  • 一次抗体 備考

    Voltage-sensitive calcium channels mediate the entry of calcium into many types of excitable cells and thus play a key role in neurotransmitter release and excitation-contraction (E-C) coupling. The 1,4-dihydropyridines (DHPs) are synthetic organic compounds which can be used to identify the L-type calcium channels that are found in all types of vertebrate muscle, neuronal and neuroendocrine cells. The DHP receptor is part of the L-type calcium channel complex and is thought to be the voltage sensor in E-C coupling. The purified DHP receptor isolated from triads is composed of at least four subunits. The alpha-1 subunit contains the binding site for the DHPs and shows high sequence homology to the voltage gated sodium channel. The alpha-2 subunit is a large glycoprotein associated with the DHP receptor which was first described in skeletal muscle and is also found in high concentrations in other excitable tissues such as cardiac muscle and brain and in low concentrations in most other tissues studied. The other two subunits that co-purify with the DHP receptor are termed beta and gamma.

  • 機能

    Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death. The isoform alpha-1S gives rise to L-type calcium currents. Long-lasting (L-type) calcium channels belong to the 'high-voltage activated' (HVA) group. They are blocked by dihydropyridines (DHP), phenylalkylamines, benzothiazepines, and by omega-agatoxin-IIIA (omega-Aga-IIIA). They are however insensitive to omega-conotoxin-GVIA (omega-CTx-GVIA) and omega-agatoxin-IVA (omega-Aga-IVA). Calcium channels containing the alpha-1S subunit play an important role in excitation-contraction coupling in skeletal muscle.

    Defects in CACNA1S are the cause of periodic paralysis hypokalemic type 1 (HOKPP1) [MIM:170400]; also designated HYPOPP. HOKPP1 is an autosomal dominant disorder manifested by episodic flaccid generalized muscle weakness associated with falls of serum potassium levels.
    Defects in CACNA1S are the cause of malignant hyperthermia susceptibility type 5 (MHS5) [MIM:601887]; an autosomal dominant disorder that is potentially lethal in susceptible individuals on exposure to commonly used inhalational anesthetics and depolarizing muscle relaxants.
    Defects in CACNA1S are the cause of susceptibility to thyrotoxic periodic paralysis type 1 (TTPP1) [MIM:188580]. A sporadic muscular disorder characterized by episodic weakness and hypokalemia during a thyrotoxic state. It is clinically similar to hereditary hypokalemic periodic paralysis, except for the fact that hyperthyroidism is an absolute requirement for disease manifestation. The disease presents with recurrent episodes of acute muscular weakness of the four extremities that vary in severity from paresis to complete paralysis. Attacks are triggered by ingestion of a high carbohydrate load or strenuous physical activity followed by a period of rest. Thyrotoxic periodic paralysis can occur in association with any cause of hyperthyroidism, but is most commonly associated with Graves disease.

  • 配列類似性

    Belongs to the calcium channel alpha-1 subunit (TC 1.A.1.11) family. CACNA1S subfamily.

  • ドメイン

    Each of the four internal repeats contains five hydrophobic transmembrane segments (S1, S2, S3, S5, S6) and one positively charged transmembrane segment (S4). S4 segments probably represent the voltage-sensor and are characterized by a series of positively charged amino acids at every third position.
    The loop between repeats II and III interacts with the ryanodine receptor, and is therefore important for calcium release from the endoplasmic reticulum necessary for muscle contraction.

    Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CACNA1S antibody [1A] (ab2862)

    Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) was performed on normal biopsies of deparaffinized human skeletal muscle tissue. Heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer, microwaved for 8-15 minutes. Tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then incubated with ab2862 (1:20) or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP, followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

Cells were blocked with a 2% solution of BSA-PBS for 30 min at room temperature and incubated with a Dihydropyridine Receptor alpha-1 monoclonal antibody at 1 µg/test for 40 min at room temperature. Cells were then incubated for 40 min at room temperature in the dark using a Dylight 488-conjugated secondary antibody and re-suspended in PBS for FACS analysis.

Question

What dilution was tested in IP with these antibodies?

Read More
Answer

Thank you for your enquiry. Regarding the two antibodies, ab2862 and ab2825, I was able to find the specific antibody concentrations for you. The concentration of ab2825 (PMCA ATPase) is 7.7 mg/ml and the concentration of ab2862 (Dihydropyridine Receptor Alpha-1) is 3.8 mg/ml. I would recommend a range for immunoprecipitation assays, 10-500 ug of sample to 0.5-5 ug of antibody. Based on resources I have available, I would recommend starting in the mid-range. I hope this information helps. Please let me know if I can be of further assistance.

Question

I wonder if I can use this antibody for a Western Blot with mouse skeletal muscle TT membranes. Will I have problems because of the anti mouse secondary antibody? What protocol do you recomend me for Western and IP?

Read More
Answer

Thank you for your enquiry. This antibody has been shown to work by Western blot; detecting a ~200 kDa protein corresponding to the DHP receptor in rat skeletal muscle extracts. You shouldn't have too much of a problem with your IP and western experiments given that IgG migrates at ~50KDa and therefore wont interfere with your targeting of DHPR alpha 1. I would recommend the use of low leaching protein A agarose and localising your blot for all products >100KDa by cutting your membrane with a scalpel. I thought that I would mention that DHPR alpha 1 was detected in skeletal muscle in the following publication. http://www.jbc.org/cgi/reprint/277/52/50535 Zheng Z, Wang ZM, Delbono O. Insulin-like growth factor-1 increases skeletal muscle dihydropyridine receptor alpha 1S transcriptional activity by acting on the cAMP-response element-binding protein element of the promoter region. J Biol Chem. 2002 Dec 27;277(52):50535-42. Epub 2002 Oct 28. Erratum in: J Biol Chem. 2003 May 2;278(18):16453. PMID: 12407098 I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Answer

Thank you for your enquiry. I am sorry that ab2862 is not working for you. Since you are using the antibody in a tested application for a species that the antibody has been shown to cross-react with, this should work. Without knowing the exact problem you are having, I can only make general suggestions assuming you are seeing no staining. Have you tried blocking with 10% goat serum in place of BSA? You may wish to try this for 30 minutes at room temperature. In addition, you may wish to try incubating with the primary antibody overnight at 4 degrees. If you could give me further details of the protocol you are using by submitting the form below, I would be happy to look into this further and try to help you to get this antibody to work. https://www.abcam.com/index.html?section=ihc&pageconfig=technical&intAbID=2862&mode=questionaire I hope this information helps, please do not hesitate to contact us if you need any more advice or information.
