The kit is designed to measure calcium directly in biological samples without any pretreatment. A phenolsulphonephthalein dye in the kit forms a very stable blue colored complex specifically with free calcium. The intensity of the color, measured at 612 nm, is directly proportional to the calcium concentration in the sample. The optimized formulation minimizes any interference by substances such as magnesium, lipid, protein and bilirubin.\u003cbr\u003e\nSensitive and accurate.\u003cbr\u003e\nUse as little as 5 μL samples. Linear detection range 0.08 mg\/dL (20 μM) to 20 mg\/dL (5 mM) Ca\u003cbr\u003e\nin 96-well plate assay.\u003cbr\u003e\nSimple and high-throughput.\u003cbr\u003e\nThe procedure involves addition of a single working reagent and incubation for 3 min. Can be readily automated as a high-throughput assay for thousands of samples per day.\u003cbr\u003e\nImproved reagent stability and versatility\u003cbr\u003e\n. The optimized formulation has greatly enhanced reagent and signal stability. Cuvet or 96-well plate assay.\u003cbr\u003e\nLow interference in biological samples\u003cbr\u003e\n. No pretreatments are needed. Assays can be directly performed on raw biological samples i.e., in the presence of lipid, protein and minerals such as magnesium, iron and zinc.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Ambient - Can Ship with Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nCalcium ions (Ca²⁺) serve as essential signaling molecules in various cellular processes. These ions have an atomic mass number of 40.08. Calcium ions are highly concentrated in bone tissues teeth and within cells mostly stored in the endoplasmic reticulum and mitochondria. Common indicators of calcium concentration in research include the use of dyes such as Fura-2 and Calbryte 520 AM. These indicators help in visualizing the transient increases in intracellular calcium levels which are important in cellular signaling.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nCalcium ions mediate various physiological functions including muscle contraction neurotransmitter release and hormone secretion. They typically do not act as lone agents; instead they often function as part of protein complexes particularly with calcium-binding proteins like calmodulin and troponin C. Calcium ions also interact with enzymes such as protein kinases and phosphatases regulating metabolic pathways and genetic expression.\u003cbr\u003e\nPathways\u003cbr\u003e\nCalcium ions play pivotal roles in the calcium signaling pathway and the cardiac excitation-contraction coupling pathway. In the calcium signaling pathway calcium ions once released from stores like the endoplasmic reticulum activate proteins such as calmodulin which then modulates various cellular activities. In the cardiac excitation-contraction coupling pathway calcium bows its link to proteins like sarcoplasmic reticulum calcium ATPase essential for heart muscle function.\u003cbr\u003e\nCalcium ion dysregulation can lead to conditions such as osteoporosis and cardiac arrhythmias. In osteoporosis low calcium levels contribute to decreased bone density affecting bone health and making them prone to fractures. In cardiac arrhythmias abnormal calcium handling can result in irregular heartbeats. Proteins such as calbindin-D28k are closely connected to calcium metabolism disorders highlighting the significance of calcium in maintaining physiological balance.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46855626883241,"sku":"ab272527","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab272527","provider":"Iright","version":"1.0","type":"link"}
