Protein Function and Analysis

Life Sciences

From the fastest, most efficient site-directed mutagenesis kits to their tandem affinity purification kit for the discovery of new protein interactions, Stratagene offers innovative research tools to analyze your protein's function.

Next Generation Performance

Stratagene's new QuikChange® Lightning Site-Directed Mutagenesis Kit delivers faster, ultra-high fidelity results with their exclusive QuikChange® Lightning DNA polymerase fusion and optimized Dpn I enzyme. Engineered for speed and accuracy, their QuikChange® Lightning enzymes provide significantly shorter thermal cycling and digestion times with the same ultra-high fidelity as their QuikChange® II kits.

Isolate Key Interacting Partners from Mammalian Cells

Stratagene's InterPlay™ Mammalian Tandem Affinity Purification (TAP) System helps you identify protein-protein interactions with their gentle, two-step purification protocol. Interacting proteins remain bound after washing while background protein levels are reduced. The InterPlay Mammalian TAP systems consist of all of the vectors, resins and buffers required to conduct a TAP experiment. The two systems offer either N- or C-terminal fusion of your protein of interest to the CBP and SBP tags, and each vector is supplied in all three reading frames.

Create Multiple Mutant Clones Together

Introduce multiple point mutations simultaneously with Stratagene's QuikChange® Multi Site-Directed Mutagenesis Kits. Stratagene's easy three-step non-PCR procedure can be completed in just one day so you can get your mutant clone faster.
