Either aptamers or these proteins are the heat-sensitive components of hot-start PCR (20[1])mastermix. These proteins are conjugated to nanoparticles and are dried onto the test line in most lateral flow assays. To indicate where they were raised, these proteins’ names may (20[1])start “alpha-goat” or “alpha-sheep.” (20[1])A primary one of these proteins, (20[1])used for capture, (20[1])is sandwiched (20[1])with a secondary one, used for detection, (20[1]0[1])in an (20[2])(*) ELISA (“eliza”) or a Western (10[3])blot. (10[3])Serology testing (10[1])detects these (10[1])proteins. Clonal variants of these proteins (10[1])are synthesized (10[2])by (10[1])hybridoma cultures of B cells. Cocktails (10[1])of (0[1])these proteins (10[1])are used therapeutically (10[1])to harness adaptive immunity to neutralize pathogens. (10[1])For 10 points, name (10[1])these proteins (10[2])that tightly bind to (10[1])antigens. (10[1]0[1])■END■ (10[3]0[1])
