Prinsip ELISA Kit

Prinsip Enzyme-linked Immunosorbent Assay atau ELISA berdasarkan perubahan warna yang terjadi pada substrat pereaksi sesuai dengan label atau imunoprob (immuno probe) konjugat Ab-enzim. Perubahan warna terjadi akibat hidrolisa enzimatik pada reaksi antara konjugat Ab-enzim dengan substratnya, sehingga hasil ELISA lebih sensitive dan dapat dikuantifikasi.

Tahapan umum ELISA biasanya meliputi penempelan (trapping) Ag atau Ab pada media reaksi (solid phase), berupa microwell plate ELISA, diikuti penambahan konjugat Ab-enzim, dan diakhiri dengan penambahan substrat serta buffer penghenti reaksi (blocking buffer).

Salah satu manufacturer ELISA kit adalah Elabscience dari Wuhan China. Umumnya kit ELISA yang diproduksi adalah metode sandwich ELISA, namun ada juga yang metode competitive ELISA. Juga ada kit ELISA quantitative dan qualitative. Tersedia ribuan kit ELISA untuk mendeteksi berbagai macam  marker penyakit. Sudah banyak dijual ELISA kit di Jakarta di Yogyakarta di Bandung di Medan di Padang di Surabaya di Makassar.

Komponen utama perangkat ELISA – misalnya saja kita gunakan sebagai contoh Human TNF-α(Tumor Necrosis Factor Alpha) ELISA Kit cat E-EL-H0109 – yang terdiri atas:

  1. Micro ELISA Plate (Dismountable)
  2. Reference Standard
  3. Concentrated Biotinylated Detection Ab (100×)
  4. Concentrated HRP Conjugate (100×)
  5. Reference Standard & Sample Diluent
  6. Biotinylated Detection Ab Diluent
  7. HRP Conjugate Diluent
  8. Concentrated Wash Buffer (25×)
  9. Substrate Reagent
  10. Stop Solution

Selain Elabscience, Indogen merupakan distributor dari manufacturer CUSABIO, dari Wuhan China juga. Review Cusabio di mata para pelanggan identik dengan kualitas yang cukup baik. Hal ini disebabkan kit ELISA Cusabio melewati quality control yang ketat sebelum digunakan untuk mendeteksi marker yang diteliti. Sehingga harga Cusabio relatif lebih tinggi dibanding Elabscience. Dengan kata lain, Elabscience dari sisi harga lebih kompetitif. Namun, kit ELISA dari Elabscience pun cukup bagus. Hal ini ditunjang dengan protocol atau manual kerja yang jelas dan components kitnya lengkap.

Kedua manufacturer yaitu Elabscience dan Cusabio hanya memproduksi ELISA kit untuk tujuan riset (RUO/Research Use Only), bukan untuk tujuan diagnostic. Tersedia ratusan marker ELISA, yang paling banyak dijual di Jakarta di Yogya di Bandung di Medan di Surabaya (best seller) yaitu marker cytokines, seperti daftar berikut:
