CAS No.: 16354-58-8
Purity:  ≥98.0%
Synonyms: N-Acetyl-L-serine
N-Acetylserine (N-Acetyl-L-serine) is a complement pathway modulator targeting activated third complement protein (C3b) and an amino-terminal residue (an N-terminal acetylation modification group). N-Acetylserine reacts with the exposed thioester group of C3b via its hydroxyl group, thereby blocking the covalent binding of glycerol to this thioester group. N-Acetylserine widely exists in soluble proteins of mammalian cells (accounting for approximately 80% of such proteins). N-Acetylserine has a blocking property that prevents direct Edman sequencing of proteins; deblocking is achievable through trifluoroacetic acid-catalyzed N→O acetyl migration followed by β-elimination. N-Acetylserine is suitable for sequencing of proteins with N-terminal acetylserine modification .

CAS No.: 616-02-4
Synonyms: Methylmaleic anhydride
Citraconic anhydride (Methylmaleic anhydride) is a derivative of maleic anhydride (HY-Z0060) and novel antigen retrieval solution. Citraconic anhydride reversibly blocks protein amino groups, stabilizing specific enzymes and improving their catalytic performance. Citraconic anhydride reacts with free amino groups on proteins (especially lysine residues), converting positively charged NH3 + into carboxyl groups, thereby disrupting methylene bridge crosslinks caused by Formaldehyde during antigen retrieval. Citraconic anhydride functionalizes Isotactic polypropylene. Citraconic anhydride precisely responds to pH changes to achieve reversible modification. Citraconic anhydride is irritating to skin and eyes .

Infection

N-Succinimidyl bromoacetate (NHS-Bromoacetate) is a heterobifunctional crosslinking reagent, mainly used to modify the ɛ-amino group of lysine side chains. By covalently linking its bromoacetyl moiety to the ɛ-amino group of lysine in peptidomimetics, N-Succinimidyl bromoacetate enables their conjugation with thiol-modified nanoparticles via thioether bonds. N-Succinimidyl bromoacetate also performs bromoacetylation modification on carrier proteins, which then forms stable thioether bonds with the thiol groups of cysteine in peptides, thus efficiently preparing soluble peptide-protein conjugates with high substitution ratios. N-Succinimidyl bromoacetate can be used to prepare activated Sepharose derivatives for affinity chromatography, protein affinity labeling reagents, and peptide-protein immunogen conjugates with non-immunogenic linkages. N-Succinimidyl bromoacetate is applicable to studies related to HIV-1 infection and glioblastoma multiforme .
