Abstract: A modified igNAR peptide sequence derived from a wild-type igNAR peptide sequence is diversified by mutating the amino acid sequence at 50% or more of the amino acids in the CDR3 loop region and optionally at 50% or more of the amino acids in the CDR3 loop region. The modified igNAR peptide may have the sequence of SEQ ID NO: 8, 10 or 50 to 85. The modified igNAR peptides have binding activity against albumin protein sequences, such as human serum albumin. These modified igNAR peptides may have utility in extending the in vivo half-life of biological molecules e.g. therapeutic agents, and so may be used in medicine.

Abstract: A disposable car seat, vehicle seat or other seat liner that may include: Version A, being sheet material having a top surface of an absorbent material and a bottom surface of non-permeable material; having several line points at the upper middle, lower middle, left and right sides of middle, and left and right sides of upper, outer edges to accept car seat belt hook-ups; an elasticized outer edge; a backing of light adhesive. Version B of invention includes: sheet material of the same qualities as version A; light adhesive backing; line point to accommodate hook-up belt of a protective arm; closure tabs on upper and lower edges. Version C designed for a booster seat, vehicle seat or other seat includes same material, line points and adhesive backing as version A; elasticized edge on central left and right sides that stand up forming a well or barrier.
