IMMUNOHISTOCHEMISTRY PROCEDURE (PAP TECHNIQUE) FOR MAB305, MONOCLONAL ANTIBODY TO CHOLINE ACETYLTRANSFERASE
I) Perfusion & Sectioning Procedure
1. Perfuse through the heart with a fixative solution containing 4% paraformaldehyde in 0.12 M phosphate buffer (pH 7.3) for light microscopy (LM), and additionally, 0.1% gluteraldehyde and .002% CaCl2 for electron microscopy (EM).
2. Remove brain and postfix 2-18 hours at 4°C in 4% paraformaldehyde in 0.12 M phosphate buffer.
3. After brain is blocked for sectioning, wash in several changes of buffer for 2-3 hours.
4. Specimens for EM are sectioned on a Vibratome (50 μm) and rinsed in buffer, those for LM should be cryoprotected in 30% sucrose in buffer.
5. After freezing with dry ice, 30-40 μm thick sections of LM specimens are cut on a cryostat.
6. Sections are rinsed, and then stored in phosphate buffer containing 0.1% sodium azide.
II) Staining Procedure
Tissue is processed as freely-floating sections in continuously agitated solutions. All incubations are performed at room temperature unless otherwise stated.
1.a. For localizing ChAT-positive somata and dendrites:
Sections are washed in 0.1 M Tris-buffered saline (TBS; containing 1.4% NaCl, pH 7.3) only. No detergent or enzyme pretreatment is used.
b. For localizing ChAT-positive terminal-like structures:
Incubate sections in TBS (pH 8.1) for 5 minutes at 37°C. Transfer sections to TBS (pH 8.1) containing pronase (1.2 μg/mL) for 1 1/2-2 minutes at 37°C, followed by several ice cold buffer washes for a total of 5 minutes. The concentration of pronase and incubation time of the digestion should be evaluated for each region examined.
c. For localizing ChAT immunoreactivity and subsequently counterstaining the sections:
Incubation in TBS containing 0.1%-0.8% Triton X-100 for 15 minutes may increase the tissue penetration of the immunoreagents, but it also raises the background staining.
2. Incubate sections in normal goat serum (3-5%) for one hour. The working solutions of all antisera should also contain similarly diluted normal goat serum.
3. Incubate in anti-ChAT monoclonal antibody solution (Suggested working dilution 1:250, final working dilution must be determined by end user) for 2 hours at room temperature and then for an additional 6-18 hours at 4°C.
4. Incubate with second antibody (i.e. Goat anti-Mouse IgG, Cat. No.: AP124, dilution 1:50-100) for 1-2 hours.
5. Incubate with diluted PAP complex (i.e. Mouse PAP, Cat No.: PAP14, conc. 25-50 μg/mL) for one hour.
6. After rinsing in buffer, the second antibody and PAP steps are repeated for 40 minutes to 1 hour each in order to amplify staining intensity, particularly of small ChAT-containing structures.
7. React for 15 minutes with 0.06% 3,3'-diaminobenzidine×4 HCl (DAB; diluted in phosphate buffered saline, pH 7.3) and 0.006% H2O2.
8. Specimens for routine LM are postfixed for 1 minutes in 0.005% OsO4 (osmium tetraoxide), and then mounted, dehydrated and coverslipped. Selected regions blocked for EM are postfixed in 2% OsO4 for 1 hour, en bloc stained with uranyl acetate, and flat-embedded in Epon-Araldite resin.生物信息 免疫原品种 Choline acetyltransferase purified from rat brain. 克隆 1E6 浓缩 Please refer to the Certificate of Analysis for the lot-specific concentration. 宿主 Mouse 特异性 Recognizes cholinergic neurons in the brain and spinal cord (CNS). 同种型 IgG1 品种反应性 RatHumanMonkey 抗体类型 Monoclonal Antibody Entrez基因编号 - NM_020986.2

Entrez基因汇总 Cholinergic systems are implicated in numerous neurologic functions. Alteration in some cholinergic neurons may account for the disturbances of Alzheimer disease. The protein encoded by this gene synthesizes the neurotransmitter acetylcholine. Alternative splice variants have been found that contain alternative 5' untranslated exons. Three of the four described splice variants encode identical 69 kDa proteins while one variant encodes both the 69 kDa and a larger 82 kDa protein. 基因符号 - EC 2.3.1.6

纯化方法 Unpurified UniProt编号 - P28329
UniProt汇总 FUNCTION: SwissProt: P28329 # Catalyzes the reversible synthesis of acetylcholine (ACh) from acetyl CoA and choline at cholinergic synapses.
SIZE: 748 amino acids; 82568 Da
DISEASE: SwissProt: P28329 # Defects in CHAT are the cause of familial infantile myasthenia gravis 2 (FIMG2) [MIM:254210, 254200]; also known as CMS-EA. FIMG2 patients have myasthenic symptoms since birth or early infancy, negative tests for anti-AChR antibodies, and abrupt episodic crises with increased weakness, bulbar paralysis, and apnea precipitated by undue exertion, fever, or excitement. Inheritance is autosomal recessive.
SIMILARITY: SwissProt: P28329 ## Belongs to the carnitine/choline acetyltransferase family.产品使用声明 使用声明 - Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.
