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.
Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.

EIF2 is a translation initiation factor that catalyzes the first regulated step of protein synthesis, promoting the binding of the initiator tRNA to 40s ribosomal subunits. eIF2 is composed of 3 non identical subunits, alpha, beta and gamma. Binding occurs as a ternary complex of methionyl-tRNA, eIF2 and GTP. The rate of complex formation is modulated by the phosphorylation state of eIF2alpha. Phosphorylation of eIF2alpha has been shown to occur in response to heat shock and hypoxic stress.
