Example Embodiment

[0044] Embodiment 1: The composition of special hemolysin for flow cytometry is as follows:

[0045] NaCl 8g

[0046] Na 2 HPO 4 .12H 2 O 2.89g

[0047] K H 2 PO 4 0.2g

[0048] KCl0.2g

[0049] Paraformaldehyde 30g

[0050] Add double distilled water to 1L

[0051] Preparation:

[0052] 1. Weighing of raw materials: Weigh all the required raw materials according to the above formula proportions.

[0053] 2. Preparation: Mix various weighed raw materials, put them in a 50°C water bath for 4 hours, and stir and mix them every 30 minutes.

[0054] 3. Filtration: filter with double-layer filter paper to remove the precipitate.

[0055]Then carry out product sub-packaging: the filtered product is sub-packaged, 50ml / bottle. Label the packaged products, and mark the instructions for use and precautions. The finished product is accepted and put into storage.

Abstract

It is a process method of hemolysin in special cell device and its application, which belongs to medical test agent technique field. The hemolysin is composed of NaCI, Na#-[2] HPO#-[4]íñ12H#-[2] O, KH#-[2] PO#-[4], cavaform and double stilled water. Each component is mixed and is put in the water for four to five hours and is shaken every thirty to forty minutes and to be filtered to get the agent. The hemolysin in this invention is used as surface marks of leucocyte in blood tested by the flow cell device.

Description

(1) Technical field [0001] The invention relates to a hemolysin used in detecting the surface markers of various groups of blood leukocytes (lymphocytes, monocytes and granulocytes) by a flow cytometer, a preparation method and an application thereof. (2) Background technology [0002] Flow cytometry has been used in various fields of scientific research and medical clinical testing, such as the examination of immune function, detection of tumor antigens, transfer genes, tumor suppressor genes and other disease-related genes, apoptosis, diagnosis and prognosis of AIDS, etc. With the popularization and application of flow cytometer, the development and manufacture of its supporting reagents are becoming more and more important. At present, the hemolysin used in flow cytometry basically depends on imports, mainly products from Becton Dickinson (BD) and Beckman Coulter in the United States, which are expensive and cannot be supplied in time, causing great inconvenience and wast...
