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... Read More | GoldStar Probe Mixture is a premixed system specifically designed for real-time fluorescence quantitative PCR using probe methods (TaqMan, Molecular Beacon, etc.), with a concentration of 2 x, containing GoldStar Taq DNA Polymerase, PCR Buffer, dNTPs, and Mg2+. The operation is simple and convenientGoldStar Probe Mixture is a premixed system specifically designed for real-time fluorescence quantitative PCR using probe methods (TaqMan, Molecular Beacon, etc.), with a concentration of 2 x, containing GoldStar Taq DNA Polymerase, PCR Buffer, dNTPs, and Mg2+. The operation is simple and convenient. Mainly used for detecting genomic DNA target sequences and RNA reverse transcription cDNA target sequences, such as gene expression analysis, copy number analysis, SNP genotype analysis, etc., suitable for fluorescence quantification using different types of probe methods. The GoldStar Taq DNA Polymerase contained in this product is a chemically modified, novel and highly efficient hot start enzyme. It has no polymerase activity at room temperature, effectively avoiding non-specific amplification caused by non-specific binding of primers and templates or primer dimerization at room temperature. The enzyme activation requires incubation at 95 ℃ for 10 minutes. The unique combination of PCR buffer system and hot start enzyme significantly improves the amplification efficiency of PCR, with stronger fluorescence signal and higher sensitivity, which can detect single copy templates. By using this product, a wider linear range can be obtained, resulting in more accurate quantification of the target gene. Suitable for all fluorescence quantitative PCR instruments that do not require ROX as a calibration dye.ROX dye is used to correct the fluorescence signal error between wells in quantitative PCR instruments, and is generally used in Real Time PCR amplification instruments from companies such as ABI and Stratagene. The excitation optical systems of different instruments vary, so the concentration of ROX dye must be matched with the corresponding fluorescence quantitative PCR instrument.Instruments that do not require ROX calibration (CW0932): Roche LightCycle 480, Roche LightCyler 96, Bio rad iCyler iQ, iQ5, CFX96, etc.Instrument requiring Low ROX calibration (CW2625): ABI Prism7500/7500 Fast, QuantStudio ® 3 System, QuantStudio ® 5 System, QuantStudio ® 6 Flex System, QuantStudio ® 7 Flex System, ViiA 7 System, Stratagene Mx3000/Mx3005P, Corbett Rotor Gene 3000, etc.Instruments that require High ROX calibration (CW2626): ABI Prism7000/7300/7700/7900, Eppendorf, ABI Step One/Step One Plus, etc.G665832Component5 mLStorageG665832A2×GoldStar Probe Mixture5×1 mL-20℃.

Please refer to the instrument manual or the specific usage requirements of each fluorescent probe for concentration adjustment during actual use.3) The amount of DNA template is usually based on 10-100 ng genomic DNA or 1-10 ng cDNA as a reference. Due to the different copy numbers of target genes contained in templates of different species, gradient dilution can be applied to the template to determine the optimal template usage.4) The excitation optical systems of different instruments vary, and depending on the instrument used for fluorescence quantification, 50 x Low ROX or 50 x High ROX can be added.2.

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.

IAP family members usually contain multiple baculovirus IAP repeat (BIR) domains, but BIRC5 has only a single BIR domain. It is expressed cell cycle-dependently and highly expressed at mitosis. As a multitasking protein, BIRC5 has dual roles in promoting cell proliferation and preventing apoptosis. Survivin is a component of a chromosome passage protein complex (CPC) which is essential for chromosome alignment and segregation during mitosis and cytokinesis. Survivin acts as an important regulator of the localization of this complex. It may counteract a default induction of apoptosis in G2/M phase... Read More |
