Catalog Number: (103523-926)
Supplier: Invitrogen
Description: Thermo Scientific Pierce SMCC is a hetero-bifunctional crosslinker that contain N-hydroxysuccinimide (NHS) ester and maleimide groups that allow covalent conjugation of amine- and sulfhydryl-containing molecules. NHS esters react with primary amines at pH 7–9 to form amide bonds, while maleimides react with sulfhydryl groups at pH 6.5–7.5 to form stable thioether bonds. In aqueous solutions, NHS ester hydrolytic degradation is a competing reaction whose rate increases with pH. The maleimide group is more stable than the NHS-ester group, but will slowly hydrolyze and lose its reaction specificity for sulfhydryls at pH values > 7.5. For these reasons, conjugations with these crosslinkers are usually performed at pH 7.2–7.5, with the NHS ester (amine-targeted) reacted before or simultaneous with the maleimide (sulfhydryl-targeted) reaction.

Catalog Number: (PI23295)
Supplier: Invitrogen
Description: Thermo Scientific™ Peptide Digest Assay Standard is a validated protein digest reference sample optimized for use in quantitative peptide assays to improve reproducibility and accuracy.Robust peptide assay standard—the only commercially available peptide digest standard that has been developed for use in a quantitative peptide assayValidated—validated for both the Pierce Quantitative Fluorometric Peptide Assay and the Pierce Quantitative Colorimetric Peptide Assay with comparable standard curves using both assaysStable—liquid formulation is stored at 4⁰C, eliminating variability due to freeze-thawsEasy-to-use—provided in a liquid format with a known peptide concentrationThe Peptide Digest Assay Standard was designed as reference standard for use with the Pierce Quantitative Fluorometric and Colorimetric Peptide Assays to augment the reproducibility and accuracy of peptide quantitation in a microplate-based assay.The reference protein has been digested with MS-grade trypsin to minimize missed cleavages

Catalog Number: (PI88341)
Supplier: Invitrogen
Description: The Thermo Scientific™ Pierce™ BSA Protein Digest Standard, LC-MS Grade, is a validated protein digest optimized for use as a quality control sample for liquid chromatography (LC) and mass spectrometry (MS) analysis of proteomic samples.Positive control sample—BSA digest optimized and validated as a quality control standard for mass spectrometry applicationsExcellent sequence coverage—greater than 85% sequence coverageValidated peptide quality—digestion procedure optimized for minimal missed cleavages and over-alkylationRigorously tested—high-quality, consistent BSA protein digest documented via lot-specific certificates of analysisStable—provided in a stable lyophilized formatThe Pierce BSA Protein Digest Standard is produced using high quality bovine serum albumin (BSA) and mass spectrometry-grade trypsin. The BSA is fully reduced, alkylated (iodoacetamide), and desalted (C18) after trypsin digestion to provide a quality LC/MS-grade standard that is free of intact protein. The peptide digest standard provides excellent sequence coverage with minimal over-alkylation and missed cleavages. This digest standard has been robustly tested for peptide quality, digestion efficiency, and lot-to-lot uniformity and is suitable for LC and LC-MS applications.
