Application

Chromogenic substrate for use with alkaline and acid phosphatase ELISA procedures. Produces a soluble end product that is yellow in color and can be read spectrophotometrically at 405 nm. The pNPP reaction may be stopped with 3 N NaOH and read at 405 nm.

Phosphatase substrate has been used as a substrate in tartrate-resistant acid phosphatase (TRAP) assay and alkaline phosphatase (ALP).

Other Notes

Substrate for the determination of acid and alkaline phosphatases.

Structure (London, England : 1993), 27(10), 1485-1496 (2019-08-14)

ASPP (apoptosis-stimulating proteins of p53) proteins bind PP-1c (protein phosphatase 1) and regulate p53 impacting cancer cell growth and apoptosis. Here we determine the crystal structure of the oncogenic ASPP protein, iASPP, bound to PP-1c. The structure reveals a 1:1

Polyethylenimine600-β-cyclodextrin: a promising nanopolymer for nonviral gene delivery of primary mesenchymal stem cells.

Haijun Tong et al.

International journal of nanomedicine, 8, 1935-1946 (2013-06-06)

Genetically modified mesenchymal stem cells (MSCs) have great potential in the application of regenerative medicine and molecular therapy. In the present manuscript, we introduce a nanopolymer, polyethylenimine600-β-cyclodextrin (PEI600-β-CyD), as an efficient polyplex-forming plasmid delivery agent with low toxicity and ideal

Gluten exacerbates IgA nephropathy in humanized mice through gliadin-CD89 interaction.

Christina Papista et al.

Kidney international, 88(2), 276-285 (2015-03-26)

IgA1 complexes containing deglycosylated IgA1, IgG autoantibodies, and a soluble form of the IgA receptor (sCD89), are hallmarks of IgA nephropathy (IgAN). Food antigens, notably gluten, are associated with increased mucosal response and IgAN onset, but their implication in the
