My DAPI labeled samples have a strong blue background signal immediately after mounting. What can I do to fix this?
Some mounting medias can have strong blue autofluorescence. If you are seeing a high blue background, it could be coming from the mountant. Try labeling the sample and view it before (using a wet mount in buffer) and after mounting to determine if the background signal is coming from the mounting media or the sample itself.
Do you offer an alternative for the discontinued 3-Germ Layer ICC Kit (Cat. No. A25538)?
We do not have a direct alternative for the discontinued 3-Germ Layer ICC Kit (Cat. No. A25538). However, we do have alternative primary and secondary antibodies, as well as reagents, that can be used for trilineage differentiation. Please note that we have not internally validated the use of all these reagents together.
Can I use the ReadyProbes reagents for flow cytometry?
This is not recommended. The ReadyProbes reagents were developed for imaging applications whereas the Ready Flow reagents were optimized for flow cytometry.
Multipotent stem cells from trabecular meshwork become phagocytic TM cells.
Authors:Du Y, Roh DS, Mann MM, Funderburgh ML, Funderburgh JL, Schuman JS,
Journal:Invest Ophthalmol Vis Sci
PubMed ID:22297497
'To isolate and characterize stem cells from human trabecular meshwork (TM) and to investigate the potential of these stem cells to differentiate into TM cells. Human trabecular meshwork stem cells (TMSCs) were isolated as side population cells by fluorescence-activated cell sorting or isolated by clonal cultures. Passaged TMSCs were compared ... More
Transitions of protein traffic from cardiac ER to junctional SR.
Authors:Sleiman NH, McFarland TP, Jones LR, Cala SE,
Journal:
PubMed ID:25640161
'The junctional sarcoplasmic reticulum (jSR) is an important and unique ER subdomain in the adult myocyte that concentrates resident proteins to regulate Ca(2+) release. To investigate cellular mechanisms for sorting and trafficking proteins to jSR, we overexpressed canine forms of junctin (JCT) or triadin (TRD) in adult rat cardiomyocytes. Protein ... More
DNA polymerase ß-dependent cell survival independent of XRCC1 expression.

PubMed ID:25541391
'Base excision repair (BER) is a primary mechanism for repair of base lesions in DNA such as those formed by exposure to the DNA methylating agent methyl methanesulfonate (MMS). Both DNA polymerase ß (pol ß)- and XRCC1-deficient mouse fibroblasts are hypersensitive to MMS. This is linked to a repair deficiency ... More
Co-storage and secretion of growth hormone and secretoneurin in retinal ganglion cells.
Authors:Martinez-Moreno CG, Trudeau VL, Harvey S,
Journal:
PubMed ID:25435278
'It is well established that growth hormone (GH) and granins are co-stored and co-secreted from pituitary somatotrophs. In this work we demonstrate for the first time that GH- and secretoneurin (SN) immunoreactivity (the secretogranin II (SgII) fragment) are similarly present in retinal ganglion cells (RGCs), which is an extrapituitary site ...

Molecular mechanism of sphingosine-1-phosphate action in Duchenne muscular dystrophy.
Authors:Nguyen-Tran DH, Hait NC, Sperber H, Qi J, Fischer K, Ieronimakis N, Pantoja M, Hays A, Allegood J, Reyes M, Spiegel S, Ruohola-Baker H,
Journal:
PubMed ID:24077965
'Duchenne muscular dystrophy (DMD) is a lethal muscle-wasting disease. Studies in Drosophila showed that genetic increase of the levels of the bioactive sphingolipid sphingosine-1-phosphate (S1P) or delivery of 2-acetyl-5-tetrahydroxybutyl imidazole (THI), an S1P lyase inhibitor, suppresses dystrophic muscle degeneration. In the dystrophic mouse (mdx), upregulation of S1P by THI increases ... More
