Featured products

Selected from our partners’ ranges for this category.

Cat. no. BP-20609

Mal-PEG4-acid

  • Maleimide + acid
  • PEG4 spacer
  • Purity 98%

PEG linker with a thiol-reactive maleimide and a terminal carboxylic acid that forms an amide bond with amines (EDC or HATU); the PEG spacer increases aqueous solubility.

Cat. no. BP-24290

DBCO-PEG2-acid

  • DBCO
  • PEG2 spacer
  • Purity 97%

DBCO group for copper-free click chemistry plus a terminal carboxylic acid that couples to primary amines; the PEG chain adds water solubility.

Cat. no. BP-24335

Val-Cit

  • Cleavable ADC linker
  • Cathepsin B
  • Purity 98%

Cleavable ADC linker designed to be cut by cathepsin B, an enzyme found in the lysosome, so the payload is released only inside the cell.

What to expect

Shipping & storage

Linkers ship at ambient temperature or on ice packs; storage (often –20 °C, dry) is on each datasheet.

Delivery

Lead time depends on supplier stock and is confirmed with your quote.

On arrival

Store as per the datasheet straight away. Let vials reach room temperature before opening — reactive groups such as NHS esters are moisture-sensitive.

Commercial

INR pricing available. GST invoice provided with every order.

Quality and applications

Why linker choice matters

the linker decides when and where the payload is released, so it drives an ADC’s efficacy and safety.

Typical applications

antibody-drug conjugates, protein PEGylation to improve stability and solubility, and reducing the immunogenicity of biologics.
