Toxin公司于1984年成立，目的是向工業界和科學界提供的葡萄球菌毒素和抗毒素。此外，服務組件 公司成立是為了檢測食品和培養上清液中是否存在葡萄球菌毒素。該公司的創始人R.F.Reiser醫生和R.H.Deibel醫生是外派人員。 TS在各自領域的葡萄球菌研究公司成立時。Reiser博士在葡萄球菌腸桿菌的純化和鑒定方面有豐富的經驗。 是毒素休克綜合征毒素的。Deibel博士是威斯康星大學麥迪遜分校細菌系的主席，他也曾在那里做過。 食品中葡萄球菌和沙門氏菌生長及其毒素在動物模型中作用的研究。副總裁兼實驗室PaulBina于19歲加入Tox技術公司。 工作人員已增加到8名雇員，其中包括4名板凳科學家。目標是是為科學界提供盡可能高質量的毒素和相關產品。在服務方面，我們的政策是提供 對細菌毒素和霉菌毒素進行快速、靈敏和有效的檢測。

該公司的生產線已擴大到包括由鏈球菌和大腸桿菌生產的毒素。兔和羊制備的多克隆抗體可用于大多數 e毒素和小鼠單克隆抗體正在加入，因為他們可以使用。該公司的服務部門現在包括檢測額外的細菌毒素和霉菌毒素以及Perfor。 明血清中存在抗葡萄球菌和鏈球菌毒素的抗體。合同研究服務可用于毒素生產和毒素產品挑戰研究領域。這些研究 ES可以根據良好的實驗室實踐標準(GLPS)進行。

Listeria Monocytogenes typing antibodies

General technical information

These antibody reagents have been developed in rabbits and are specific for

the somatic and flagellar antigens of Listeria monocytogenes.  They may be 

used to identify and characterize different serotypes of L. monocytogenes.  

The reagents are sold in a lyophilized form and are under vacuum.  In this

            evacuated, freeze-dried form, the antibodies are stable for several years when

            stored at - 20 ⁰C or lower.

To rehydrate the antibody reagents, it is recommended to add an equivalent 

volume of deionized water (usually l ml) to the vial, then aliquot the content to

convenient working volumes and freeze any of the aliquots which will not be

used within several days.  The shelf life of the rehydrated reagent is

            approximay one week at 4 ⁰C and one year at - 20  ⁰C.

To prepare an aliquot of rehydrated reagent for use in the FDA-BAM serological

            typing procedure, dilute the reagent to the recommended dilution with PBS-

           Tween (0.01 M phosphate, 0.9 % NaCl, 0.05 % Tween-20, pH to 7.4) The diluted

working reagent should be used within 8 hours.
