Abstract Keratin specificity analyses of eight anti-keratin antibodies (34ΒB4 (K1), 35ΒH11 (K8), Ks 13.1 (K13), Ks 19.1 (K19), PKK1, LP34 (CK1), KL1 and AE1) using keratin protein derived from normal thigh epidermis, normal parotid gland and a human squamous cell carcinoma cell line (HSC-5) were performed, and compared with those described in the data sheets. The reactivities of LP34, KL1 and PKK1 were markedly different from those mentioned in the data sheets. The immunostaining pattern of these antibodies in normal skin using formalin-fixed and paraffin-embedded tissue specimens was also examined. The staining patterns of suprabasal keratinocytes (K1, K13, CK1 and KL1 positive), basal cells of the epidermis (PKK1 and AE1 positive), inner cells of the ducts (K8, K13, CK1, KL1 and AE1 positive) and secretory cells of sweat glands (K8, K19, PKK1, KL1 and AE1 positive), mature cells (K8 and KL1 positive) and peripheral cells (CK1, KL1 and AE1 positive) of sebaceous glands and outer root sheaths (PKK1, CK1, KL1 and AE1 positive) were specific. Thus, we conclude that the differentiation of epidermis and skin appendages is possible by immunostaining with these eight anti-keratin antibodies using formalin-fixed and paraffin-embedded tissue specimens with proper protease pretreatment.
