Crosslinkers and Protein Modification Reagents

Biotinylation Reagents

Description

Compared to standard grade equivalents, Premium Grade Reagents provide more clearly defined quality and product support by including each of the following features:

  • increased analytical testing and product characterization
  • greater batch-specific information and quality assurance review
  • more extensive lot sample retention
  • change control notification (CCN)

Highlights:

  • High quality – identity and purity confirmed by several tests, including quantitative NMR
  • Product integrity – enhanced level of testing and characterization compared to standard grade
  • Lot retention – ample supply of past lots retained to ensure future process testing
  • Change management – Change Control Notification (CCN) service
  • Consistent manufacture – batch-specific manufacturing documentation review

Tests and specifications for Premium Grade Reagents compared to standard grade equivalents. We manufacture all reagents to ensure the highest possible overall product integrity, consistency and performance for the intended research applications. The first four tests do not apply to all reagents, but they are used equally for both grades of each to which they are applicable.
