What are the fluorescence excitation/emission maxima for the dyes contained in the Mitochondrial Membrane Potential Apoptosis Kit, with Mitotracker Red & Alexa Fluor 488 annexin V, for flow cytometry
I want to study apoptosis using an Annexin V conjugate, but with adherent cells via microscopy instead of flow cytometry. Can this be done?
It has been done, but we dont recommend it. Both healthy cells and apoptotic cells possess phosphatidylserine on the cell surface, which can be detected with Annexin V, but apoptotic cells have significantly more of it. You can easily tell the difference between these two populations with flow cytometry, because flow cytometers are more sensitive and have a higher throughput. But with a microscope, you cannot always tell the difference, especially for adherent cells. Instead, for microscopy, we recommend a different technique, such as detecting caspases with CellEvent Caspase Detection Reagents.
Galectin 1 modulates plasma cell homeostasis and regulates the humoral immune response.

'Galectin-1 (GAL1) is an S-type lectin with multiple functions, including the control of B cell homeostasis. GAL1 expression was reported to be under the control of the plasma cell master regulator BLIMP-1. GAL1 was detected at the protein level in LPS-stimulated B cells and was shown to promote Ig secretion ... More
FGF23 activates injury-primed renal fibroblasts via FGFR4-dependent signalling and enhancement of TGF-ß autoinduction.

Bone-derived fibroblast growth factor 23 (FGF23) is an important endocrine regulator of mineral homeostasis with effects transduced by cognate FGF receptor (FGFR)1-a-Klotho complexes. Circulating FGF23 levels rise precipitously in patients with kidney disease and portend worse renal and cardiovascular outcomes. De novo expression of FGF23 has been found in the ... More
High Tidal Volume Induces Mitochondria Damage and Releases Mitochondrial DNA to Aggravate the Ventilator-Induced Lung Injury.

This study aimed to determine whether high tidal volume (HTV) induce mitochondria damage and mitophagy, contributing to the release of mitochondrial DNA (mtDNA). Another aim of the present study was to investigate the role and mechanism of mtDNA in ventilator-induced lung injury (VILI) in rats. ... More
Adaptive phenotypic modulations lead to therapy resistance in chronic myeloid leukemia cells.

Tyrosine kinase inhibitor (TKI) resistance is a major problem in chronic myeloid leukemia (CML). We generated a TKI-resistant K562 sub-population, K562-IR, under selective imatinib-mesylate pressure. K562-IR cells are CD34-/CD38-, BCR-Abl-independent, proliferate slowly, highly adherent and form intact tumor spheroids. Loss of CD45 and other hematopoietic markers reveal these cells have ... More
