Pantex

What Pantex does

Pantex is a privately held biotechnology company, operating as a division of Bio-Analysis, Inc., that develops and manufactures immunodiagnostic reagents focused on hormone detection. Founded in 1972 and headquartered in Santa Monica, California, the company produces recombinant DNA-derived rabbit monoclonal antibodies, polyclonal antibodies, matching HRP enzyme conjugates, and complete enzyme immunoassay (EIA) kits targeting steroid hormones (testosterone, cortisol, estradiol, progesterone, melatonin, and others), thyroid hormones (T3, T4), and vitamin D. Pantex's underlying technology centers on custom-synthesized steroid haptens conjugated at novel bridge positions to carrier proteins, a homologous assay architecture linking immunogen and enzyme-label conjugates at corresponding steroid positions, and full characterization of antibody specificity against mass spectrometry (LC-MS/MS) before product release. The company holds FDA 510(k) clearances for salivary cortisol and salivary testosterone EIA kits and offers research-use-only assays for melatonin and progesterone.

Pantex monetizes primarily through one-time sales of antibody reagents, HRP conjugates, and EIA kits to clinical laboratories, hospitals, in vitro diagnostic (IVD) manufacturers, distributors, and wholesalers globally. Pricing is quote-based in U.S. dollars with 30-day validity, Net 30 credit terms for established customers, prepay requirements for new customers, and bulk pricing discounts available. The go-to-market is sales-led and direct, with orders processed via email and phone, formal purchase orders required, and an approval workflow for new accounts; international shipments use the purchaser's carrier account and distributor/wholesaler relationships extend indirect reach. The company operates without disclosed external funding, with ownership consolidated under Dr. Romulo Garza since 2003.

Core offering

Pantex develops and manufactures immunodiagnostic reagents focused on hormone detection, including recombinant DNA-produced rabbit monoclonal and polyclonal antibodies against steroid (testosterone, cortisol, progesterone, estradiol, etc.), thyroid (T3, T4), and related hormones. The company also produces matching HRP enzyme conjugates and FDA 510(k)-cleared enzyme immunoassay (EIA) kits, including salivary cortisol and testosterone assays. Products are sold for quantitative measurement in serum, plasma, and saliva to hospitals, clinical laboratories, diagnostic manufacturers, and research institutions worldwide.

Product overview

Pantex is a biotechnology company specializing in antibody development and manufacturing for immunodiagnostics. The company operates as a single unified product portfolio consisting of three core product lines: (1) Steroid Antibodies including both monoclonal and polyclonal rabbit recombinant antibodies targeting hormones such as testosterone, cortisol, progesterone, estradiol, estriol, estrone, DHEA, DHEA-S, androstenedione, aldosterone, corticosterone, melatonin, and 17OH progesterone; (2) HRP Enzyme Conjugates that are in-house developed matching conjugates optimized to work with corresponding antibodies for assay development; and (3) Thyroid Antibodies including ultra-sensitive monoclonal antibodies for T3 and T4 measurements; and (4) Enzyme Immunoassay (EIA) Kits including both FDA 510(k)-cleared diagnostic kits (salivary cortisol and testosterone) and Research Use Only (RUO) melatonin assays. All products are characterized to function in serum, plasma, or salivary immunoassays, with industrial bulk and research quantities available.
