일반 설명
Bovine serum albumin (BSA) that belongs to the serum albumin family, is an α-helical, globular and non-glycosylated protein. It comprises three domains with two subdomains under each domain.
애플리케이션
Bovine Serum Albumin has been used:
- as a component of cryomedia for freezing testicular tissue
- to resuspend myometrial cells in flow cytometric analysis for cell viability quantification
- to block cardiac fibroblasts (CFs) for immunofluorescence staining
생화학적/생리학적 작용
Bovine Serum Albumin (BSA) is a transporter for drugs, hormones, and fatty acids. It displays high solubility and is exploited in the cosmetic and pharmaceutical industries. BSA is useful as a cell media component and favors embryonic stem cells (hESC)differentiation.
Certain conformational and primary-sequence epitopes of BSA are suspected allergens in human beef and milk allergies.
제조 메모
Derived from New Zealand source serum
Prepared using heat shock fractionation
Serum albumin may be referred to as Fraction V. This naming convention is taken from the original Cohn method of fractionating serum proteins using cold ethanol precipitation. Serum albumin was found in the fifth ethanol fraction using Cohn′s method. Since then, the term "Fraction V" has been used by some to describe serum albumin regardless of the method of preparation. Others have used this term to describe serum albumin purified by ethanol fractionation methods that have been highly modified since the original Cohn method was described. Sigma-Aldrich manufactures and distributes serum albumins purified from a variety of primary methods including the true Cohn fractionation method, modified ethanol fractionation methods, heat shock and chromatography. Additional purification steps may include crystallization or charcoal filtration.

The dual oxidase-thiocyanate-lactoperoxidase (Duox/SCN(-)/LPO) system generates the microbicidal oxidant hypothiocyanite in the airway surface liquid by using LPO, thiocyanate, and Duox-derived hydrogen peroxide released from the apical surface of the airway epithelium. This system is effective against several microorganisms that

The actin cytoskeleton of dendritic spines plays a key role in morphological aspects of synaptic plasticity. The detailed analysis of the spine structure and dynamics in live neurons, however, has been hampered by the diffraction-limited resolution of conventional fluorescence microscopy.

The aim of the current study is to determine whether butein (3,4,2',4'-tetrahydroxychalcone) exhibits antiproliferative effects against tumor cells through suppression of the signal transducer and activator of transcription 3 (STAT3) activation pathway. We investigated the effects of butein on constitutive
