Thermo Scientific Pierce Sulfo-SANPAHは、アミン反応性N-ヒドロキシスクシンイミド(NHS)エステルと光活性可能なニトロフェニルアジドを含有するヘテロ二官能性クロスリンカーです。NHSエステルは、pH 7–9のバッファー中で一級アミノ基(-NH2)と効率的に反応し、安定なアミド結合を形成します。この反応により、スルホ-N-ヒドロキシスクシンイミドが放出されます。ニトロフェニルアジドはUV光にさらされると、ナイトレン基を形成します。ナイトレン基は、二重結合による付加反応、C-HおよびN-H部位への挿入、またはそれに続く環拡大を開始させて、求核試薬(一級アミンなど)と反応できます。ナトリウム塩として供給されるSulfo-SANPAHは細胞表面タンパク質のクロスリンクに有用で、荷電基を有しているため10 mMの濃度まで水に溶解します。

Thermo Scientific No-Weigh製品は、あらかじめ分注された形で提供される特殊試薬です。計量済みのパッケージではバイアルを繰り返し開閉することがないため、経時的な試薬反応性の喪失や汚染を防ぎます。このフォーマットでは、毎回新しい試薬バイアルを使用できるため、少量の試薬を計量する手間がなくなり、試薬の安定性に対する懸念が軽減します。

よくあるご質問(FAQ)

Can you provide the shelf-life for Sulfo-SANPAH?

Sulfo-SANPAH is covered under our general 1-year warranty and is guaranteed to be fully functional for 12 months from the date of shipment, if stored as recommended. Please see section 8.1 of our Terms & Conditions of Sale (https://www.thermofisher.com/content/dam/LifeTech/Documents/PDFs/Terms-and-Conditions-of-Sale.pdf) for more details.

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
Periostin modulates myofibroblast differentiation during full-thickness cutaneous wound repair.

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
Contractile forces contribute to increased glycosylphosphatidylinositol-anchored receptor CD24-facilitated cancer cell invasion.

Journal:J Biol Chem
PubMed ID:21828044
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
