  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

KSR1 antibody was raised against recombinant human KSR protein.
Recognizes the kinase suppressor of Ras (KSR). KSR was initially considered to be a protein kinase acting in the Ras pathway, but has more recently been demonstrated to act as a scaffold protein, facilitating complex formation between RAF and MEK and ERK.
Immunohistology: Methacarn fixation recommended for paraffin embedded tissues.


PBS, 0.09% sodium azide.
For research use only.

About KSR1

Q8IVT5 U43586 AAC50354.1

KSR1 Antibody, B-KSR1 Antibody, KSR Antibody, RSU2 Antibody, Kinase suppressor of ras Antibody, Kinase suppressor of ras 1 Antibody

Kinase suppressor of Ras (KSR) is involved in the regulation of the Ras activated MAPK pathway. KSR contains some kinase activity, phosphorylating Raf-1 at Thr269 in response to Ras stimulation. One study found this was necessary for the optimal activation of Raf-1 in response to EGF. Further studies popularly supported the idea that KSR acts as a scaffolding protein for the Ras stimulated MAPK pathway by supporting the formation of a large complex.

Western blot

Western blot
Western blot of myc-tagged murine KSR expressed in COS cells using Rat anti-Human KSR (LS-C44281) and visualized using ECL (note detection of myc tag as control using anti-c-myc clone 9E10).
