Thermo Scientific Pierce Sulfo-SANPAH es un entrecruzado hetero-bifuncional que contiene un éster N-hidroxisucinimida (NHS) reactivo a aminos y una azida de nitrofenil fotoactivable. Los ésteres NHS reaccionan eficazmente con grupos amino primarios (-NH2) en pH 7–9 en tampones alcalinos para formar enlaces amida estables. La reacción da como resultado la liberación de N-hidroxisuccinimida. Cuando se exponen a la luz UV, las azidas de nitrofenil forman un grupo de nitreno que puede iniciar reacciones de adición con enlaces dobles, inserción en sitios CH y NH o expansión posterior de anillo para reaccionar con un nucleófilo (por ejemplo, aminas primarias). Sulfo-SANPAH, proporcionado como una sal sódica, resulta útil para el entrecruzado de proteínas de la superficie celular y tiene grupos cargados para la solubilidad del agua a una concentración de 10 mM.

Los productos Thermo Scientific No-Weigh son reactivos especiales suministrados en un formato predividido. El envase prepesado evita la pérdida de reactividad del reactivo y la contaminación con el tiempo eliminando la apertura y el cierre repetitivos del vial. El formato permite el uso de un vial de reactivo fresco cada vez, lo que elimina la molestia de pesar pequeñas cantidades de reactivos y reduce las preocupaciones sobre la estabilidad del reactivo.

What are the reactive groups on Sulfo-SANPAH and which groups do they react with?

Sulfo-SANPAH is a heterobifunctional crosslinker that has a sulfo-NHS ester and a photoactivatable nitrophenyl azide group. The sulfo-NHS ester reacts with primary amines in pH 7-9 buffers to form stable amide bonds. When exposed to UV light, nitrophenyl azides form a nitrene group that can initiate addition reactions with double bonds, insertion into C-H and N-H sites, or subsequent ring expansion to react with a nucleophile (e.g., primary amines).

Abstract
Growth cones as soft and weak force generators.
Authors:Betz T, Koch D, Lu YB, Franze K, Käs JA
Journal:Proc Natl Acad Sci U S A
PubMed ID:21813757
'Many biochemical processes in the growth cone finally target its biomechanical properties, such as stiffness and force generation, and thus permit and control growth cone movement. Despite the immense progress in our understanding of biochemical processes regulating neuronal growth, growth cone biomechanics remains poorly understood. Here, we combine different experimental ... More
Tension is required but not sufficient for focal adhesion maturation without a stress fiber template.
Authors:Oakes PW, Beckham Y, Stricker J, Gardel ML
Journal:J Cell Biol
PubMed ID:22291038
Focal adhesion composition and size are modulated in a myosin II-dependent maturation process that controls adhesion, migration, and matrix remodeling. As myosin II activity drives stress fiber assembly and enhanced tension at adhesions simultaneously, the extent to which adhesion maturation is driven by tension or altered actin architecture is unknown. ... More

The matricellular protein periostin is expressed in the skin. Although periostin has been hypothesized to contribute to dermal homeostasis and repair, this has not been directly tested. To assess the contribution of periostin to dermal healing, 6 mm full-thickness excisional wounds were created in the skin of periostin-knockout and wild-type, ... More
Alpha-actinin-4 and CLP36 protein deficiencies contribute to podocyte defects in multiple human glomerulopathies.

PubMed ID:21680739
Genetic alterations of a-actinin-4 can cause podocyte injury through multiple mechanisms. Although a mechanism involving gain-of-a-actinin-4 function was well described and is responsible for a dominantly inherited form of human focal segmental glomerulosclerosis (FSGS), evidence supporting mechanisms involving loss-of-a-actinin-4 function in human glomerular diseases remains elusive. Here we show that ... More

The malignancy of a tumor depends on the capability of cancer cells to metastasize. The process of metastasis involves cell invasion through connective tissue and transmigration through endothelial monolayers. The expression of the glycosylphosphatidylinositol-anchored receptor CD24 is increased in several tumor types and is consistently associated with increased metastasis formation ... More
