(1-66), and most potent NAP-2(1-63) are chemoattractants and activators for neutrophils. TC-1 and TC-2 are antibacterial proteins, in vitro released from activated platelet alpha-granules. CTAP-III(1-81) is more potent than CTAP-III desensitize chemokine-induced neutrophil activation.Post-translationalProteolytic removal of residues 1-9 produces the active peptide connective tissue-activating peptide III (CTAP-III) (low-affinity platelet factor IV (LA-PF4)). Proteolytic removal of residues 1-13 produces the active peptide beta-thromboglobulin, which is released from platelets along with platelet factor 4 and platelet-derived growth factor. NAP-2(1-66) is produced by proteolytical processing, probably after secretion by leukocytes other than neutrophils. NAP-2(73) and NAP-2(74) seem not be produced by proteolytical processing of secreted precursors but are released in an active form from platelets... Read More |
