SQOPT is a software package for solving large-scale linear and quadratic programs. The quadratic objective function may be positive definite or semidefinite (convex). Efficiency is best if many constraints are active at a solution.
SNOPT is a software package for solving large-scale optimization problems (linear and nonlinear programs). It employs a sparse SQP algorithm with limited-memory quasi-Newton approximations to the Hessian of Lagrangian.
NPSOL is a software package for solving constrained optimization problems (nonlinear programs). It employs a dense SQP algorithm and is especially effective for nonlinear problems whose functions and gradients are expensive to evaluate.
LSSOL is a software package for solving constrained linear least-squares problems and convex quadratic programs (definite or semidefinite), including linear programs. Dense matrices are assumed throughout.
Eat1 and Eat2 are monoclonal antibodies (mAbs) which specifically recognize mouse CD81. It is shown that Eat1 binds to the large extracellular loop (EC2), while Eat2 requires the presence of both extracellular loops for binding.
