Products IntroductionHyperProbe Mixture is a premixed system for real-time fluorescence quantitative PCR by probe method (TaqMan, Molecular Beacon, etc.). The concentration is 2×, which contains a new engineered DNA enzyme, PCR Buffer, dNTPs, Mg2+, enhancers and stabilizers, and it is easy to operate. It is mainly used for the detection of genomic DNA target sequences and cDNA target sequences after RNA reverse transcription.This product contains highly sensitive engineered DNA enzyme, which can effectively reduce the non-specific amplification caused by the non-specific binding of primers and templates or primer dimer at room temperature, and at the same time, greatly improve the detection sensitivity and amplification efficiency, and the activation of the enzyme only needs to be incubated at 95 ℃ for 30 s, which greatly shortens the reaction time of PCR. The optimized PCR buffer system and enzyme mixture effectively inhibit the generation of non-specific products, which can significantly improve the PCR amplification efficiency, stronger fluorescence signal and higher sensitivity. caveat1.

ROX dye is used to correct the fluorescence signal error generated between the wells of the quantitative PCR instrument, ROX is not contained in this product.If you need to match ROX dyes with your instrument, please contact your local sales office or call CombiSense customer service.4006-222-360. UsageThe following examples are conventional PCR reaction systems and conditions, which should be improved and optimized according to the template, primer structure and target fragment size. PCR reaction systemAttention:(1) Usually, a primer concentration of 0.2 M can give better results, and 0.1-1.0 µM can be used as a reference for setting the range. If the amplification efficiency is not high, the concentration of primer can be increased; if non-specific reaction occurs, the concentration of primer can be decreased to optimize the reaction system.(2) The final concentration of the probe used is related to the fluorescence quantitative PCR instrument used, the type of probe, and the type of fluorescent labeling substance, please refer to the manual of the instrument or the specific requirements for the use of each fluorescent probe to adjust the concentration.3) Usually the amount of DNA template is 10-100 ng of genomic DNA or 1-10 ng of cDNA as a reference, as templates of different speciesThe number of copies of the target gene contained in them varies, and a gradient dilution of the template can be performed to determine the optimal amount of template to use. PCR reaction conditions Attention:(1) The enzyme used in this product is activated by pre-denaturation at 95°C for 30 s. Most of the templates can be deconvoluted well under this condition. Under this condition, most of the templates can be well unchained. For templates with high GC content and complex secondary structure, the pre-denaturation time can be extended to 1 minute, so that the starting template can be fully unchained, and if the high temperature treatment time is too long, it will affect the activity of the enzyme; for simple templates, pre-denaturation can also be used for 20 s, and the optimal pre-denaturation time can be determined according to the template situation.(2) It is recommended to use two-step PCR program, the annealing temperature should be 58-64℃ as the reference range, and the annealing temperature can be increased when non-specific reaction occurs. If you can't get good results due to the use of primers with low Tm value, you can try three-step PCR amplification, and the annealing temperature should be set in the range of 56℃-64℃ as a reference. The annealing and extension times for several common instruments are shown in the following table: 20 s for Roche, BioRad, Agilent, Hongshi, Dongshenglong, etc. 30 s for ABI 7000/7300/7500. The annealing/extension times can be set according to the different types of instruments and templates, please follow the instructions of the instruments. The annealing/extension time can be set according to different models of instruments and templates, please follow the instruction manual of the instrument...

The human CD200 R1 cDNA encodes a 325 amino acid (aa) precursor that includes a 28 aa signal sequence, a 215 aa extracellular domain (ECD), a 21 aa transmembrane segment, and a 61 aa cytoplasmic domain. The ECD is composed of one Ig-like V-type domain and one Ig-like C2-type domain. Within the ECD, human CD200 R1 shares 56% aa sequence identity with both mouse and rat CD200 R1. Alternate splicing of the human CD200 R1 mRNA generates four isoforms, two of which are truncated in the Ig-C2 domain and are likely secreted. In human, a separate CD200 RL gene encodes a protein that shares 81% ECD aa identity with CD200 R1. In mouse, at least four genes for CD200 R1-like molecules have been described. CD200 R1 expression is restricted primarily to mast cells, basophils, macrophages, and dendritic cells, while its ligand, CD200, is widely distributed. Disruption of this receptor-ligand system by knockout of the CD200 gene in mice leads to increased macrophage number and activation and predisposition to autoimmune disorders. Association of CD200 with CD200 R1 takes place between their respective N-terminal Ig-like domains. The capacity of CD200 R1-like molecules to interact with CD200 is controversial. CD200 R1 propagates inhibitory signals despite lacking a cytoplasmic ITIM (immunoreceptor tyrosine-based inhibitory motif). CD200 R1-like molecules, in contrast, are potentially activating receptors by means of their association with DAP12. CD200R1 signaling inhibits the expression of proinflammatory molecules including TNFs, IFNs, and inducible nitric oxide synthase in response to selected stimuli, which implicate that CD200/CD200R1 inhibitory signaling pathway plays a prominent role in limiting inflammation in a wide range of inflammatory diseases. Furthermore, the CD200/CD200R inhibitory signaling constitutes one of the most suitable endogenous immunoregulatory molecule candidate to restore the immune suppressive status of the CNS altered in chronic neuroinflammatory situations...

HSPD1 may function as a signaling molecule in the innate immune system. This protein is essential for the folding and assembly of newly imported proteins in the mitochondria. It may also prevent misfolding and promote the refolding and proper assembly of unfolded polypeptides generated under stress conditions in the mitochondrial matrix. HSPD1 gene is adjacent to a related family member and the region between the 2 genes functions as a bidirectional promoter. Several pseudogenes have been associated with this gene. Mutations associated with this gene cause autosomal recessive spastic paraplegia 13. Defects in HSPD1 are a cause of spastic paraplegia autosomal dominant type 13 (SPG13). Spastic paraplegia is a degenerative spinal cord disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Defects in HSPD1 are the cause of leukodystrophy hypomyelinating type 4 (HLD4); also called mitochondrial HSP60 chaperonopathy or MitCHAP-60 disease. HLD4 is a severe autosomal recessive hypomyelinating leukodystrophy. HSPD1 is clinically characterized by infantile-onset rotary nystagmus, progressive spastic paraplegia, neurologic regression, motor impairment, profound mental retardation. Death usually occurs within the first two decades of life... Read More | Inquire |
