  In this paper we construct a multivariable link invariant arising from the
quantum group associated to the special linear Lie superalgebra sl(2|1). The
usual quantum group invariant of links associated to (generic) representations
of sl(2|1) is trivial. However, we modify this construction and define a
nontrivial link invariant. This new invariant can be thought of as a
multivariable version of the Links-Gould invariant. We also show that after a
variable reduction our invariant specializes to the Conway potential function,
which is a version of the multivariable Alexander polynomial.
