Fluo-4 Direct™ Calcium Assay Kit는 다음과 같은 균일한 형광 칼슘 분석을 제공하도록 구성되었습니다.
1. 세포로의 손쉬운 loading
2. 넓은 분석 허용범위
3. 특정 세포 형광에 거의 영향을 미치지 않고 완전한 배지에서 칼슘 표지자로 야기되는 background 형광 차단

개선된 formulation은 혈청 함유 배지에서도 첨가만 하면 되는 형식으로 분석을 간편하게 합니다. Fluo-4 Direct™는 Fluo-4 칼슘 검출 시약군의 세번째로 개발된 제품입니다. Fluo-4 AM 및 Fluo-4 NW는 모두 검출 분석 전 배지를 제거해야 하나 Fluo-4 NW는 편리함을 더해 PowerLoad™ 시약을 세포 loading에 첨가하기만 하면 됩니다. Fluo-4 Direct™ Calcium Assay Kit는 손쉬운 세포 loading을 위해 PowerLoad™로 만들어졌다는 면에서 Fluo-4 NW와 비슷하지만 완전 배양 배지(complete media)에 사용할 수 있고 분석에서 발생하는 특정 세포 형광을 희생시키지 않고 효율적으로 background 형광을 차단할 수 있다는 특징을 갖습니다.

자주 묻는 질문(FAQ)

I am doing calcium flux imaging with your Fura-2 calibration kit, but am seeing a large variability in ratio in different places around the slide. I am correcting for uniform illumination, using the product as directed, and sealing the coverslip with nail polish.

The nail polish may be the problem. The Kd value (calcium sensitivity) changes depending upon the dye's environment. Nail polish has solvents that can leech under the coverslip and cause variability. We recommend either going without a sealing or sealing with melted paraffin painted on the coverslip edges with a cotton-tipped applicator (paraffin is hydrophobic and has no solvents).

I need to label cells with Fluo-4, AM, for a calcium flux assay. How long after labeling will the dye be retained?

After loading dye into the cells, intracellular esterases remove the 'AM' moiety from the dye. When the 'AM' group is removed, the dye is able to bind calcium and fluoresce. Since the dye is not covalently bound to any cellular components, it may be actively effluxed from the cell. The rate of efflux is dependent upon the inherent properties of the cell, culture conditions and other factors. The dye may be retained for hours, days or even weeks or lost in a matter of minutes. The use of Probenecid (Cat. No. P36400) limits loss by active efflux.

Abstract
High-resolution imaging of the immunological synapse and T-cell receptor microclustering through microfabricated substrates.
Authors:Biggs MJ, Milone MC, Santos LC, Gondarenko A, Wind SJ,
Journal:J R Soc Interface
PubMed ID:21490003
'T-cell activation via antigen presentation is associated with the formation of a macromolecular membrane assembly termed the immunological synapse (IS). The genesis of the IS and the onset of juxtacrine signalling is characterized by the formation of cell membrane microclusters and the organization of such into segregated microdomains. A central ... More
Regulation of cytosolic phospholipase A2 (cPLA2alpha) and its association with cell proliferation in human lens epithelial cells.

'To investigate the molecular mechanism for cytosolic phospholipase A2 (cPLA(2)a) regulation and its association to platelet-derived growth factor (PDGF)-induced cell proliferation. cPLA(2)a was examined using human lens epithelial (HLE) B3 cells. Reactive oxygen species (ROS) generation induced by PDGF was analyzed by luminescence assay. Cell proliferation was measured by cell ... More
20-Hydroxyeicosatetraenoic acid (20-HETE) is a novel activator of transient receptor potential vanilloid 1 (TRPV1) channel.
Authors:Wen H, Östman J, Bubb KJ, Panayiotou C, Priestley JV, Baker MD, Ahluwalia A,
Journal:J Biol Chem
PubMed ID:22389490
'TRPV1 is a member of the transient receptor potential ion channel family and is gated by capsaicin, the pungent component of chili pepper. It is expressed predominantly in small diameter peripheral nerve fibers and is activated by noxious temperatures >42 °C. 20-Hydroxyeicosatetraenoic acid (20-HETE) is a cytochrome P-450 4A/4F-derived metabolite ... More
Gq/5-HT2c receptor signals activate a local GABAergic inhibitory feedback circuit to modulate serotonergic firing and anxiety in mice.
Authors:Spoida K, Masseck OA, Deneris ES, Herlitze S,
Journal:
PubMed ID:24733892
Serotonin 2c receptors (5-HT2c-Rs) are drug targets for certain mental disorders, including schizophrenia, depression, and anxiety. 5-HT2c-Rs are expressed throughout the brain, making it difficult to link behavioral changes to circuit specific receptor expression. Various 5-HT-Rs, including 5-HT2c-Rs, are found in the dorsal raphe nucleus (DRN); however, the function of ... More
Small molecule inhibition of PAX3-FOXO1 through AKT activation suppresses malignant phenotypes of alveolar rhabdomyosarcoma.
Authors:Jothi M, Mal M, Keller C, Mal AK,
Journal:
PubMed ID:24107448
Alveolar rhabdomyosarcoma comprises a rare highly malignant tumor presumed to be associated with skeletal muscle lineage in children. The hallmark of the majority of alveolar rhabdomyosarcoma is a chromosomal translocation that generates the PAX3-FOXO1 fusion protein, which is an oncogenic transcription factor responsible for the development of the malignant phenotype ... More
