General description
Serum albumin is the most extensive plasma protein in the circulatory system. It is produced within the liver and exported as a non-glycosylated protein to the blood plasma. The molecular weight of native serum albumin is around 66 kDa. Native serum albumin is a negatively charged protein.
Acetylation of bovine serum albumin particularly modifies lysine (Lys) residues with elevated frequency, with lesser degrees of modification of serine (Ser) and threonine (Thr) residues. MALDI-TOF mass spectrometry analysis of acetylated BSA has indicated an increased MW of about 3000, compared to native BSA (Ostatná, V. et al., J. Electroanalytical Chem., 821, 97-103 (2018)).. This acetylation process also derivatizes similar amino acid residues in any trace contaminating nucleases in the BSA, to inactivate that nuclease activity. This makes acetylated BSA useful in molecular biology applications where trace nuclease activity must be minimized.

Application
Acetylated BSA has been used as a component of the reaction mixture for adapter ligation. In addition, this B8894 acetylated BSA product has been used in other applications, such as:
- In cDNA library preparation (Hafner, M. et al., RNA, 17(9), 1697-1712 (2011))
- As a blocking agent with streptavidin beads used for capture of biotinylated RNA (Winz, M.-L. et al., Nat. Protocol., 12(1), 122-149 (2017))
Acetylated to inactivate nucleases commonly found in BSA. Acetylated BSA should not be used as a protein standard since acetylation of tyrosine residues prevents color development in the Lowry assay and other similar protein determinations.
Biochem/physiol Actions
Native serum albumin plays a major role in maintaining the pH and osmotic pressure of the blood. It is also involved in transporting a diverse range of endogenous and exogenous metabolites, such as amino acids, fatty acids, drugs, steroids and metal ions. Native serum albumin can have a role in modulating the levels of Ca2+ and Mg2+ metals in blood.
Features and Benefits
This acetylated BSA product has been tested for the following properties:
- DNase-free / Exonuclease-free
- Nickase-free / Endonuclease-free
- Protease-free
- RNase-free

Eukaryotic RNAs can be modified with a non-canonical 5' nicotinamide adenine dinucleotide (NAD+) cap. NAD-seq identifies transcriptome-wide NAD+ capped RNAs. NAD-seq takes advantage of click chemistry to allow the capture of NAD+ capped RNAs. Unlike other approaches, NAD-seq does not

The heterogeneity of DNA methylation within a population of cells necessitates DNA methylome profiling at single-cell resolution. Recently, we developed a single-cell reduced-representation bisulfite sequencing (scRRBS) technique in which we modified the original RRBS method by integrating all the experimental

Distinct classes of small RNAs, 20-32 nucleotides long, play important regulatory roles for diverse cellular processes. It is therefore important to identify and quantify small RNAs as a function of development, tissue and cell type, in normal and disease states.
